UV Cure

Industries & Applications

UV-cure silicone rubber belongs to a new class of rubber that offers high cure speed at low temperatures. UV light initiates crosslinking through a photochemical reaction, not heat. The rubber can be processed via injection molding with special molds or via extrusion without additional heat cure. Momentive UV-cure technology offers the possibility to produce parts and combinations that were previously difficult to manufacture, since heat curing processes limit the use of temperature sensitive ingredients. And, this new technology can help save energy.

Silopren UV LSRs are two-component liquid silicone rubbers with a mixing ratio of 100:2.  Silopren UV LSRs can be molded quickly at low temperatures by using a typical injection molding process with UV light. Scorch performance can be controlled due to the low temperature with less shrinkage and air entrapment. Due to low cavity pressure, the clamping forces are also minimized. Our Application Development Center experts can help you design the material and the mold.
