Customized plastic profiles are industrial and daily products made primarily from various plastics like PVC、ABS etc.,, with the addition of functional additives such as stabilizers and anti-aging agents, and then formed through high-temperature extrusion. According to performance, they are divided into rigid and soft types: rigid profiles are mostly used for structural components like building doors and windows and pipes, while soft profiles are used in flexible scenarios such as cable sheathing and hoses. They have characteristics such as corrosion resistance, high strength, and low cost, and can replace some metal materials. Special products can also be customized by combining soft and rigid materials.
