High-Stiffness PP Homopolymer for Injection Molding – FDA Compliant, Ideal for Medical, Household & Packaging Applications
Lotte Chemical Titanpro® 6331 is a high-quality polypropylene homopolymer engineered for general-purpose injection molding. Known for its excellent stiffness, dimensional stability, and ease of processing, this resin delivers consistent performance across a wide range of industrial applications. With a high heat deflection temperature (99°C at 4.6 kg/cm²), low water absorption (0.02% after 24 hours), and FDA compliance for food contact, Titanpro® 6331 is ideal for manufacturing durable closures, medical devices, household goods, toys, containers, and writing instruments. Its balanced mechanical properties, including good impact strength and Rockwell hardness of 97 R, ensure reliability in both lightweight and demanding applications.
