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 UV resistance, high and low temperature resistance, heat and humidity resistance, salt spray resistance, etc., is not easy to aging and become brittle, to ensure that in the long-term use of the process of structural integrity and appearance stability, whether in extreme temperatures, humidity or chemical pollution environment can work reliably. Maintain structural integrity and appearance stability in the long-term use of the process, whether in extreme temperatures, humidity or chemical pollution environment can work reliably, the stability of this all-weather This all-weather stability is the key requirement for outdoor materials.
Excellent UV resistance, long-term exposure to sunlight is not easy to aging, discoloration or embrittlement, to ensure the consistency of the color and long-lasting durability of the material, maintain the beauty of It ensures color consistency and long-lasting durability of the material, maintains the beauty and reduces the maintenance cost.
Mechanical strength and impact resistance, with sufficient mechanical strength and good impact toughness, able to resist the physical impact of daily use, compared with metal or wooden Compared with metal or wood, it has higher elasticity and impact resistance, and can resist accidental impacts without being easily damaged, which can reduce the replacement and maintenance needs caused by external forces.
Lightweight and cost-effective, with lightweight advantages over other outdoor materials (metal or wood), reducing overall weight to meet performance requirements while being cost-effective. Beneficial, conducive to reducing overall manufacturing costs and end-user procurement costs.
Processability and design flexibility, easy injection or extrusion molding, complex structures can be designed and accurately processed to meet diverse, customized needs. The design and precise processing of complex structures can be carried out 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 outdoor PVC high-performance materials demonstrate fire retardancy, weather resistance, high mechanical strength, light weight, cost-effectiveness, and a high degree of efficiency. The key characteristics of LESHENG's high performance PVC materials for outdoor applications, such as fire retardancy, weather resistance, mechanical strength, light weight, cost effectiveness and processability, form a solid basis for choosing our materials as the ideal choice.
