Code: SYL-1434


- +


Grade 400 rubber is a high tear strength rubber for the casting of clear polyurethane resins.
Its high tear strength permits castings to be made with larger than normal under cuts. Grade 400 is the only Silicone Rubber which should be used with Clear PU Resins. Using other grades will result in imperfect hardening.
