Liquid silicone rubber (LSR) is a two-part silicone-based polymer joined together by a chemical bond. It’s most commonly used to create injection molded parts for products used in industries such as automotive, food, appliances, textiles, and consumer goods.
Liquid Silicone Rubber (LSR) is a two-component system, where long polysiloxane chains are reinforced with specially treated silica. Component A contains a platinum catalyst and Component B contains methylhydrogensiloxane as a cross-linker and an alcohol inhibitor.
LEDs used for illumination and TV backlights in particular must provide long-lasting reliability, which makes silicone a vital material for the manufacture of such LEDs. Silicone is used as an encapsulant and die-bonding adhesive, and manufacturers are working toward using it as a reflector material.
Global LED lens liquid silicone rubber market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Momentive Launches Next-Generation Ultra Clear Liquid Silicone Rubber.Momentive Performance Materials Inc. (Momentive) will showcase Silopren* LSR 7180 liquid silicone rubber, a new addition to the Ultra Clear Silopren LSR 7000 series, at LIGHTFAIR International (LFI) in San Diego.
By providing improved flame resistance while maintaining good optical clarity and long-term color stability in harsh conditions, this grade offers new benefits to applications that require high flame retardant properties such as outdoor and specialty lighting.
“Momentive is a pioneer in LSR technology and 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. “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.
” In addition, it offers UL 94 V1 and 5VA flame class ratings and is f1(1) rated for outdoor use in accordance with UL 746C. This additional feature can offer significant performance enhancement for LED lighting and optical applications.
Silopren LSR 7180 liquid silicone rubber will be featured in a live-demonstration in collaboration with industry partner Sur-Seal in their booth (#523) at LFI 2016. This demonstration will showcase the processing qualities and benefits of Silopren LSR 7180 liquid silicone rubber for injection moulding to make precise optic parts for a variety of LED lighting and optical related applications
