Polyethylene Powder Industrial Grade Chemicals PE / HDPE / LDPE CAS 9002-88-4

Description:
Polyethylene is a thermoplastic polymer composed of ethylene monomers. It is a versatile material known for its excellent chemical resistance, low cost, and ease of processing. Polyethylene is available in various forms, including high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE), each with slightly different properties.

Specification:
Chemical formula: (C2H4)n
Molecular weight: Varies depending on the polymer grade and molecular weight distribution
Appearance: Solid, typically in the form of pellets, powders, or films
Density: Varies depending on the polyethylene type (HDPE, LDPE, LLDPE)
Melting point: Varies depending on the polyethylene type (HDPE: 120-180°C, LDPE: 105-115°C, LLDPE: 120-135°C)

Application:

1. Packaging: Polyethylene is extensively used in packaging applications due to its excellent barrier properties, moisture resistance, and durability. It is commonly used for manufacturing plastic bags, films, containers, bottles, and wraps.

2. Pipes and fittings: High-density polyethylene (HDPE) is widely used in the construction industry for pipes and fittings due to its excellent strength, chemical resistance, and flexibility. HDPE pipes are commonly used for water supply, gas distribution, and drainage systems.

3. Wire and cable insulation: Polyethylene is employed as insulation for electrical wires and cables due to its excellent electrical properties and resistance to heat and moisture. It provides electrical insulation and protection for various applications, including power transmission, telecommunications, and automotive wiring.

4. Automotive components: Polyethylene finds application in the automotive industry for manufacturing various components, including fuel tanks, bumpers, interior trim, and under-the-hood parts. It offers good impact resistance, chemical resistance, and lightweight properties.

Features:

1. Chemical resistance: Polyethylene exhibits excellent resistance to a wide range of chemicals, making it suitable for applications where contact with corrosive substances is expected.

2. Moisture resistance: Polyethylene has low water absorption, making it resistant to moisture. This property is beneficial in applications where moisture barrier properties are required, such as packaging and underground piping.

3. Ease of processing: Polyethylene can be easily processed through various methods, including extrusion, injection molding, and blow molding. It can be shaped into different forms, making it adaptable to different manufacturing processes.

4. Lightweight: Polyethylene is a lightweight material, which is advantageous in applications where weight reduction is desired, such as automotive components and packaging.

5. Recyclability: Polyethylene is recyclable, allowing for the reuse of the material and reducing environmental impact.
