Have you ever wondered why some materials last longer in wet conditions? The secret lies in anti-hydrolysis agents. These agents protect polymers from water-induced breakdown, extending their lifespan. In this post, you'll learn what anti-hydrolysis agents are, why preventing hydrolysis is crucial, and get an overview of the market for these essential additives.
Anti-hydrolysis agents protect polymers from breaking down when exposed to water or moisture. Hydrolysis causes chemical bonds, especially ester bonds in polymers like PET or PU, to split apart. This leads to weaker materials and shorter product lifespans.
These agents work by reacting with the harmful by-products of hydrolysis. When water breaks the polymer chains, carboxylic acid groups form. These acids can speed up further breakdown in a process called autocatalytic hydrolysis. Anti-hydrolysis agents neutralize these acids, stopping the chain reaction.
For example, carbodiimide-containing agents react quickly with carboxyl groups, forming stable urea linkages. This reaction removes the acid groups, preventing further damage and preserving the polymer’s structure. This process can also help "repair" broken chains by grafting fragments back together, restoring some material strength.
Carbodiimide is a key functional group in many anti-hydrolysis agents. It’s highly reactive specifically toward carboxyl groups produced during hydrolysis. When carbodiimide meets a carboxyl group, it forms a stable urea compound. This reaction effectively "locks" the acid group, stopping it from catalyzing more hydrolysis.
Polycarbodiimide, a polymerized form, offers even better performance due to its multiple reactive sites and enhanced stability. This makes it ideal for long-lasting protection in harsh environments like high humidity and temperature.
Carbodiimide-based agents do not easily react with other chemicals like peroxides or sulfuric acid at room temperature, which adds to their reliability during processing and use.
Anti-hydrolysis agents, especially those based on carbodiimide, are chemically stable under normal conditions. They resist oxidation and do not degrade easily, ensuring they remain active throughout the material’s lifetime.
Their stability allows them to be incorporated during polymer processing without losing effectiveness. They improve melt viscosity and mechanical strength by increasing molecular weight through chain extension or crosslinking.
Moreover, these agents enhance processing stability for recycled or remanufactured materials. They also improve compatibility between different polymers, which is useful in blends or composites.
| Property | Description |
|---|---|
| Reactivity | Targets carboxyl groups to form stable urea |
| Stability | Resistant to oxidation and chemical degradation |
| Processing Benefits | Increases melt strength and viscosity |
| Long-term Protection | Prevents autocatalytic hydrolysis |
| Compatibility | Enhances polymer blend stability |
In summary, anti-hydrolysis agents, particularly carbodiimide-based ones, act by chemically neutralizing acids formed during hydrolysis, repairing broken polymer chains, and stabilizing the material’s structure. This mechanism preserves polymer properties and extends product life under challenging conditions.
Anti-hydrolysis agents play a vital role in extending the life of polymer materials. When polymers like PET, PU, or PLA encounter moisture, their molecular chains can break down through hydrolysis. This breakdown weakens the material, causing it to lose strength and durability over time. By incorporating anti-hydrolysis agents, the harmful effects of water are minimized. These agents react with the acids formed during hydrolysis, neutralizing them and stopping further chain scission. As a result, the polymer’s structure remains intact longer, significantly increasing the product’s service life. For example, in high-humidity environments, polyester fibers treated with these agents maintain their strength far better than untreated ones.
Hydrolysis not only shortens material lifespan but also changes physical properties such as flexibility, tensile strength, and appearance. Over time, untreated polymers may become brittle, discolored, or lose elasticity. Anti-hydrolysis agents help preserve these key properties by stabilizing the molecular structure. They prevent the formation of carboxylic acid groups that catalyze further degradation, maintaining the polymer’s original characteristics. This is especially important in applications like films, coatings, and textiles, where consistent performance and appearance are critical. For instance, TPU materials treated with carbodiimide-based anti-hydrolysis agents retain their elasticity and toughness even after prolonged exposure to moisture.
In addition to protecting finished products, anti-hydrolysis agents improve the stability of polymers during processing. Hydrolysis can occur during melt processing, extrusion, or molding when moisture is present. This leads to lower molecular weight and poorer mechanical properties in the final product. Anti-hydrolysis agents reduce chain scission during these steps by reacting with moisture-related degradation products. This results in higher melt viscosity and better mechanical strength, making the polymer easier to process and shape. Moreover, these agents enhance the stability of recycled or remanufactured materials, which often contain moisture or degradation by-products. They also improve compatibility between different polymers in blends or composites, ensuring uniformity and performance.
| Benefit | Description | Example Application |
|---|---|---|
| Material Longevity | Prevents chain breakdown, extends product lifespan | Polyester fibers, automotive parts |
| Physical Property Retention | Maintains flexibility, strength, and appearance | TPU films, coatings |
| Processing Stability | Enhances melt strength and viscosity, stabilizes recycled materials | Injection molding, extrusion |
Together, these benefits make anti-hydrolysis agents indispensable in industries relying on ester-based polymers or moisture-sensitive materials. They help manufacturers deliver durable, high-quality products capable of withstanding harsh environmental conditions.
In the automotive world, parts often face harsh conditions — heat, moisture, chemicals. Rubber seals, hoses, gaskets, and plastic components are especially vulnerable to hydrolysis. When these materials degrade, it can cause leaks, failures, or reduced safety. Anti-hydrolysis agents step in here. They protect polymers by neutralizing acids formed during hydrolysis, preventing chain breakdown. This keeps parts flexible, strong, and reliable over time.
For example, polyurethane (PU) and thermoplastic polyurethane (TPU) used in automotive parts benefit greatly. Adding carbodiimide-based anti-hydrolysis agents extends their service life, even under high humidity or temperature. These agents also improve processing stability during manufacturing, ensuring consistent quality. As a result, vehicles stay safer and last longer, reducing maintenance costs.
Textiles face constant exposure to moisture — rain, sweat, washing. Natural and synthetic fibers can weaken or lose color due to hydrolysis. Anti-hydrolysis agents help fabrics resist these effects. They protect fibers by blocking water’s damaging action and neutralizing acidic by-products.
Polyester fabrics, widely used in clothing and upholstery, are common candidates for these agents. Treatment with anti-hydrolysis additives maintains strength, elasticity, and appearance even after repeated washing or exposure to humid environments. This means clothes keep their fit and color longer, enhancing customer satisfaction.
Additionally, these agents help maintain fabric softness and prevent brittleness. This is crucial for sportswear, outdoor gear, and technical textiles that demand durability and comfort. Anti-hydrolysis agents also improve dye retention, reducing fading over time.
In construction, materials like sealants, coatings, adhesives, and polymer-based composites often face moisture and weathering. Hydrolysis can cause cracking, loss of adhesion, or reduced mechanical strength, threatening structural integrity.
Anti-hydrolysis agents are incorporated into these materials to enhance their resistance. For instance, sealants used around windows or doors maintain flexibility and adhesion longer when treated. Coatings on concrete or metal surfaces resist moisture penetration, preventing degradation.
Moreover, these agents improve the durability of polymer-modified concretes and waterproof membranes. This leads to longer-lasting buildings and infrastructure, reducing repair needs and costs.
| Industry Sector | Typical Materials Protected | Benefits of Anti-Hydrolysis Agents |
|---|---|---|
| Automotive | PU, TPU, rubber seals, hoses | Extended part life, improved processing stability |
| Textile & Apparel | Polyester, nylon, blended fabrics | Maintained strength, color retention, flexibility |

Anti-hydrolysis agents have proven their worth in many polymer industries by significantly improving product durability. For example, in the production of polyurethane (PU) foams used in footwear soles, carbodiimide-based anti-hydrolysis agents have extended the lifespan of these products. The agents react with carboxyl groups formed during hydrolysis, preventing chain scission and maintaining mechanical strength. This results in shoes that resist moisture damage and retain flexibility longer, reducing product returns and boosting customer satisfaction.
Another success story comes from the polyethylene terephthalate (PET) film industry. PET films are widely used in packaging and electrical insulation but are prone to hydrolytic degradation under high humidity. Incorporating polycarbodiimide anti-hydrolysis additives into PET formulations has helped manufacturers enhance hydrolysis resistance. This leads to films with improved tensile strength and clarity even after prolonged exposure to moisture, making them ideal for demanding applications like solar panel back sheets and food packaging.
Polyester-based products, such as fibers, films, and molded parts, often face hydrolysis challenges. Hydrolysis breaks ester bonds, weakening the material and causing loss of tensile strength and flexibility. Anti-hydrolysis agents, especially those containing carbodiimide groups, neutralize the acids formed by hydrolysis. This slows down the degradation process and preserves polymer integrity.
In textile manufacturing, polyester fibers treated with anti-hydrolysis agents maintain their strength and elasticity after repeated washing cycles. This treatment reduces fabric brittleness and color fading, enhancing garment lifespan. In automotive applications, polyester-based components like fuel lines and radiator hoses benefit from these agents by resisting moisture-induced cracking, thus improving vehicle safety and reliability.
When compared to other stabilizers, carbodiimide-based anti-hydrolysis agents offer unique advantages. Unlike general antioxidants or UV stabilizers, which protect primarily against oxidation or ultraviolet light, anti-hydrolysis agents specifically target the hydrolytic degradation pathway. Their ability to chemically react with carboxyl groups sets them apart, providing a direct mechanism to stop chain scission.
Other stabilizers, such as phosphites or hindered amine light stabilizers (HALS), may offer some indirect protection against hydrolysis but lack the targeted reactivity of carbodiimide compounds. Additionally, carbodiimide agents do not interfere with processing additives or catalysts, maintaining product quality during melt processing.
In terms of processing, anti-hydrolysis agents improve melt viscosity and mechanical properties by promoting chain extension or mild crosslinking. This contrasts with some stabilizers that solely act as passive protectants. The active chemical role of carbodiimide agents often translates to superior long-term performance in moisture-rich environments.
| Stabilizer Type | Primary Function | Hydrolysis Protection | Processing Impact | Typical Applications |
|---|---|---|---|---|
| Carbodiimide Anti-Hydrolysis | Neutralizes acids, repairs chains | High | Improves melt strength | Polyester fibers, PU parts |
| Antioxidants | Prevent oxidation | Low | Minimal | General polymers |
| UV Stabilizers (HALS) | Protects against UV light | Low | Minimal | Outdoor plastics, coatings |
| Phosphites | Scavenges radicals | Moderate | Some improvement | Polyolefins, packaging films |
