With the rapid development of LED industry in recent years,the technology applicated in LED industry make a great achievement。Silicone used in LED would be a successful example。 LED silicone is the general term of the silicone material of LED optoelectronic industry .As the ozone resistance ability is so weak that colloid turn yellow easy , and with resitance to atmospheric aging and anti-aging UV of silicone material , Epoxy resin in the high-end product applications have been replaced by LED silicone material. 一、performance and characteristics:

Compared with other polymer materials, the most outstanding performance of the LED silicone products are:

1、Resistance to temperature characteristics : The temperature characteristics of high-power LED silicone not only high temperature, low temperature, can be used in a wide temperature range .Whether or chemical properties physical and mechanical properties, temperature dependence is very small. 2、Weather resistance 3、Electrical insulation properties LED silicone products have good electrical insulation properties : dielectric loss resistance, voltage , resistance, arc , corona resistant , volume resistivity and surface resistivity ,etc. are among the best in the insulating materials and their electrical performance is affected by temperature and frequency little effect. Therefore, they are a stable electrical insulating materials, are widely used in electronics and electrical industry .LED silicone in addition to excellent heat resistance, excellent water repellency, which is highly reliable protection of electrical equipment in wet conditions. 4、Physiologically inert The polysiloxane compound is a known active compounds :They are extremely resistant to biological aging , and animal body without rejection , and has better anti-clotting properties。二、Main applications The chip fixed commonly known as a solid crystal plastic、LED mixed witn phosphor silicone、filling LED silicone。Used in LED applications LED silicone purpose is to waterproof, in order to achieve the internal circuit of the protection products , There are LED display PCB board to protect the black potting silicone、Potting silicone seal on the LED lamps that we common know 。
