IOTA 232 phenyl hydrogen terminator features fixed refractive index 1.500, perfectly matched with vinyl phenyl silicone resin. Cured products boast high light transmittance and excellent anti-yellowing performance under long-term high temperature, customized for LED optical encapsulation and high-transparency phenyl silicone rubber.
Phenyl structure endows finished goods with outstanding heat and weather resistance. Moderate boiling point reduces volatilization during processing to avoid bubbles. 98% high purity enables adjustable crosslink density for flexible hardness and toughness control. Great compatibility ensures uniform mixed systems. High flash point guarantees safe storage and transport with stable drum supply.
As special crosslinker for high-end optical silicone materials, it improves light transmittance and heat resistance of sealing layers for lamps and optoelectronic devices, a cost-effective substitute for imported premium phenyl crosslinkers.
