LSR Liquid Silicone Rubber

Share to:

LSR liquid silicone rubber is known as LSR, clear liquid silicone rubber, clear liquid silicone, or liquid food grade silicone, which is a process to produce pliable, durable parts in high volume by LSR injection machines. Liquid Silicone Rubber has been steadily gaining a foothold in many markets due to its ability to produce intricate elastomeric components with relatively short cycle times, which can save time and labor.

LSR Liquid Silicone Rubber

LSR liquid silicone rubber is known as LSR, clear liquid silicone rubber, clear liquid silicone, or liquid food grade silicone, which is a process to produce pliable, durable parts in high volume by LSR injection machines. Liquid Silicone Rubber has been steadily gaining a foothold in many markets due to its ability to produce intricate elastomeric components with relatively short cycle times, which can save time and labor.
LSR cooling system allows production of LSR parts with nearly zero material waste, eliminating trimming operations and yielding significant savings in material cost.

Clear Liquid Silicone

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.

LSR & Solid Silicone

LSR Biocompatibility
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.

Durable

LSR parts can withstand extreme temperatures, which makes them an ideal choice for components under the hood of cars and in close proximity to engines.

LSR Chemical Resistance

Liquid silicone rubber resists water, oxidation and some chemical solutions such as acids and alkali.

LSR Temperature Resistance
Compared to other elastomers, silicone can withstand a wide range of high/low temperature extremes.

LSR Mechanical Properties
LSR has good elongation, high tear and tensile strength, excellent flexibility and a hardness range of 5 to 80 Shore A.

LSR Electrical Properties
LSR has excellent insulating properties, which offer an appealing option for a host of electrical applications. Compared to conventional insulating material, silicone can perform in far higher and lower temperatures.

LSR Transparency and Pigmentation
LSR possesses a natural transparency. This attribute makes it possible to produce, colorful, custom, molded products


Liquid Silicone Rubber Injection Molding & Processing

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

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.
