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.
Better weather resistance and environmental adaptability, such as resistance to ultraviolet, high and low temperature, humidity, salt spray, etc., is not easy to age and become brittle, to ensure that the long-term use of the process to maintain the structural integrity and stability of the appearance, whether in extreme temperatures, humidity or chemical contamination 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 materials, can provide excellent electrical insulation performance, effectively prevent current leakage, to protect the user's safety, to avoid the risk of electric shock.
The heat distortion temperature is higher than that of ordinary PVC materials, which can be adapted to the more severe high-temperature environment. Risks.
Lightweight and cost-effective, relative to other explosion-proof materials (such as metal) lightweight advantage, reduce the overall weight, both to meet the performance requirements and economical, and help to reduce the overall manufacturing costs and end-user procurement costs.
Machinability and design flexibility, easy injection and extrusion molding, and the ability to design and accurately process complex structures to meet diverse 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 high-temperature, high-performance alloys exhibit key properties such as flame 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.
