Plastic tube sleeves are caps made from plastic, primarily a type of plasticizable synthetic polymer material. It, along with synthetic rubber and synthetic fibers, forms the three indispensable synthetic materials in today's daily life. Specifically, plastics are mainly composed of synthetic resins and can be shaped under conditions of temperature and pressure. Plastic tube sleeves maintain their shape at room temperature. The main performance characteristics of plastics, when compared to other materials, include the following aspects.

Lightweight Plastic is a material that is relatively light, with a specific gravity ranging between 0.90-2.2.

2. Heat的不良conductors possess noise-reduction and vibration-damping properties. Generally speaking, the thermal conductivity of plastics is relatively low, equivalent to 1/75 to 1/225 of steel. The tiny pores of foam plastics contain gas, offering good thermal insulation, soundproofing, and vibration resistance.

3. Excellent chemical stability: The majority of plastics exhibit good resistance to corrosion from acids, alkalis, and other chemicals.
