Elkem LSR-4360 Silicone Elastomer (A-225-60)

A-225-60 (LSR 4360) Liquid Silicone Rubber – Shore A 60

A-225-60 is part of the Elkem LSR 4300 Series, a platinum-cure liquid silicone rubber designed for liquid injection molding (LIM) and applications requiring high strength, rigidity, and durability. With a Shore A 60 durometer, it provides a firm, resilient elastomer suited for more demanding structural applications.

This two-part, 100% solids system is supplied as a pumpable, colorless, 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.
