PP: common name polypropylene, used for five-star feet, handrails, foot pads and connectors with low strength requirements. Disadvantages: poor wear resistance and low surface hardness.
PVC: commonly known as polyvinyl chloride, mainly used for edge sealing and insertion conditions. It is suitable for extrusion molding. At the same time, PVC material belongs to non-combustible materials in plastic parts, and its processing and molding temperature stability is poor, especially its color stability is not good.
PU: commonly known as polyurethane. Mainly used for handrail (foam) fittings.
POM: The common name is Sai Gang. Mainly used for wear-resistant parts such as foot pads, casters, door hinges, hinges and so on. Wear resistance and pressure resistance, but poor dimensional stability.
PA: commonly known as nylon. Mainly used as foot pads, five-star claws, casters and other places with wear resistance and high life requirements. Features: Wear resistance, pressure resistance, high strength and long indoor service life. Some models, such as PA66, are resistant to high temperature of 2200, but the disadvantages are variability, easy breakage and poor sun and weather resistance.
PMMA: plexiglass (commonly known as sub-afterburner). There are five transparent materials in plastics, and PMMA is the most transparent one. The workpiece smells of acetic acid when it is cut, and it is easy to deform when it is processed. Soaking in boiling water can shape and bend. Disadvantages: the surface is easy to scratch, the hardness is low, the bending is easy to crack, and the price is more than 20% higher than ABS.
PC: commonly known as polycarbonate. This variety is also a transparent material with high surface hardness, scratch resistance, strong impact resistance, high strength and good weather resistance (that is, not afraid of sunlight). Screen partitions and sun panels in furniture are made of this material by hollow extrusion. Features: high cost, about 40% higher than PMMA.
