Solid Silicone Rubber — Technical Data
High-consistency solid silicone for compression molding, transfer molding and extrusion.
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 acceptable tolerance |
| Mooney viscosity | Confirmed per grade | How the compound needs to flow in your tool or die |
| Curing system | Confirmed per grade | Peroxide or addition cure, and your process temperature |
| Compression set | Confirmed per grade | Sealing duty and operating temperature |
| Tensile strength | Confirmed per grade | Load the part carries in service |
| Tear strength | Confirmed per grade | Whether the part is cut, clamped or flexed repeatedly |
| Elongation at break | Confirmed per grade | How much the part deforms before failing |
| Density | Confirmed per grade | Weight targets and compound costing |
| Service temperature range | Confirmed per grade | Continuous and peak operating temperatures |
| Colour | Confirmed per grade | Colour reference or natural/translucent requirement |

Frequently asked
How do we choose between peroxide and addition cure?
It comes down to your process and the part. Addition cure is typically used where a clean, fast cycle matters; peroxide cure suits other processing routes. Tell us your process and we confirm which system fits.
Can you supply extrusion grades?
Yes. Describe the profile, the die and the downstream handling, and the compound is selected to suit extrusion rather than moulding.
What determines the Mooney viscosity we need?
Mainly the tool or die geometry and how the compound is fed. Share your equipment and target cycle and it is confirmed from there.
