Liquid Silicone Rubber vs High Consistency Rubber

Silicone rubber is a thermoset with a backbone of alternating silicone and oxygen atoms with methyl or vinyl side groups. There are two types of silicone rubber: solid and liquid. The basic structure of the two types of silicone rubber is the same, but curing and processing are radically different.

Breakthrough inventions are the result of ideas, guts, perseverance, and dedication. They are the engine of the future economy. Liquid Silicone Rubber (LSR) is at the cutting edge of these breakthroughs. It allows for the creation of products impossible to make before. All of this is made possible thanks to its unique properties and the endless number of applications. Additionally, liquid silicone rubber is efficient and environmentally friendly. In other words, thanks to liquid silicone rubber, the future of innovations is looking bright.

Liquid Silicone Rubber and Electricity

Colored telecommunications cables and wires

Ceramic and glass have long functioned as the material of choice for medium and high-voltage electrical applications, high-voltage insulators and lightning arresters. These materials have good resistance to electrical stress as well as outdoor exposure without suffering significantly from deterioration. The transmission/distribution industry and international standard bodies have thoroughly discussed the advantages and disadvantages of these materials. Their shortcomings include contamination and the inability to handle certain stresses. These concerns have led to significant innovations in material science, especially as it relates to insulative materials and silicone rubber’s electrical conductivity.

Determination of Cure Kinetics of Liquid Silicone Rubber Using DSC Data

Multiple scanning rates were used to gain insight into the effect of time and temperature on the curing reaction of LSR and HCR systems. Properties of peak temperature, heat of reaction, and extent of reaction are obtained.

The Benefits of Two Shot Injection Molding


The compression and transfer molding process, using plastic and high consistency rubber (HCR) as raw materials, was once the dominant manufacturing process in medical, aerospace, electrical, construction and industrial applications. In recent years, however, Liquid Silicone Rubber (LSR) 2-Shot injection molding has been the manufacturing process of choice across a range of industries for the fabrication of molded parts. The LSR 2-Shot molding process enables manufacturers to produce parts in a wide range of sizes and technical configurations, one of the many advantages 2-Shot injection molding has over compression and extrusion molding.
