Polypropylene Resin - Durable Resin for Industrial and Coating Applications

‌Product Overview‌

Polypropylene Resin (PP) is a ‌versatile, semi-crystalline thermoplastic‌ engineered to deliver exceptional durability, lightweight performance, and corrosion resistance across industrial and coating applications. With a melt flow index (MFI) range of 2–45 g/10min (230°C/2.16kg) and customizable copolymer/homopolymer grades, this resin combines ‌>95% chemical inertness‌ (pH 1–14), ‌thermal stability up to 160°C‌, and ‌low moisture absorption (<0.01%)‌ for use in aggressive environments. Ideal for automotive under-the-hood components, corrosion-resistant tank linings, and powder coating additives, it offers ‌100% recyclability‌, ‌FDA/EU food contact compliance‌, and ‌halogen-free flame retardancy‌ (UL94 V-0 achievable) to meet modern industrial sustainability goals.
