Cured silicone rubber with flame retardant, a single component, room temperature curing, high temperature, environmental protection and so on. Is the power adapter, Condensation Cure Silicone Rubber charger and switching power supply and other components of all products, bonding, fixing, insulation, sealing the best choice, reduce costs and improve efficiency.
Characteristics of cured silicone rubber:
1. Temperature characteristics
C - C bond is composed of silicon - oxygen (Si - O) bond as the main chain structure. The bond energy of C - C bond is 82.6 kcal / mole, and the bond of Si - O bond is 121 kcal in organic silicon / Mole, Condensation Cure Silicone Rubber so the thermal stability of silicone products, high temperature (or radiation exposure) molecules of the chemical bond does not break, not decomposition. Silicone can not only high temperature, Condensation Cure Silicone Rubber but also low temperature, can be used in a wide temperature range.
2. Electrical insulation performance
Cured silicone rubber has good electrical insulation properties, its 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.
Cured silicone rubber is 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-UV additive to the sealant without the addition of weathering additives Silicone sealants are exposed to outdoor long-term weather conditions do not crack does not shrink, Condensation Cure Silicone Rubber 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 recipe can get 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, Condensation Cure Silicone Rubber this feature in various industrial areas to promote the application is very important.
Cured silicone rubber properties
Fast curing: the product dry time is short (≤ 10min), deep curing fast, is conducive to fast bonding.
After curing the adhesive layer is elastic body; after the release of alcohol substances, the vast majority of metal without corrosion;
Extruded, suitable for machine dispensing. Small molecular content of less than 300ppm; Condensation Cure Silicone Rubber excellent weather resistance, moisture resistance, heat resistance; good electrical insulation properties.
Excellent bonding properties, for most metals and plastics, ceramics and glass have good adhesion.
Excellent flame retardant performance, through the UL94 V0 certification (UL FileNo.E343835); fully comply with the EU ROHS directive requirements.
Instructions for use
