·Extrusion of hoses, drinking water pipe pressure pipes, solid rubber strips, special-section sealing strips, plates, calendered sheets, etc.
In the field of EV electric vehicles, silicone rubber cable materials are favored for their excellent performance.
High and low temperature resistance：Silicone rubber cables can maintain stable performance under extreme temperature conditions, with a wide temperature range from -60°C to +200°C, suitable for applications in high temperature environments such as electric vehicle battery packs and charging piles.
Electrical insulation: Silicone rubber has excellent electrical insulation properties, ensuring the safety and reliability of cables when transmitting electrical energy, and reducing the risk of failure due to insulation failure.
Chemical corrosion resistance: Silicone rubber has good resistance to a variety of chemicals such as acids, alkalis and oils, and is suitable for use in electric vehicle components with complex chemical environments.
Softness and ease of installation: Silicone rubber cables are soft and easy to install and wire, especially when the space inside the vehicle is limited, soft cables are easier to lay out.
Environmentally friendly and sustainable: Silicone rubber is an environmentally friendly material that can be recycled and reused. It is relatively environmentally friendly during production and use, and meets the requirements of sustainable development.
Aging resistance and durability: Silicone rubber cables have good aging resistance, stable performance under long-term use, reduced replacement frequency, and reduced maintenance costs.
Tear strength: Silicone rubber cables have high tear strength and can withstand mechanical stress during vehicle operation.
Large current carrying capacity: Silicone rubber cables allow for greater current carrying capacity, can cope with the requirements of long-term full-load operation, and are suitable for high-current applications such as electric vehicle batteries and motors.
Flame retardant properties: Silicone rubber can be improved by adding flame retardants to improve its flame retardant properties to meet the high safety requirements of electric vehicles.
These advantages make silicone rubber cable materials an ideal choice in the field of EV electric vehicles, especially in new energy vehicles that require high performance, high reliability and environmental protection.
