Phenyl vinyl silicone oil

USi-OP40

Features

Vinyl-terminated methyl phenyl silicone oil is mainly used in the preparation of additive liquid silicone rubber, because of containing phenyl functional groups, improve the resistance to high and low temperature, radiation resistance. It is designed for the manufacture of high-power high-refractive-light-emitting devices with silicone encapsulated plastic, optoelectronic, electronic and microelectronics industries. It is mainly used in the manufacture of high-power, high-power, Lens and the user to develop other uses, the product after curing the film soft and hard adjustable, high refractive index, good light transmission, with a strong solvent resistance, water resistance, ablation and radiation resistance, but also has High temperature performance, no sticky and other advantages. The products made with anti-aging, anti-ultraviolet performance and long-term use of non-yellowing of the excellent characteristics. Its structure is as follows:

(CH2 = CH2) (CH3) 2SiO [(CH3) 2SiO] m [(C6H5) 2SiO] nSi (CH3) 2 (CH2 = CH2)
