Silicones used for Liquid Injection Moulding Procedures (LIM) are usually standard two component liquid silicones. LSR (Liquid Silicone Rubbers) crosslink with heat, have a 1:1 mix ratio and use a polyaddition, platinum catalyst.
Due to the unique processing properties, LSR’s are suited for numerous industrial applications across many industries. They are the ideal components for producing complex shapes.
Because of their biocompatibility, odourless nature and good haptical properties, silicones are the first choice for many medical and orthopaedic products. Their high temperature stability, good insulating properties and low compression set are advantageous for the industrial processing of seal rings, plug-in connectors and membranes. Silicones crosslink without any by-products and when combined with injection-moulding, these silicones enable fast, high volume production of tiny components with complex shapes and fine detail.
LSR injection mouldings are more complex and more expensive than thermoplastic injection mouldings
CHT also have LSR's designed for laser marking, please visist the LSR product page for more information.
