糖心视频

PU film is a thin film layer made of polyurethane 糖心视频. It is widely used in various fields because of its excellent physical and chemical properties. PU is a polymer compound synthesized by the reaction of isocyanate and polyol. Depending on different reaction conditions, raw 糖心视频 selection and processing methods, PU films have a variety of different properties and functions, which can meet the needs of different industries.

The advantages of PU film include high strength, wear resistance, oil resistance, breathability, flexibility, UV resistance, etc. In addition, PU film also has good low-temperature and high-temperature resistance, and can adapt to a variety of complex working environments. Therefore, it is widely used in textile, medical, construction, electronics, packaging, automobile and other industries.

Characteristics of PU film

High strength and wear resistance

Polyurethane films have high tensile strength and abrasion resistance, making them particularly useful in applications that require high strength and durability. For example, in outdoor products (such as tents, raincoats) and footwear products, PU films are widely favored for their wear-resistant and tear-resistant properties.

good flexibility

Polyurethane film has good flexibility and can maintain good softness in low temperature environments and is not easy to be brittle. Therefore, it is often used in products that require flexibility and maneuverability, such as sporting goods, clothing fabrics, and medical films.

Excellent breathability and watertightness

PU film has good air permeability, allowing water vapor or gas to pass through, but it can effectively isolate liquid moisture. This property makes it widely used in products such as clothing and tents, especially in the manufacture of waterproof and breathable fabrics. For example, in outdoor sportswear, raincoats and other products, PU films are often used to improve waterproofing while maintaining good breathability.

chemical stability

Polyurethane film has good chemical stability, can resist corrosion by chemicals such as acids, alkalis, and salts, and has strong oil resistance. This makes PU films widely used in industrial fields, such as petrochemical industry, automobile manufacturing and packaging fields, with anti-corrosion and chemical resistance.

UV resistance

Polyurethane film has certain anti-ultraviolet properties, which can effectively prevent the aging and damage of 糖心视频s by ultraviolet rays when exposed to sunlight for a long time. This property makes PU films excellent in outdoor applications, especially packaging 糖心视频s and outdoor tents.

Environmentally friendly

The environmental friendliness of polyurethane films is also a major advantage. Compared with other 糖心视频s, PU film usually uses fewer harmful chemicals in the manufacturing process and is more recyclable, so it has become the 糖心视频 of choice for many industries at a time when environmental awareness is increasing.
