Wholesale Price Plastic Materials LDPE HDPE LLDPE

Polyethylene is a polymer formed from the polymerization of ethylene monomer and has the following properties:
1. Physical properties: polyethylene is a colorless, odorless, non-toxic solid with a white or transparent appearance. It has good ductility, toughness and wear resistance, but also has high strength and impact resistance.

2. Chemical properties: polyethylene has good corrosion resistance to most chemical substances and high acid and alkali resistance. However, it is sensitive to some organic solvents, oxidants and ozone.

3. Melting point and ignition point: the melting point of polyethylene is about 110°C, and the ignition point is about 340°C. Therefore, polyethylene has high thermal stability under normal conditions.

 Polyethylene has a wide range of applications, including but not limited to the following:

1. Packaging materials: The good flexibility and transparency of polyethylene make it a commonly used packaging material, such as plastic bags, bottles and packaging films.

2. Building materials: Because polyethylene has good weather resistance and corrosion resistance, it is widely used in building materials, such as water pipes, cable insulation materials and plastic film.

3. Medical devices: Due to the corrosion resistance of polyethylene to general drugs and chemicals, it is widely used in the preparation of medical devices, medical packaging and medical dressings.
