Product description
LSR-5140 is two components additional curing type liquid silicone rubber. It is cured with Platinum type catalyst & mix rate is 1:1. It is non-poisonous & no smell. It must be cured at heating temperature. It has extraordinary properties, as low linear shrinkage, high transparency, high tear resistance, high tensile resistance, high temperature resistance (limit 300℃) & long lifetime etc. It is a new & popular technology product applied widely in all trades & industries.
Application:
LSR-5140 is applied in making high transparent, high tear resistance & high tensile resistance products, as food grade O-rings, sealing rings, gasket, food contact fittings & nipple, etc.
