A-225-70-50MIL: LSR Cartridge 50ml (70 Shore A)

A-225-70-50MIL (LSR 4370) Cartridge – Shore A 70

A-225-70-50MIL is part of the Elkem LSR 4300 Series, a platinum-cure liquid silicone rubber supplied in a convenient 50 mL cartridge system. With a Shore A 70 durometer, this material provides maximum strength, rigidity, and durability, making it ideal for the most demanding structural applications.

This two-part, 100% solids system is supplied as a pumpable, translucent paste. When Parts A and B are mixed in a 1:1 ratio, the material cures via addition-cure (platinum) chemistry to form a tough, optically clear elastomer with excellent mechanical performance.
