The performance advantages of poly(methylphenyl)siloxane vary with the adjustment of the phenyl content. The core highlights include high refractive index, biocompatibility, and weather resistance. By adjusting the phenyl ratio (typically 25%-30%), it can be adapted to different high-end scenarios. Its refractive index range is 1.480-1.515, and some phenyl conversion materials can reach 1.57. It has excellent light transmittance and also possesses environmental-friendly characteristics such as low VOC and high solid content (≥98%), and can be controlled to cure at room temperature through catalysts. 
In the electronics field, PMPS is a key raw material for LED packaging silicone and high-transparency electronic potting compound, which can ensure the stability and light transmittance of precision components, and meet the thermal management requirements of semiconductors and power electronics. In the beauty industry, it is added as a high-end raw material to lipsticks and foundation, which can enhance the luster and skin feel of the products, form a breathable protective film on the skin surface, and have both safety and comfort. In addition, its emulsion can be used for the softening treatment of textiles, giving the fabric UV resistance and high-temperature resistance properties; in the optical field, high-refractive index types can be used to prepare special optical materials. With the ability to withstand high and low temperatures and radiation, they gradually expand to high-end manufacturing fields such as medical and aerospace, and the market demand is continuously increasing.
