Anti-corona Rubber Raw Materials

Anti-corona rubber raw materials build a stable structure at the molecular level through a special formulation system, which can resist erosion caused by corona discharge. Their corona resistance performance far exceeds that of ordinary rubber. This material possesses excellent insulation properties. Even under high voltage and strong electric field conditions, it can effectively block leakage currents and maintain a stable and reliable insulation state. Meanwhile, it has outstanding aging resistance characteristics. It can withstand the harsh tests of ozone, ultraviolet rays, and temperature fluctuations generated by corona discharge for a long time without cracking, hardening, or pulverizing, and can maintain the stability of its elasticity, toughness, and physico-mechanical properties for an extended period.

Rubber components manufactured using these anti-corona rubber raw materials can resist the continuous damage caused by corona discharge from the root, preventing key components such as seals and insulating pads from failing prematurely due to corona erosion. This significantly extends their service life and reduces equipment downtime frequency for maintenance. Its excellent insulation performance builds a safety barrier for the equipment, effectively preventing the risks of electric leakage or short circuits caused by a decline in insulation, ensuring the safety of operators and the stable operation of equipment. In addition, the long-term stability of the raw material performance ensures consistent performance of the components made from it in precision applications such as corona treatment equipment, helping to maintain process stability and indirectly reducing production losses and maintenance costs caused by fluctuations in component performance.

These anti-corona rubber raw materials are specifically designed for extreme corona environments and are mainly used to manufacture special rubber components operating in strong corona fields. Typical applications include key insulating rubber parts in high-voltage motors and transformers, as well as rubber rollers and seals that directly contact high-voltage discharge areas in various corona treatment equipment (such as film surface treatment machines). They are the core materials that ensure the long-term and reliable operation of these equipment in high-voltage and high-ozone environments.
