A-221-05-400MIL-P: Pigmented LSR Cartridge 400ml (05 Shore A)

A-221-05-400MIL-P (LSR 4305) Pigmented Cartridge – Shore A 05

A-221-05-400MIL-P is part of the Elkem LSR 4300 Series, a platinum-cure liquid silicone rubber supplied in a 400 mL pre-pigmented cartridge system for higher volume dispensing applications. With a Shore A 05 durometer, this material offers very soft flexibility with improved strength, making it ideal for applications requiring softness with added durability.

Each cartridge is available in 38 pigment options, pre-mixed for consistent, uniform color throughout. Standard pigment loading is 2%, with custom pigment levels available upon request for more translucent or more opaque finishes.

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, flexible elastomer with excellent clarity and performance.
