How many kinds of plastics are there?
PC: commonly known as polycarbonate. The variety is also a transparent material, high surface hardness, scratch resistance, strong impact resistance, high strength, good weather resistance (that is not afraid of the sun). The furniture is the sunshine plate screen baffle material hollow extrusion molding. Features: high price cost, about PMMA higher than about 40%.
PMMA: organic glass (commonly known as acrylic). There are five kinds of transparent plastic material, and PMMA is one of the highest transparency, cutting when vinegar sour, easy deformation, can turn plastic soaked in boiling water. Disadvantages: easy to scratch the surface, low hardness, easy to crack when bending, the price is higher than ABS more than 20%.
PU Name: polyurethane (foam). Mainly used for handrail accessories.Name: POM steel is mainly used for wear parts such as mats, casters, door hinge, hinge and so on. The performance of wear resistance, pressure resistance, but poor dimensional stability.Name: PA nylon. Mainly used as foot, claw, wheel wear, the life of high demand place. Features: wear resistance, pressure resistance, high strength and long service life of indoor, individual models such as PA66 heat up to 2200, is easy to change, easy to break the drying performance, poor weather resistance in the sun.
Name: ABS engineering plastics, can be used for connecting piece, seat back, seat board, it is able to perform plastic electroplating (water plating) the main raw material.PP: the name for polypropylene, five-star pin, handrails, floor mats and high strength is not necessary connections. Disadvantages: poor wear resistance and low surface hardness.PVC Name: PVC, mainly used for sealing, inserted conditions. It is adapted to extrusion molding, and PVC material is the material does not burn plastic parts, processing temperature stability, especially the stability of the color is not good.
