Polyurethane Chemical Additive and PU Raw Material Manufacturer

Who We Are

Pioneers in Sustainable Polyurethane Innovation

Polyurethane Catalyst Experts

Guangzhou Yourun Synthetic Material Co., Ltd. is a high-tech enterprise integrating R&D, production, and sales of polyurethane chemical components. We focus on eco-friendly alternatives to toxic catalysts such as mercury, lead, and dibutyltin dilaurate (DBTDL).

Our mission is to provide safer, more sustainable solutions for the polyurethane industry, especially in the CASE (Coatings, Adhesives, Sealants, Elastomers) sector. Our catalysts are engineered for high performance without compromising environmental responsibility.

With years of technical expertise and a commitment to innovation, Yourun has become a trusted partner for manufacturers seeking reliable, green polyurethane formulations.

• Low VOC formulations possible

PU Foam Catalyst

Optimized for flexible and rigid foam production, ensuring uniform cell structure and dimensional stability.

• Controls foam rise and set time
• Reduces shrinkage
• Works with polyether and polyester polyols

Polyurethane Chain Extender

Diamines and diols used to enhance mechanical properties in cast elastomers (CPU), thermoplastic polyurethanes (TPU), and RIM systems.

• Increases tensile strength
• Improves abrasion resistance
• Customizable reactivity profiles

Polyurethane Anticatalyst

Delays premature curing in two-component systems, extending pot life without sacrificing final properties.

• Controls reaction onset
• Ideal for large castings
• Compatible with aromatic and aliphatic isocyanates
