Message

It is a soft, colorable, special non-hygroscopic thermoplastic vulcanized elastomer (TPV) in the thermoplastic elastomer (TPE) series. It is suitable for non-fat food contact materials. This brand of Shanduping TPV is a shear rate dependent product that can be processed on conventional thermoplastic injection molding or blow molding equipment. This is a polyolefin-based material that can be recycled in the production process.
