Features:
Liquild silicone rubber - RH6250, it has the characteristics of
high transparency, high strength, good resilience, small
deformation value, yellowing resistance and aging resistance.
Liquid Silicone Rubber for general purpose applications.
Producing quality parts rapidly is essential in the LSR molding
market. Liquid injection molding provides the most efficient and
economically viable process using Liquid Silicone Rubber (LSR).
Elkem Silicones offers a robust general purpose product range of
LSR materials including durometers from 01-70 Shore A. These
materials are specifically designed with a fast cure and excellent
mold release as well as excellent physical and mechanical
properties.
Liquid Silicone Rubber (LSR) is a two-part catalysis-cured
thermoset elastomer, we normally inject LSR materials into mold
cavities to produce final silicone parts. This material provides
properties not obtainable with TPE. Therefore, LSR is very
versatile in elastomer industry, it is widely applied in various
industries from consumer parts to medical devices.
Application:
Suitable for the production of food grade products such as baby
pacifiers, baby bottles, bottle tableware, baby toys, series
products, etc.

FAQ
What is silicone rubber?
Silicone rubber is a synthetic elastomer made from silicon, oxygen,
carbon, and hydrogen. It possesses unique properties such as
flexibility, temperature resistance, electrical insulation, and
chemical resistance, making it suitable for various industrial and
commercial applications.
What are the advantages of silicone rubber?
Silicone rubber offers several advantages, including high and
low-temperature resistance, flexibility, excellent sealing
properties, chemical resistance, electrical insulation, UV and
weather resistance, biocompatibility, and ease of processing.
What are the common applications of silicone rubber?
Silicone rubber is used in a wide range of applications, such as
sealing and gasketing, electrical and electronic components,
automotive parts, construction and architecture, medical and
healthcare products, industrial equipment, and food and beverage
industry applications.
Can silicone rubber withstand high temperatures?
Yes, silicone rubber exhibits excellent heat resistance and can
withstand high temperatures without significant deformation or
degradation. It can typically withstand temperatures ranging from
-50°C to 250°C (-58°F to 482°F) depending on the specific
formulation.
Is silicone rubber safe for medical applications?
Silicone rubber is known for its biocompatibility and is commonly
used in medical and healthcare applications. It is non-toxic and
does not cause adverse reactions when in contact with biological
