Polyurethane and Polymer Additive Optimize Your Polymers

Bio-SAH™ 362 Powder – Anti-Hydrolysis Agent

Bio-SAH™ 362 Powder is a monomeric carbodiimide compound that effectively prevents hydrolytic degradation in PU and engineering polymers. By reacting with carboxylic acids and water, it forms stable urea linkages, halting autocatalytic hydrolysis and extending the material's service life.

Applications:

-Thermoplastic Polyurethane (TPU): Enhances hydrolysis resistance, improving tensile strength and elongation under humid and high-temperature conditions.

-Polyester Polyurethane Adhesives: Prevents degradation, maintaining bond strength and durability in challenging environments.

-Polyurethane Shoe Soles: Increases lifespan by mitigating hydrolytic breakdown, ensuring long-lasting wear.

Diol-HCA™ HQEE / HER – Chain Extenders

Diol-HCA™ HQEE and HER are advanced chain extenders that enhance the molecular weight and mechanical properties of PU systems. These additives facilitate the formation of high-performance elastomers with improved strength and elasticity.

Applications:

-Polyurethane Elastomers: Improves tear strength and abrasion resistance, making them suitable for demanding applications.

-Automotive Components: Enhances durability and performance of parts such as bumpers and seals.

-Industrial Applications: Provides robust materials for conveyor belts and other heavy-duty uses.

Amine-HCA™ C3-LF – Delayed/Amine-Based Chain Extenders

Amine-HCA™ C3-LF is widely used as a delayed-action curing agent in single-component polyurethane systems, offering both processing flexibility and storage stability.

Applications:

-Single Component Sealant Systems: Ideal for moisture-curing polyurethane sealants used in construction and industrial assembly. The delayed reactivity allows easy mixing at room temperature and long pot life before application.

-Single Component Synthetic Leather Slurry: Used in the production of artificial leather, C3-LF ensures uniform polymer chain extension without premature crosslinking. This enables better surface finish and mechanical properties.

-Tires for Large Mining Machinery: In heavy-duty polyurethane tire casting, especially in mining and industrial applications, C3-LF provides a stable processing window, excellent flow during mold filling, and reliable post-curing mechanical strength under pressure or rotary casting conditions.
