SANTOPRENE® BALLS

Vulcanized thermoplastic elastomer polyolefinic  material balls, they combine the quality of rubbers (flexibility and durability) with easiness on workability of thermoplastic materials.
Applications
Check valves, diaphragm pumps, automotive field, they are used even as floating elements.
