WEIFANG POLYGRAND CHEMICAL CO.,LTD.

Has excellent abrasion resistance in a wide range under operating conditions, very good dimensional stability, high mechanical strength, stiffness and hardness. It is used in aviation, atomism, chemistry, automotive and electrotechnical industry as well as in all types of military equipment, in the manufacture of gears, valve seats and bearings

Is a material belonging to the group of highperformance thermoplasts. It has the best heat resistance among plastics with technical use. It also has very high chemical resistance. It is insoluble in all known solvents and resistant to weather conditions. It is characterized by the lowest coefficient of friction, as well as excellent insulation and the lowest dielectric coefficient. It is used in the construction of specialized equipment, in the construction of machines, pumps, in water installations, chemical installations, medicine, food industry, in thermal technology.

Is characterized by high flexibility, durability and UV resistance. The material is easily subjected to mechanical machining and thermoforming, it is a fully transparent material whose very important feature is high impact resistance. The polycarbonate panels are wellpermeable to light and have a significant stiffness combined with low mass. Due to its properties, it is often used in the engineering and construction industries

Due to high surface hardness and low surface abrasiveness, it is characterized by good slip and good resistance to friction, does not dissolve and does not swell in all used solvents, in fuels and mineral oils. It is most often used for the production of precision machine parts, such as gears, worm gears, bushes, etc
