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 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 contamination of the 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 ensure that a certain degree of impact can still maintain normal function.
Comply with medical grade use, can pass the biocompatibility test to ensure safe and harmless contact with human tissues, non-toxic, lead-free, low migration, will not cause allergic reactions, to ensure that in the process of medical use will not be contaminated with medication or affect the patient's health, suitable for all kinds of medical equipment and supplies.
Compliant with food grade contact use, it can be used in kitchenware, refrigerator compartments, bathroom supplies and other environments.
Machinability and design flexibility, easy injection or 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 transparent PVC high-performance materials exhibit key characteristics such as fire retardancy, weather resistance, high mechanical strength, light weight, cost-effectiveness and processability, which together form a solid basis for choosing our materials as the ideal choice.
