What kind of material does the billboard characters have high hardness?

PPE material is the abbreviation of polystyrene.

The following is a detailed explanation:

1. Brief description of polystyrene: Polystyrene is a thermoplastic, which is a polymer of styrene. Due to its excellent processing performance and physical properties, it is widely used in various products. Its chemical structure is stable, has good corrosion resistance, and has good resistance to many chemicals.

2. The main characteristics of PPE materials:

Good mechanical properties: Polystyrene has high strength and hardness and can withstand a certain amount of pre ssure and impact.

Chemical stability: It is resistant to the effects of most acids, alkalis and salts, so it is often used to make chemical equipment and containers.

Excellent electrical properties: It has excellent insulation properties and low dielectric constant, and is suitable for applications in the electronic and electrical fields.

Easy to process: Products of various shapes can be made through injection molding, extrusion, blow molding and other processing techniques.

3. Application fields of PPE materials: Due to its excellent performance, polystyrene products are widely used in packaging, construction, furniture, electrical appliances, automobiles and other fields. For example, transparent polystyrene films are often used as packaging materials, and sheets made of them are often used to make display stands and billboards. In addition, polystyrene is often used as an insulating material in the electronics and electrical fields.

In general, PPE material, polystyrene, is a thermoplastic with excellent properties and is widely used in many fields.
