According to different physical and chemical properties, plastic products can be divided into two types: thermosetting plastic products and thermoplastic plastic products. Among them, thermoplastic products have excellent characteristics and are widely used. There are many kinds of plastic products in Linyi. Today we will analyze the properties of thermoplastic products.
Thermoplastic plastic products refer to plastics that can be repeatedly softened and cooled and hardened in a specific temperature range, such as polyethylene, polytetrafluoroethylene, etc,and are classified into hydrocarbons, vinyls containing polar genes, engineering, and fibers. Various types, such as a genus, form a cured product having infusibility and insolubleness after hot working, and the resin molecules are crosslinked into a network structure by a linear structure.
Thermoplastic products have excellent electrical insulation, especially polytetrafluoroethylene (PTFE), polystyrene (PS), polyethylene (PE), polypropylene (PP) have very low dielectric constant and dielectric loss. Suitable for high frequency and high voltage insulation materials. Thermoplastics are easy to shape, but have low heat resistance and are prone to creep. The degree of creep varies with load, ambient temperature, solvent, and humidity.
