1.Heat resistance properties
Organic silicone products based on silicone (Si - O - oxygen key chain structure, C - C key in the key for 82.6 kcal/mol, Si - O can key in the key of 121 kcal/mole in the organic silicone, so organic silicone products is high, the thermal stability of high temperature (or radiation exposure) molecular bonds do not broken, do not break down.Organic silicone is not only resistant to high temperature but also low temperature, which can be used in a wide range of temperature.Whether chemical or physical mechanical properties, the temperature changes are small.
The main chain of organic silicone products is - si-o -, no double bond exists, so it is not easy to be decomposed by uv and ozone.The organic silicone has better thermal stability than other macromolecule materials and the ability to withstand irradiation and weathering.The life of organic silicone in the natural environment can reach several decades.
3.Electrical insulating property
Organic silicone products have good electrical insulating properties, the dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity and surface resistivity of all came out on top in the insulation material, and their electrical performance is affected by temperature and frequency is small.As a result, they are a stable electrical insulating material and are widely used in electronics and electrical industry.In addition to its excellent heat resistance, organic silicone has excellent water-repellent, which is the guarantee of high reliability under wet conditions for electrical equipment.
Polysiloxane compounds are one of the least active compounds known.They are very resistant to biological aging, have no rejection of animals, and have better anticoagulant energy.
5.Low surface tension and low surface energy
Main chain of organic silicone is very smooth, the intermolecular force is much weaker than hydrocarbons, therefore, than with low molecular weight hydrocarbons viscosity, surface tension, surface energy is small, film forming ability.This low surface tension and low surface can be the main reasons for its application in many aspects: hydrophobic, foaming, foam stabilization, anti-adhesion, lubrication, glazing and other excellent properties.
