A-223-40-50MIL-P: Pigmented LSR Cartridge 50ml (40 Shore A)

A-223-40-50MIL-P (LSR 4340) Pigmented Cartridge – Shore A 40

A-223-40-50MIL-P is part of the Elkem LSR 4300 Series, a platinum-cure liquid silicone rubber supplied in a convenient 50 mL pre-pigmented cartridge system. With a Shore A 40 durometer, this material offers enhanced strength, durability, and structural integrity while maintaining good flexibility.

Each cartridge is pre-pigmented at 2%, providing consistent, uniform color throughout. Custom pigment loadings are available upon request for more translucent or more opaque finishes.

This two-part, 100% solids system mixes in a 1:1 ratio and cures via addition-cure (platinum) chemistry to form a tough, resilient elastomer with excellent mechanical performance.
