Why choose to use liquid silicone rubber?

The performance characteristics and fast curing cycle of molded and manufactured silicone rubber make liquid silicone rubber an ideal choice for small molded parts. Unlike most thermoplastic elastomers (TPR and TPE), LSR remains flexible and elastic at temperatures as low as -58°F and retains its properties at temperatures as high as 392°F. Liquid silicone rubber is very suitable for gaskets, seals and cushions in portable communications, data acquisition instruments and rugged electronic equipment under harsh outdoor conditions. The curing cycle in liquid injection molding allows a 1- or 2-cavity mold to produce a compression mold with a higher number of cavities.liquid silicone products


In addition to the mechanical, chemical, and thermal properties of LSR, there are many other reasons to specify this type of material. From a manufacturability perspective, several key factors stand out. One of the biggest reasons customers might end up using LSR materials is geometry. Any 3D shape that cannot be manufactured in a flat configuration requires a molding process—usually for such parts, high production levels justify the increased cost of tools associated with LSR molding.


In addition, some customers may have flat gaskets, but the thickness tolerance requirements are very strict. In these cases, its sheet forming capabilities can be used to maintain tighter tolerances in small sheets, which can then be used for die cutting or waterjet cutting of flat washers and gaskets.
