What is liquid silicone rubber?

Liquid silicone rubber (LSR) is a two-part silicone-based polymer joined together by a chemical bond. It’s most commonly used to create injection molded parts for products used in industries such as automotive, food, appliances, textiles, and consumer goods.

Now we introduced the LSR into production of shower products, in order to reach a much better experience of showering.

What are the benefits of using liquid silicone rubber?

Superior heat stability
LSRs can withstand temperatures up to 180 °C with no melting or creeping. They have become a popular option for heavy-duty and automotive applications like seals and gaskets.
Low-temperature flexibility
Thermoplastic elastomers can lose their flexibility at extreme temperatures. At low temperatures, they become harder and more brittle until they eventually crack. LSRs, however, remain flexible at temperatures as low as -50 °C. They are an excellent choice for any products that need to operate in a low-temperature environment.
Aging resistance
Aging resistance is an important factor in determining the right material for your injection molding process. Cured LSR materials provide excellent resistance to UV rays, weathering, and aging. They are ideal for use in applications where long-term exposure to the elements is a concern.
Chemical resistance
Thermoplastic elastomers can resist chemicals in a broad range of applications. But they only offer chemical resistance in moderate temperature ranges. LSR offers low water absorption and excellent resistance to common chemicals even when exposed to extreme temperatures.
Low compression set
A low compression set means that materials can resist permanent deformation under a constant strain. LSRs have a very low compression set, typically in the range of 15%-20%. They are able to retain their elasticity even when compressed for extended periods of time and subjected to different temperature ranges.
Great shelf life reliability
The shelf life of liquid silicone rubber is one of the key factors contributing to the ease of use in a manufacturing environment. Most LSR products are available with a shelf life of at least one year.
Electrical resistance
Electronics manufacturers need to know that the materials they are using can resist corona discharge. LSR offers high resistance to electrical stress without impacting the conductivity of the final product. For this reason, these materials are commonly used in high-voltage applications and electrical parts.
