LSR Silicone Gasket

Liquid Silicone Rubber Gasket, knowns as LSR silicone seal & LSR Sealing Gasket or LSR Gasket, which made from platinum cured liquid silicone rubber (LSR) materials by liquid silicone rubber injection molding, and widely used in electronic, automotive, sanitary and medical areas etc.

LSR Silicone Gasket

Silicone Gasket also known as Silicone Seal, LSR Seal, LSR Gasket, Liquid Silicone Rubber Seal, Liquid Silicone Sealing, Liquid Silicone Rubber Seal, which is made of Liquid Silicone Rubber (LSR) by Liquid Silicone Rubber Injection Molding (LIM), and is widely used in electronic and medical areas  for the high material safety requirement (FDA medical grade and food grade) and strict tolerance.

Why Liquid Silicone is a better choice for sealing gaskets?

Liquid silicone rubber is a versatile material and is preferred over other polymers especially in medical applications due to its biocompatibility, heat resistance, flexibility, self-lubrication, oil resistance and part quality.

LSR also used widely in automotive, electrical, and consumer products.  Injection molding of LSR products is gaining in popularity as it enables high-volume production, fast cycle times, automated processing and manufacturing of intricate shapes.

LSR Silicone Seal

LSR Silicone Gasket's advantages:

LSR Silicone Gasket is safer, like FDA medical grade & food grade seal & gasket for medical device, medical products or baby care products. as liquid silicone rubber is a  two-part platinum-cured silicone, which is a high-purity and non-toxic materials. LSR can meet all required approvals, such as UPS Class VI, BFR XV, FDA 21 CFR 177.2600 etc. More and more food, water, and medical contact products or devices will choose LSR& liquid silicone rubber as material.

LSR is an inorganic nature, which is clean, plasticizer-free, tasteless, and is water proof, can resist oxidation and some chemical materials like acids and alkali. Liquid silicone rubber also resists to bacteria growth, which will not stain or corrode other materials and also burns to form water vapor and carbon dioxide, not halogens, not toxins etc.

Umbrella Valve

Silicone Seals and Gasket made of liquid silicone rubber is more precision: mini parting line, less silicone rubber flashing, stable seal's designs and sizes tolerance. Especially for lsr overmolded (2-Shot overmolding) with plastic or metal parts etc.

LSR Silicone gasket also can be sterilized by steam antoclaving, ethylene oxid, gamma, e-beam etc. Liquid silicone rubber has demonstrated superior compability with human tissue and body fluids. LSR is an inorganic nature, which is clean, plasticizer-free, tasteless, and is water proof, can resist oxidation and some chemical materials like acids and alkali.
