LSR Seal, known as LSR Silicone Seal & LSR Sealing Gasket or LSR Gasket, which is made from platinum cured liquid silicone rubber (LSR) materials by liquid silicone rubber injection molding, and is widely used in electronic, automotive, sanitary and medical areas etc.
Why choose LSR (liquid silicone rubber) as elastomeric seal & sealing gasket?
LSR Seal (injection molded) vs Silicone Seal (compression molded)
LSR Seal 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 Seal 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 Seal & Gasket can meet all food grade and medical requirements or certifications. Good food, water and medical contact, safe applications. 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. LSR seals 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 Seal can meet all required approvals like UPS Class VI, BfR XV, FDA 21 CFR 177.2600 etc. More and more food, water and medical contact products or device will choose LSR & liquid silicone rubber as sealing gasket materials in future.
LSR Seal have higher tear resistance and tensile strength. more information, please surf: LSR & Liquid silicone rubber properties:
LSR Seal different applications:
LSR Bottle Seal, use liquid silicone rubber as material is mainly because it's high security property and is water proof, can resist oxidation and some chemical materials.
Medical LSR Gasket, LSR Seal & Gasket is popular in medical area becuase it is a two-part platinum-cured, high-purity and non-toxic, and can also resists to bacteria growth.
Automatic LSR Seal, which not only have good sealing performance, but also not stain or corrode other materials and also burns to form water vapor and carbon dioxide, not halogens.
