Liquid Silicone Rubber Properties
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 properties. Performance properties and fast cure cycles make liquid silicone rubber a good choice for small molded components. This is the defining characteristic of silicone. Silicone rubber has a variey of uses and formulations which make it a very useful and popular component. Liquid silicone rubber has good elongation high tear and tensile strength excellent flexibility and a.
It is a mainstay in healthcare manufacturing automotive component manufacturing electronics and consumer products gaskets and other hardware and many other markets. As silicone rubber has exceptional noise reduction and anti vibration properties it can be formed into small components and fitted into small gaps ensuring all equipment can be protected from unwanted vibration such as overhead lockers vent ducts hatches entertainment system seals and led lighting systems. Properties of liquid silicone rubber 1. 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. Stable under extreme temperatures. Fully cured silicone rubber has a normal operating temperature of 100 c to 300 c. Silicone rubber is an elastomer rubber like material composed of silicone itself a polymer containing silicon together with carbon hydrogen and oxygen silicone rubbers are widely used in industry and there are multiple formulations.
Liquid silicone rubber is a highly versatile material and new applications for it are discovered and tested every day. 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. 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 a low viscosity and high purity thermoset elastomer maintaining mechanical properties over a wide range of temperatures from 50 c to 250 c.
It also has better flow properties. Here some of the most important properties of silicone are presented and explained. Main properties of liquid silicone rubber. Silicone rubber is an elastomer composed of pdms or silicone which is itself a polymer containing silicon together with carbon hydrogen and oxygen.
Within this range the material retains its shape and other physical properties. Silicone rubbers are widely used in the medical food military aerospace and consumer industries.
