Liquid Silicone Rubber
Liquid Silicone Rubber also called as Liquid Silicone, LSR, Clear Silicone Rubber Liquid, LSR Silicone, which can be divided into Food Grade Liquid Silicone and Medical Grade Liquid Silicone. For common Liquid Silicone Rubber, that can achieve Food Grade, and if need to achieve complete 100% Medical Grade, will need second vulcanization.
Liquid Silicone Rubber is safe can resistant bacteria growth and will not stain or corrode other materials. LSR offers low water absorption and excellent resistance to common chemicals even when exposed to extreme temperatures. Liquid Silicone is widely used in Medical areas for many medical assessories. Such as Silicone Nasal Mask, Full Face Mask, Silicone Nasal Plug, Silicone Connector, Silicone Menstrual Cups, Silicone Valve and Gasket for Resuscitator, LSR Seals.
Liquid Silicone is a self bonding material, which offers primerless adhesion to various substrates. LSR's self-bonding propertity make it works well on glass filled nylons, stainless steel, aluminum and polysulfones. It not only offers a perfect solution for composite seals to reduce assembly components, but also provide a better sealing performance between two mating components.
Liquid silicone rubber has very good compatibility with human tissue and body fluids, which is solid silicone can not achieve. So for many medical device related to human body, Liquid Silicone Rubber is the first/best choice.
Liquid Silicone Rubber parts have large temperature range ( –60°C to +180°C.), can withstand extreme high and low temperatures, so liquid silicone not only an ideal choice for medical device because of high safefy, but also a good choice for cars components that close to engines and need high temperature resistance.
Liquid silicone rubber injection molded parts are fire retardant and will not melt, which is a superior advantage compared to plastic injection molded parts. Cured LSR materials provide excellent resistance to UV rays, weathering, and aging. They are ideal for use in applications where long-term exposure to the elements is a concern.
Liquid Silicone Rubber can achieve the lowest hardness 5 ShoreA, for solid silicone can only be 20A, for many babycare products will LSR is a good option because it low hardness and softness. Liquid Silicone Rubber also has good elongation, high tear and tensile strength, and excellent flexibility.
