Product Description
FLEXATHENE TP 4308-HR is a Thermoplastic Polyolefin (TPO) formulated for compounding and injection molding applications that require medium stiffness and excellent cold temperature impact resistance. TP 4308-HR is specially formulated for paintable applications and meets the GMP.E/P.023 specification. TP 4308-HR is produced in a proprietary gas-phase process, which yields a product with greater resistance to mechanical and thermal degradation and more uniform dispersion than melt-blended rubber compounds. This product is readily reprocessible with minimal changes to processing characteristics or physical properties. This product is also available in UV stable grades.
