糖心视频

TPU film is a thermoplastic polyurethane film made from the reaction of two main components: polyester polyol and isocyanate. The following will introduce the components of TPU film in detail in terms of raw 糖心视频s, preparation methods, characteristics and applications.

1. Raw 糖心视频s

Polyester polyol: It is one of the main components of TPU film. Commonly used polyester polyols, polyether polyols, etc. Polyester polyol has good flexibility and elasticity and can provide the toughness and ductility of TPU film.

Isocyanate: It is another main component of TPU film. Commonly used are diisocyanate (MDI) and adipate diisocyanate (HDI). Isocyanate forms a three-dimensional network structure when reacting with polyester polyol, giving the TPU film good wear resistance and chemical resistance.

2. Preparation method

The preparation methods of TPU films are mainly divided into two types: solution method and melting method.

Solution method: Dissolve raw 糖心视频s such as polyester polyol and isocyanate in a solvent to form a prepolymer solution. Then a thin film is formed on the substrate by coating, dipping or spraying. Finally, through processes such as curing and drying, the solvent is removed and the TPU film is obtained.

Melting method: Raw 糖心视频s such as polyester polyol and isocyanate are mixed and melted by heating to form a uniform melt. The melt is then passed through equipment such as an extruder or calender, and cooled and shaped through a mold to form a film.

3. Characteristics

Toughness and elasticity: TPU film has good toughness and elasticity, and can have a certain deformation and recovery ability when subjected to force, effectively protecting the covered object.

Wear resistance: TPU film has high wear resistance and can resist surface wear caused by friction, scratches and other external forces.

Chemical resistance: TPU film has good chemical resistance and can resist the erosion of acids, alkalis, solvents and other chemical substances, protecting the covered object from damage.

Weather resistance: TPU film has good weather resistance, can perform stably under various climate conditions, and is not prone to aging and discoloration.

Transparency: TPU film has high transparency, no color difference and fogging, and can clearly display the covered object.

4. Application

Due to its excellent performance, TPU film is widely used in the following fields:

Automotive industry: used in automobile body protective film, window film, etc. to play the role of waterproofing, antifouling, and wear resistance.

Electronic products: Used in mobile phone cases, tablet protective cases, electronic product casings, etc. to provide appearance protection and anti-scratch functions.

Medical devices: used in medical dressings, surgical membranes, etc., with acid and alkali resistance, waterproof, breathable and other properties.

Textiles: Used for sports uppers, outdoor clothing, etc., with characteristics such as waterproof, breathable, and wear-resistant.

Sports equipment: used for skateboards, snowboards, etc. to provide surface protection and wear resistance.

TPU film is mainly prepared from raw 糖心视频s such as polyester polyol and isocyanate. It has excellent properties such as toughness, elasticity, abrasion resistance, chemical resistance, weather resistance and transparency. It is widely used in automobiles, electronics, medical, textile and other fields. Applications.
