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.
