Two-component liquid silicone for injection molding and liquid-injection processes.

Liquid Silicone Rubber

About this material

Liquid silicone rubber (LSR) is supplied as a two-component system for injection molding and liquid-injection molding. Because it flows into the tool rather than being shaped by pressure alone, the material discussion centres on flow behaviour, cure speed and how the part will be demoulded.

What this category covers

  • Two-component A/B systems for injection molding
  • Low-viscosity grades for thin walls and fine detail
  • Addition-cure systems for fast, clean cycles
  • Translucent, coloured and pigmented options

Typical applications

  • Injection-molded seals, gaskets and O-rings
  • Keypads, buttons and soft-touch parts
  • Medical tubing and fluid-handling components
  • Overmolding onto plastic or metal inserts
  • Infant care and consumer products

What we confirm before quoting

These are the points that decide the grade. Sending them together shortens the first reply considerably.

ParameterWhat we need from you
Hardness (Shore A)Target hardness and the tolerance you can accept
Viscosity / flow behaviourWall thickness, flow length and gate design
Curing systemAddition cure or another system, plus cure temperature
Pot life / working timeCycle time available between mixing and injection
Tensile and tear strengthMechanical duty the part will see in service
Elongation at breakWhether the part flexes, stretches or stays rigid
Compression setSealing duty and the temperature it operates at
Colour and translucencyColour reference, or whether the part stays translucent
Service temperature rangeContinuous and peak operating temperatures
Compliance requirementsAny standard the finished part must be tested against

Values below are the parameters we confirm for every order. Exact figures are grade-specific and are confirmed against your application before quoting — no generic numbers are published here.

Information to include in your inquiry
