The Cured Silicone Rubber Has Heat Resistance

Jun 26, 2017

Curing silicone rubber Features: Fast curing: the product dry time is short (≤ 10min), deep curing fast, is conducive to fast bonding. 

After curing the adhesive layer is elastomer; after curing the release of alcohol substances, the vast majority of metal corrosion;

Extruded, suitable for machine dispensing. Small molecular content of less than 300ppm;  excellent weather resistance, moisture resistance, heat resistance; good electrical insulation properties.

Excellent bonding properties, for most metals and plastics, Condensation Cure Silicone Rubber ceramics and glass have good adhesion. 

Excellent flame retardant performance, passed the UL94 V0 certification (UL FileNo.E343835); fully comply with the requirements of the EU ROHS directive.

Characteristics of cured silicone rubber:

1. Temperature characteristics

Silicone products are silicon - oxygen (Si - O) bonds as the main chain structure, C - C bond bond energy of 82.6 kcal / mole, Si - O bond in the organic silicon for 121 kcal / Mole, so the thermal stability of silicone products, high temperature (or radiation exposure) molecular chemical bonds do not break, Condensation Cure Silicone Rubber not decomposition. Silicone is not only high temperature, but also low temperature, can be used in a wide temperature range.

2. Electrical insulation performance

Silicone products have good electrical insulation properties, the dielectric loss, withstand voltage, arc resistance, corrosion resistance, Condensation Cure Silicone Rubber volume resistivity and surface resistance coefficient are among the best in the insulation materials, and their electrical performance by the temperature and frequency The impact is very small. Therefore, they are a stable electrical insulation material, Condensation Cure Silicone Rubber is widely used in electronics, electrical industry. Silicone in addition to excellent heat resistance, but also has excellent water repellency, which is the use of electrical equipment in the wet conditions with high reliability protection.

3. Weatherability

Silicone products are the main chain of - Si - O -, no double bond exists, it is not easy to be UV and ozone decomposition, with excellent resistance to ozone, antioxidant atoms and antioxidant plasma and other characteristics. These features are not available with many organic polymers, Condensation Cure Silicone Rubber so when a weathering sealant is formulated with a common organic polymer as the main polymer, it is necessary to add an antioxidant or anti-ultraviolet additive to the sealant without the addition of weathering additives Silicone sealant has long been exposed to outdoor weather conditions do not crack does not shrink, the service life of up to several decades. Their excellent durability Weathering Aging avoids additional work such as frequent replacement or maintenance, which reduces overall costs and costs.


Cured silicone rubber can be formulated into a wide range of products with a wide range of viscosity and rheology. After debugging the formula can be obtained low viscosity self-leveling products, Condensation Cure Silicone Rubber can also be prepared with a good paste and good thixotropy silicone sealant. Paste thixotropic products in the vertical surface of the construction will not produce flow or sagging phenomenon, this feature in various industrial areas to promote the application is very important.
