Liquid Silicone Rubber
Two-component liquid silicone for injection molding and liquid-injection processes.

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.
| Parameter | What we need from you |
|---|---|
| Hardness (Shore A) | Target hardness and the tolerance you can accept |
| Viscosity / flow behaviour | Wall thickness, flow length and gate design |
| Curing system | Addition cure or another system, plus cure temperature |
| Pot life / working time | Cycle time available between mixing and injection |
| Tensile and tear strength | Mechanical duty the part will see in service |
| Elongation at break | Whether the part flexes, stretches or stays rigid |
| Compression set | Sealing duty and the temperature it operates at |
| Colour and translucency | Colour reference, or whether the part stays translucent |
| Service temperature range | Continuous and peak operating temperatures |
| Compliance requirements | Any 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.
