SINPOLENE REINFORCED PP COMPOUND
SINPOLENE GPP is a series of glass fiber reinforced polypropylene designed for injection molding. The difference in content and characteristics between the individual grades allows GPP series to meet stringent requirements such as high heat distortion temperature, enhanced rigidity/impact strength and dimensional stability.
