Better fire retardant performance, not easy to burn and can inhibit the spread of flame, to ensure safe and stable operation in high temperature environments, reduce the risk of fire.
Excellent weather resistance and environmental adaptability, such as resistance to ultraviolet rays, high and low temperatures, humidity and heat, salt spray, etc., is not easy to age and become brittle, to ensure that the long-term use of the process to maintain the integrity of the structure and the appearance of the stability of the environment, whether it is in the extreme temperature, humidity, or chemical pollution environment can work reliably.
Mechanical strength and impact resistance, with sufficient mechanical strength and good impact toughness, able to resist the physical impact of daily use, to protect the internal electronic components from damage, to ensure that a certain degree of impact can still maintain normal function.
Electrical insulation performance, excellent insulating material, can provide excellent electrical insulation performance, effectively prevent current leakage, to protect the user's safety, to avoid the risk of electric shock.
Excellent heat deflection temperature, much higher than ordinary PVC materials, can be adapted to more severe high temperature use environment.
Lightweight and cost-effective, lightweight advantage over other materials (e.g., metals), reducing overall weight, both to meet performance requirements and economical, contributing to the reduction of overall manufacturing costs and end-user procurement costs.
Processability and design flexibility, easy extrusion molding, design and precise processing of complex structures to meet diversified and customized needs.Good paintability, according to the application scene or customer requirements for color mixing and surface treatment, to enhance the aesthetics and brand recognition.
In summary, LESHENG's CPVC high-performance materials exhibit key characteristics such as fire retardancy, weather resistance, high mechanical strength, good electrical insulation, light weight, cost-effectiveness, and processability, which together form a solid basis for choosing our materials as the ideal choice.
