Material characteristics and applications of polyurethane film

1. Material characteristics of polyurethane film

Polyurethane film is a polymer material made of polyester, polyether or polyimide polyurethane resin. It has the following characteristics:

1. Good flexibility: Polyurethane film can be easily folded, bent and shaped, and is not easy to break or deform.

2. High strength: Polyurethane film has excellent strength and wear resistance and can withstand large amounts of stretch and pressure.

3. Good heat resistance: Polyurethane film can maintain stable performance in the temperature range of -30°C to 150°C and is not easy to age or deform.

4. Good transparency: Polyurethane film can transmit light and has good optical properties.

5. Excellent waterproofing: Polyurethane film has good waterproofing properties and can be used as a waterproof layer.

2. Application fields of polyurethane film

1. Electronic field: Polyurethane film can be used to make insulation layers, film capacitors, capacitor separators and battery separators for electronic products.

2. Optoelectronics field: Polyurethane films can be used to make touch screens, optical films, brightness gain films, etc.

3. Medical field: Polyurethane film can be used in medical dressings, infusion bags, pharmaceutical packaging and surgical equipment.

4. Environmental protection field: Polyurethane film can be used as environmental protection bags, garbage bags and other materials.

5. Other fields: Polyurethane film can also be used in printing, packaging, tempered film, etc.

In general, polyurethane film, as a high-performance material, has broad application prospects and development space in many fields.
