Shin-Etsu KE Series Silicone Rubber is a range of high-temperature vulcanizing (HTV) solid silicone rubbers pre-compounded with reinforcing fillers, so manufacturers only need to add a curing agent and process. The range offers multiple hardness grades and specialty properties such as oil resistance, flame retardancy and electrical conductivity, meeting diverse requirements for engineered rubber components.
| Property | Value |
|---|---|
| Hardness | 30–80 Shore A |
| Tensile strength | 7–10 MPa |
| Elongation at break | 300–600% |
| Press cure | 170 °C for 10 minutes |
| Post-cure | 200 °C for 4 hours |
Re-mill the compound on a two-roll mill before processing to restore plasticity, then add the peroxide curing agent at the recommended ratio. Avoid contamination from organic rubber, sulfur or amines, as these can inhibit cure. Post-curing removes peroxide decomposition by-products, reducing odor and improving compression set.
Thoroughly clean mills and molds when switching from organic rubber to silicone to avoid tacky surfaces and incomplete cure.
Contact the technical team at AMS Vietnam for advice on hardness grade and curing agent selection, and for trial runs on your actual molds.
