What is organic silicone ?

Characteristics of silicone
   Silicone is a synthetic, high molecular polymer to a silicon atom and an oxygen atom of the main chain structure. Constituting the main chain of silicon - oxygen structure with a strong chemical bonding, therefore silicone polymer molecules than the average organic polymers to heat, oxygen is much more stable. Although the mechanical properties of organic silicon at room temperature and other materials is insignificant, but at a high temperature and low temperature physics, mechanical performance excellence, the temperature at -60 to + 250 ℃ repeatedly alternating and its performance is not affected, thus long-term use organosilicon high polymer in this temperature region. Some of the organosilicon high polymer silicone was better under normal use up to -100 ℃ in. Also, because there are dipole interaction within the silicone molecule, it can effectively reduce the impact of a buffer and an external electric field, which is connected to the hydroxyl groups on the silicon atom has a protective effect, making it less susceptible to erosion physical factors or chemical reagents. All products made with polyorganosiloxane addition to the basic corrosion-resistant, resistant to radiation, high temperature resistance, also has a low moisture absorption, high insulation resistance, low dielectric constant, low stress, vibration, environmental protection, low toxicity, flame retardant, and repair and other characteristics. Therefore, a wide range is made of silicone adhesive sealants, encapsulants, coatings and insulation grease and other products used in various electronic devices.

Silicone materials used in automotive electronics on
   Silicones in automotive electronic devices are: adhesive and sealants, encapsulants, gels, silicone insulation coatings, thermal plastic and other materials. These materials are used to protect the engine control module, ignition and ignition module Juan, powertrain module, brake system module, emissions control module, power supply systems, lighting systems, various sensors, connectors, ... etc.

   Adhesive and sealant: used as an adhesive in the various control modules fixed on a circuit board components, or large components, such as capacitors, inductors, and the auxiliary coil are secured to prevent components due vibration and fall off, there is a fixed and damping functions. There is also used silicone bonding and sealing of the module housing, play sealed, moisture, dirt, corrosion function. The use of thermal conductive adhesive is an adhesive with both cooling function, can be used to fix a power device or adhesive bonding with the heat radiating plate in order to achieve heat dissipation. Dow Corning DC7091 various control module housing in sealing, bonding of the connector has been widely used. The engine control module circuit board and bonded aluminum shell heat between the thermal conductivity is a typical application of adhesive, thermal adhesive Dow Corning 1-9226 is very popular.
