Silicone materials and technologies in LED Applica

    One thousand Beijing Optoelectronic Materials and Technology Division was established in May 2009, Beijing, Shenzhen City, one thousand Technology Development Co., a subsidiary of R & D, production and marketing in one division.

    Division is mainly engaged in the LED package of silica gel R & D, production and sales. Division has a dust-free workshop, a pilot plant, two specialized laboratories, a testing center. There is a high level of R & D team, have a good marketing group, has a solid production team. Currently, the division main products are high-power LED package with a high refractive index of the refractive index of silica gel and the general, for a fixed chip adhesive and insulation thermal conductivity of silver plastic, phosphor, etc. Packaging process while providing guidance for high-power LED package providing practical solutions to provide customers with innovative LED packaging technology.

    One thousand optical materials for the Beijing Science and Technology to provide silicone LED packaging industry packaging materials solutions that help customers LED package should be

    Challenges from the market.

    One thousand Beijing Optoelectronic Materials Science and Technology's products include LED packaging materials, gels, elastomers and resin body.

     Performance: high optical transparency; excellent resistance to ultraviolet radiation; thermal stability and strong; low water absorption rate; low ion content

     Advantages: suitable for infrared, visible or ultraviolet optical applications; for lead-free manufacturing process; with a good variety of enclosure bracket bonding substrate.

One thousand Beijing Technology and high refractive index optical material Tigong general refractive index of the AP series silicone potting agents, the wavelength of the LED applications with superior light transmission. In the LED chip packaging and protection applications, these materials provide excellent package stress relief, moisture protection and resistance to ultraviolet radiation. Physical form: medium viscosity liquids, gels formed after curing, elastomer or resin body. Special properties: transparent, refractive index of 1.41-1.53.
