Description

Grade 370 rubber is a high tear strength rubber for the casting of polyurethane resins.
Its high tear strength permits castings to be made with larger than normal under cuts. Due to its softness and flexibility, 370 rubber is particularly good for when there are deep undercuts.
For casting in Clear PU plesae use Grade 400.

Pale blue (when mixed) Comes complete with hardener – mix-ratio is 5 parts of hardener to 100 parts of rubber.
