Description

Liquid silicone rubber gasket is made of liquid silicone rubber by LSR injection molding, installation and disassembly are very convenient, because it is elastomer, sealing effect is also good, widely used in the need of elastic sealing electronic products, medical equipment and other fields.

Liquid silicone gasket & liquid rubber gasket silicone gasket seal gasket with high temperature, aging resistance, soft, ozone resistance, weather resistance, high and low temperature resistance and other properties, color can be done in a variety of hardness is generally between 30-70 degrees, high temperature -40 degrees to 300 degrees, and conventional organic elastomer, silicone rubber is particularly easy to process and manufacture.Silicone rubber is easy to flow, so it can be molded, rolled and extruded under the condition of low energy consumption.Easy to process means high production efficiency.

It is safer, more environmentally friendly, more transparent, more time - saving, more labor - saving and more efficient than vulcanized silicone rubber gaskets.

Liquid silicone rubber - LSR is very low viscosity silicone that can be intended for use in liquid injection molding (LIM) equipment or cast into silicone rubber sheets. LSRs are generally injection molded or cast while gum based silicones are typically compression molded. It offers high thermal stability and flexibility at low temperatures, high transparency and is easily colored.

Liquid Silicone Rubber has good Mechanical Properties:low compression set, good elongation, high tear and tensile strength etc.

Liquid Silicone Rubber Durometer: hardness is from 5 Shore A to 80 Shore A

Liquid silicone can withstand a wide range of high/low temperature extremes, which offers high thermal stability and flexibility at low temperatures. Working temperature is from -40℃ to 230℃.

Liquid Silicone Rubber Biological Compatibility (Biocompatibility): good food, water and medical contact. LSR is a very safe application for human body.

Under extensive testing, liquid silicone rubber has demonstrated superior compatibility with human tissue and body fluids. In comparison to other elastomers, LSR is resistant to bacteria growth and will not stain or corrode other materials.

LSR is inorganic substance, which is clean, plasticizer-free, tasteless and odorless. LSR is not only waterproof, but also chemical resistant, such as oxidation acids and alkali resistant.

LSR is resistant to bacteria growth, which do not stain or corrode other materials and also burns to form water vapor and carbon dioxide, no halogens, no toxins etc.

LSR can be sterilized by steam antoclaving, ethylene oxide, gamma, e-beam etc.

LSR can meet all food grade and medical requirements or certifications, like USP Class VI, FDA 21 CFR 177.2600, BfR XV etc.

Liquid silicone rubber electrical properties: excellent insulating property. Some elastomeric LSR is flame proof as which includes fire retardant.

LSR Transparency and Pigmentation: LSR is platinum-cured and transparent silicone which is more transparent than solid silicone. Liquid silicone rubber can be mixed with pigment to produce colorful LSR injection molded products.

Liquid Silicone Rubber Injection Molding

Liquid silicone rubbers are supplied in barrels. Because of their low viscosity, these rubbers can be pumped through pipelines and tubes to the vulcanization equipment.

Liquid silicone rubber is a high purity platinum cured silicone with low compression set, great stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is a must. Due to the thermosetting nature of the material, liquid silicone injection molding requires special treatment, such as intensive distributive mixing, while maintaining the material at a low temperature before it is pushed into the heated cavity and vulcanized.

Liquid silicone rubber molding involves room temperature compounds mixed and pumped into a hot mold. Tooling designs are simplified as liquid silicone rubber flows readily into very thin cross sections, tight radii and thick / thin features. Tooling surfaces do not have to be highly polished, and draft angles are not required to facilitate removal of the finished component from the tooling.

When the cure cycle is complete, the molded silicone gasket (LIM gasket) can be removed without concern of distortion or tearing as the silicone is fully cured. (TPRs and TPEs would require ejector pins and draft angles designed into the molds). Call to see samples of liquid silicone injection molding items containing undercuts, straight walls and similar design features that were produced from molds designed to utilize the unique properties of LSR.
