Product Application
Our polyester polyols can be applied in the following fields:
PU Spandex (Elastane)
Low-molecular-weight aliphatic polyester polyols are selected. The produced spandex boasts high tenacity, grease resistance and anti-aging properties, suitable for sport fabrics and elastic fibers for undergarments.
PU Flooring & Polyurethane Waterproof Membrane
Aliphatic polyester polyols can be used for high-performance PU flooring and roof waterproof coatings. Featuring high mechanical strength, chemical resistance and abrasion resistance, they are ideal for factory workshops and parking lot floors.

Product Properties
PU Spandex (Elastane)
Low-molecular-weight aliphatic polyester polyols are selected. They have regular molecular chains and stable terminal hydroxyl activity. The produced spandex features high tenacity, excellent resilience, grease resistance and anti-aging performance, and the fiber is not easy to break. The strong polarity brought by ester bonds forms soft segment structures when reacted with isocyanates, which endow the fibers with long-lasting elasticity. It is suitable for sport fabrics and elastic filaments for undergarments.
PU Flooring & Polyurethane Waterproof Membrane
Aliphatic polyester polyols are adopted. They offer high mechanical strength, good abrasion resistance and chemical resistance. The cured coating film has strong adhesion to substrates and excellent tensile and tear properties. With anti-aging and non-yellowing characteristics (aliphatic system), the coating resists cracking and can withstand vehicle rolling and chemical splashes. It is suitable for factory workshops and parking lot roof waterproof flooring.
