Liquid Silicone Rubber Properties

Main properties of liquid silicone rubber.

Liquid silicone rubber properties. Properties of liquid silicone rubber 1. Unlike most thermoplastic elastomers tprs and tpes lsr remains flexible and elastic down to 58 f and retains its properties up to 392 f. Liquid silicone rubber liquid silicone rubber contains polymers of lower molecular weight and hence shorter chains. Silicone rubber is an elastomer composed of pdms or silicone which is itself a polymer containing silicon together with carbon hydrogen and oxygen.

This heat cured elastomer is an excellent solution to consider if you re looking for highly optical clarity combined with long term durability in harsh environment high. Liquid silicone rubber is always addition curing platinum cat alyzed and is marketed by wacker as elastosil lr where lr stands for liquid rubber lsr grades are sup plied as 2 component. Even at extreme temperatures the thermal conductivity. Silicone rubbers are widely used in the medical food military aerospace and consumer industries.

This is the defining characteristic of silicone. Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost. Stable under extreme temperatures. It also has better flow properties.

Compared to other elastomers molded silicone can withstand a wide range of high low temperature extremes for example silastic lsr by dow corning for continuous use can remain stable through temperatures ranging from 60 c to 180 c. Liquid silicone rubber has good elongation high tear and tensile strength excellent flexibility and a. Silicone rubber compounds have characteristics of inorganic and organic materials and they offer a number of advantages in comparison to other rubbers. Silicone rubber has a variey of uses and formulations which make it a very useful and popular component.

Liquid silicone rubber is a low viscosity and high purity thermoset elastomer maintaining mechanical properties over a wide range of temperatures from 50 c to 250 c. Within this range the material retains its shape and other physical properties. Here some of the most important properties of silicone are presented and explained. Fully cured silicone rubber has a normal operating temperature of 100 c to 300 c.

It is a mainstay in healthcare manufacturing automotive component manufacturing electronics and consumer products gaskets and other hardware and many other markets. Performance properties and fast cure cycles make liquid silicone rubber a good choice for small molded components.
