Metal office chair processing is different from solid wood dining chairs. The metal office chair processing cannot do without welding, grinding, polishing, painting, and other processes. Today, let's talk about the material of the metal office chair.
The chair surface adopts the hollow blow molding manufacturing process, and the high-density polyethylene material is selected for one-time processing and molding. It has the characteristics of rounded edges and corners on the seat surface, relatively concentrated molecular weight, high bonding strength at the junction, excellent aging resistance, and excellent impact resistance. Polyethylene is a milky white translucent waxy solid with a molecular weight of 100,000 to 300,000. The density of homopolymer is generally 0.955～0.965, linear structure, few branches, and crystallinity of 80%～90%. HDPE has the smallest degree of branching, and the molecules can be packed tightly, so the density is the largest (0.941g/cm3～0.965g/cm3) and the crystallinity is high. It has high rigidity and toughness, good mechanical properties, and a high operating temperature. Anti-aging, impact resistance, high and low-temperature resistance, flame-retardant resistance, good oil resistance. Polyethylene has little water absorption, is non-toxic, and has excellent chemical stability.
The material of the ergonomic computer chair is different from that of the metal office chair, but it will also be considered from the perspective of the user. www.on-sun.com
