Plastic tube sleeves are caps made from plastic, which is a class of plastic, a type of synthetic polymer material with plasticity. It, along with synthetic rubber and synthetic fibers, forms the three indispensable synthetic materials in today's daily life. Specifically, plastics are primarily 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 compared to other materials include the following aspects.

1. Lightweight plastic is a material with lower weight, with a relative density ranging between 0.90-2.2.

2. Thermal poor conductors offer noise reduction and vibration damping. Generally speaking, plastics have a low thermal conductivity, ranging from 1/75 to 1/225 of steel. The micropores in foam plastics contain gas, which makes them excellent for insulation, noise reduction, and vibration resistance.

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