Key Properties of Silicone Rubbers
The strong Si-O chemical structure and high bond energy give Si Elastomers their unique performance properties. Several benefits of silicone rubbers include:
- Wide service temperature range – excellent thermal and thermoxidative resistance (-Si-O-Si- binding energy is higher than C-C bonds)
- Excellent resistance to attack by oxygen, ozone and sunlight
- Readily resistant to electromagnetic and particle radiation (UV, alpha, beta and gamma rays)
- Excellent non-stick and non-adhesive properties
- Low toxicity
- flexible at low temperatures due to their low glass transition temperature(Tg).
- Optical transparency
- Good excellent insulation properties
- Low chemical reactivity
- High bio-compatibility
- Excellent mechanical properties (high tear strength, high elongation
