Why using LSR rubber

Liquid silicone rubber (LSR) is liquid silicone with very low viscosity that can be moulded by injection.

“Liquid” silicone is so called to differentiate LSR from high consistency paste silicone products.
LSRs are polymerization systems.

In its raw un-polymerized form, LSR consists of two parts of liquid mixed together (polymerization starts by mixing part A and part B) and heated to accelerate the polymerization process.

The advantages of using LSR products: they improve manufacturing efficiency

The product is completed immediately after moulding

Higher productivity per hour

Energy savings

LSR: properties and possible applications

Note that liquid silicone rubber injection moulding is the opposite of thermoplastic moulding: a room-temperature liquid silicone compound is injected and polymerized in a hot mould instead of plastic pellets being melted in a hot liquid forced into a cooled mould.

Performance properties and fast polymerization cycles make LSR rubber a good choice for small moulded parts. Unlike most thermoplastic elastomers (TPR and TPE), LSR remains flexible and elastic at low and high temperatures.

Liquid silicone products are used in a variety of industries and applications. The major ones are for the medical and food industries, where LSR silicone is used to produce various accessories and components. Other application sectors include automotive (automotive seals, coating and sealing for airbags), electrical (coating for electrical insulators, keypads for electronic devices), and furniture (textile coatings and LED lighting).
