The Hidden Crisis of Polyurethane Hydrolysis: KSTO’s additive Breaks the Performance Bottleneck

SUZHOU, China, 2026 – With the rapid development of the polyurethane industry towards high-end and multi-scenario applications, hydrolysis has become a key bottleneck affecting the service life and performance of polyurethane products, making high-efficiency hydrolysis resistance agents an indispensable core auxiliary for global manufacturers. For polyurethane materials, especially polyester-based polyurethane systems widely used in industrial and high-end scenarios, hydrolysis is not a superficial damage, but an irreversible internal chain reaction that directly leads to product failure, performance degradation and huge economic losses.

Polyurethane hydrolysis is mainly triggered by moisture, high temperature and humid working environments. The ester bonds inside the polymer molecular chain are easily broken under water and heat erosion, producing carboxyl groups that further catalyze the continuous spread of hydrolysis, forming a vicious cycle. This process causes polyurethane products to lose mechanical strength rapidly, showing brittleness, cracking, deformation and bonding failure, which greatly shortens the service life and limits their application in harsh environments.

Currently, polymeric carbodiimide-based hydrolysis resistance agents are widely recognized as the most effective solution in the industry due to their excellent hydrolysis inhibition performance. As a core supplier in the polyurethane additive industry, Suzhou KSTO New Materials Technology Co., Ltd. independently researches and produces the carbodiimide hydrolysis resistance agent Series. Relying on ten years of R&D experience and patented technologies, this product is specially developed to solve the hydrolysis problem of polyurethane materials at the root.

In terms of operation, liquid than powder features easy dispersion, good compatibility with various polyurethane substrates, and can be added directly during the material mixing process with a recommended addition amount of 0.5%-2.0%. It effectively blocks the autocatalytic hydrolysis chain reaction of polyurethane, stabilizes the molecular structure, significantly improving the product’s water resistance, thermal stability and service life. It is widely applicable to polyurethane elastomers, coatings, adhesives, sealants and other high-value fields.

With strict full-process quality control, batch-to-batch stable performance and customizable technical support, KSTO’s polymeric carbodiimide provides reliable technical support for the high-quality development of the global polyurethane industry, helping downstream manufacturers break through product performance bottlenecks, reduce after-sales risks, and expand application boundaries in the global high-end market.
