Liquid Silicone Rubber (LSR). It is a kind of non-toxic, heat-resistant and highly resilient flexible hot solid material. It is liquid, good fluidity, fast vulcanization, low viscosity, fast curing. Large quantities of fast and repeatable machinery can be produced by injection molding. Compared with traditional materials, liquid injection molding silica gel has the advantages of short molding cycle, high automatic molding degree, low vulcanization temperature, no by-products in the vulcanization process, high product accuracy and long service life.
The properties of liquid silica gel are cured only by crosslinking. LSR has been used where conventional and thermoplastic elastomers (Tpes) reach their limits. LSR also has very good resilience, high heat resistance, low temperature flexibility, high electrical insulation properties, tensile and re-failure strength, and it is physiologically harmless. Having these material properties, single dyeing and the ability to combine with various metals and plastics makes liquid silicone widely used. In addition to a growing number of material types, for example: in addition to the standard types of various Shore hardness, there are medical technology, petroleum, oil thermal dialysis, electrical conductivity, flame retardant, fast crosslinking or additional focus modification and types made with silicon fluoride.
Liquid silicone (LSR) features:
Non-toxic and tasteless, excellent transparency, waterproof, breathable, resistance to high and low temperature without loss of elasticity, high tear strength, compression permanent deformation rate is small, copy product size precision, in line with FDA biocompatibility, excellent electrical insulation, combustion will not produce harmful substances. Of course, this is also the characteristics of silicone materials.
Liquid silicone is suitable for the process: liquid injection molding (LIM), impregnation, perfusion, molding.
The range of liquid silicone should be:
Daily necessities: such as trademarks, pacifiers, mobile phone protective cases.
Electronic appliances: such as waterproof and moisture-proof electronic components, shipping, insulation coating and potting materials.
Medical equipment: medical larynx, medical silicone cup, implant material.
Processing and manufacturing: silicone mold, pad printing glue head.
