How do waterproof and breathable films keep you dry and comfortable
How does waterproof performance keep you dryWaterproof films can prevent liquids from penetrating and form a barrier on the fabric surface. For instance, the waterproof film of outdoor clothing can prevent rainwater from seeping in, keeping the wearer dry.Its surface energy is low, making it difficult for water droplets to adhere and causing them to roll off, thus preventing water accumulation and seepage.How does breathability keep you comfortableThe waterproof breathable film allows water vapor to escape through the micro-porous structure or breathable layer, preventing sweat accumulation and keeping the skin dry.It can also regulate the internal humidity, reduce it, and prevent stuffiness and discomfort.The synergistic effect of the two performancesThe waterproof and breathable film has both waterproof and breathable properties. It can not only prevent external moisture from entering but also expel internal moisture, allowing people to stay dry and comfortable in various environments. Moreover, its performance will be continuously optimized to meet the needs of different scenarios, such as outdoor sports and medical care. -
Advantages of TPU film
High tensile strength and wear resistance: TPU films feature high tensile strength and excellent wear resistance, capable of withstanding significant tensile forces and daily friction, thereby extending the service life of products. They are suitable for applications in outdoor equipment and automotive interiors, among other fields. Good flexibility and elasticity: With excellent flexibility and elasticity, it can deform along with the movement of items without affecting its use, such as sports protective gear and electronic product protective cases, meeting the needs of different scenarios. Outstanding waterproof and breathable performance: Effectively blocks water penetration while allowing water vapor to pass through, keeping the interior dry. It is widely used in outdoor clothing, medical supplies, etc., to cope with bad weather and the excretion of human sweat. Strong chemical resistance: It can resist the erosion of various chemical substances and is suitable for medical, automotive and other fields. It is not easily damaged when in contact with disinfectants, chemicals or oils. Good temperature resistance and flame retardancy: resistant to high and low temperatures, with stable performance in different environments; It has a flame-retardant effect when exposed to fire, slows down the burning speed, is suitable for various scenarios, and improves safety performance. Excellent plasticity and composite performance: It can be formed as needed, is easy to be compounded and processed, and meets the diverse product and functional requirements, such as food packaging, electronic product protection, etc. Environmental protection and health: Recyclable, low toxicity, meeting environmental protection and health requirements, suitable for medical, food and other fields. Outstanding appearance performance: Good transparency and gloss, which can enhance the appearance grade of the product, suitable for various products such as electronic products and automotive interiors. -
Regarding TPU film
Thermoplastic polyurethane films are also commonly referred to as TPU, polyurethane or PU films. Thermoplastic polyurethane was first developed in 1937 and has been used for decades to manufacture a type of unique films. There are several characteristics that make TPU films superior to common films such as PP,PE and PVC. The molecular structure of TPU film is simple. When TPU is burned or incinerated, it does not pollute the air. After being buried in the soil, it will naturally degrade within 3 to 5 years under the action of humidity and microorganisms. It is a good alternative to PVC products and a mainstream product in environmentally friendly production. There are mainly three chemical categories of TPU films. These include polyester, polyether and polycaprolactone. In addition, polyurethane TPU films are available in aromatic or aliphatic varieties. Aromatic films are used in most consumer applications, while aliphatic films are used in special applications that require high optical transparency or specific adhesive properties. Polyester TPU film is compatible with polar plastics such as PVC, making it an ideal choice for various laminates.
