Liquid Silicone Rubber "expands" product line. (Materials).
Offered in a hardness range of 5 to 80 Shore A and a viscosity range of 1000 to 7 million cps, the LSR and RTV compounds are available in small-batch and large-batch custom formulations; the cure rate is varied to optimize cure efficiencies and extend shelf life, and batches can be custom colored. CR1-SIL says its low-volatile, ultra-clear,, LSR compounds are compliant with U.S. Food & Drug Administration (FDA) Article 21, and are suited for applications in which purity, aesthetics, soft touch, and anti-shock properties are desired.
The company reports that its line of LSR products offers benefits to manufacturers because of reduced cycle times, flash-free parts, no post cure, and no mold fouling. In some cases, LSRs are said to have reduced cure times, with a CRI-SIL cure package, from as much as 10 minutes to less than 30 seconds. Benefits of the RTV products are reported to be higher tear strengths in a wide durometer range.
