(I) Excellent elasticity in a wide temperature range
One of the outstanding characteristics of phenyl silicone rubber is that it can maintain good elasticity in a very wide temperature range. From the extremely cold environment of -100℃ to the extremely hot temperature of +300℃ (some high phenyl content products can even withstand 400℃), it can maintain a stable elastic state. Compared with traditional rubber materials, its temperature application range has been greatly broadened, greatly enhancing its applicability under different climate and working conditions. For example, in the application of sealing components around polar scientific research equipment and high-temperature industrial furnaces, phenyl silicone rubber can reliably play a sealing and buffering role to ensure the normal operation of the equipment.

(II) Excellent weather resistance and chemical stability

In complex natural and chemical environments, phenyl silicone rubber exhibits excellent tolerance. It is not prone to aging and degradation under long-term exposure to ultraviolet rays, ozone, moisture, and various chemical substances, which effectively guarantees the service life of the product. Taking the insulating protective cover of outdoor high-voltage electrical equipment as an example, after being made of phenyl silicone rubber, it can withstand years of wind, sun, rain, frost, and industrial waste gas erosion, and still maintain good insulation and physical and mechanical properties, reducing the frequency of equipment maintenance and reducing operating costs.

(III) Low compression set and high dimensional stability
When subjected to long-term pressure or high temperature, the compression set rate of phenyl silicone rubber is extremely low, which means that it can always maintain precise shape and size. In application scenarios with extremely high requirements for sealing and dimensional accuracy, such as sealing gaskets of aircraft engines and sealing elements of high-end hydraulic equipment, this feature enables the sealing structure to work stably for a long time, avoiding failures such as leakage caused by material deformation, and providing solid guarantee for the efficient and safe operation of the equipment.

(IV) Excellent electrical insulation performance
In the field of electronics and electrical, phenyl silicone rubber stands out with its excellent electrical insulation performance. It has high insulation resistance, stable dielectric constant, and minimal fluctuation in electrical performance under different humidity and temperature conditions. Whether in the potting protection of integrated circuits, insulation treatment of cable connectors, or in the manufacture of insulation components for high-frequency communication equipment, it can provide reliable insulation protection to ensure stable operation of electronic equipment and accurate signal transmission.
