WATERFORD, N.Y. — Momentive Performance Materials Inc. released a new silicone product, SiloprenTM LSR 7180 liquid silicone rubber, an addition to the Ultra Clear Silopren LSR 7000 series. By providing improved flame resistance while maintaining good optical clarity and long-term color stability in harsh conditions, the new grade is said to offer new benefits to applications that require high flame retardant properties, such as outdoor and specialty lightings.

“This new offering further strengthens our robust product portfolio of liquid silicone rubbers for the LED lighting and optic industries,” said Hee-Seok Hwang, senior global project manager, in a press release. “For LED lighting applications such as optics, lenses, and light guides that require high lumen efficiency, excellent light transmission, and stability to heat, Silopren LSR 7180 liquid silicone rubber is an excellent material to consider.”

The use of Silopren LSR 7180 liquid silicone rubber is said to be beneficial when using injection molding to make precise optic parts for a variety of LED lighting and optical related applications.

Momentive Performance Materials Inc. (momentive.com), a prominent developer of silicones and advanced materials, exhibited Silopren LSR 7180 liquid silicone rubber at Lightfair International (LFI) in San Diego in April.
