Liquid Silicone Rubber — Technical Data
Two-component liquid silicone for injection molding and liquid-injection processes.
Specification parameters
The table lists every parameter we confirm for this material category. Figures are grade-specific, so the “confirmed per grade” column is filled in against your application rather than published as a generic range.
| Parameter | Typical value | Notes |
|---|---|---|
| Hardness (Shore A) | Confirmed per grade | Target hardness and the tolerance you can accept |
| Viscosity / flow behaviour | Confirmed per grade | Wall thickness, flow length and gate design |
| Curing system | Confirmed per grade | Addition cure or another system, plus cure temperature |
| Pot life / working time | Confirmed per grade | Cycle time available between mixing and injection |
| Tensile and tear strength | Confirmed per grade | Mechanical duty the part will see in service |
| Elongation at break | Confirmed per grade | Whether the part flexes, stretches or stays rigid |
| Compression set | Confirmed per grade | Sealing duty and the temperature it operates at |
| Colour and translucency | Confirmed per grade | Colour reference, or whether the part stays translucent |
| Service temperature range | Confirmed per grade | Continuous and peak operating temperatures |
| Compliance requirements | Confirmed per grade | Any standard the finished part must be tested against |
Packaging, storage and documentation

Frequently asked
Can you match a hardness we already use?
Send the target Shore A value and the tolerance you work to. Hardness is confirmed against the specific grade rather than assumed from a catalogue range.
Do we need to send a sample part?
A sample part or a drawing is the fastest way to align on wall thickness, flow path and demoulding. It is not mandatory but it removes a lot of back-and-forth.
How is colour handled?
Provide a colour reference — a physical sample, Pantone or RAL code — and confirm whether the part stays translucent. Colour paste is selected to match the base and cure system.
