We are offering the PPDI-based prepolymers and thermoplastic elastomer chips. PPDI (p-polyphenylene diisocyanate) is a structurally symmetric aromatic diisocyanate and is mainly used to produce polyurethane elastomeric products with a tighter hard segment and high-performance properties that conventional polyurethane products could not match. Besides the standard products listed below, we also provide the polyurethane products with specific properties requested by the customers.  

PPDI-terminated Prepolymers (with low free PPDI)

PPDI-based Thermoplastic Polyurethane

PPDI-based thermoplastic polyurethanes are offered as pellets, are readily injection moldable and can

l     Perform well where other polyurethane materials fail at the elevated temperatures

l     Have high wear-resistance for extended seal life and excellent resistance to compression set

Drying and Injection Molding Conditions：

1.      Drying conditions: 80-95 °C in a forced air oven for 4-6 hours

2.      Setting for Injection Molding
