Industry Information

Polyether TPU waterproof membrane is a thermoplastic polyurethane elastomer film. Because the molecular chain contains an ether bond structure, it has excellent hydrolysis resistance and good low-temperature flexibility. It is one of the core materials for waterproof and moisture-permeable jacket fabrics. The application in jackets is mainly reflected in composite structures. A common practice is to gather...

Optimizing the coating process of hot melt adhesive film requires systematic improvements from multiple dimensions such as equipment parameters, material properties and environmental control. First of all, a precise temperature management system should be established. The temperatures of the melt glue box, glue pipeline and coating head need to be controlled independently in sections to ensure that the hot melt glue maintains its optimal melting state and avoids thermal degradation. Coating room...

The improvement of transparency of TPU films mainly relies on material formula optimization and molding process control. First of all, high-purity polyester or polyether polyurethane particles are used in the selection of raw materials, and the residual amount of isocyanate is strictly controlled to reduce light scattering caused by impurities in the raw materials. In the extrusion process, by precisely controlling the extrusion temperature...

Temperature-resistant TPU film, also known as thermoplastic polyurethane film, is a material with good temperature resistance. This material is widely used in various industrial fields due to its excellent physical properties and chemical stability. The temperature resistance of TPU film depends on its specific formula and production process. The highest temperature that TPU films of different qualities can withstand...

The waterproofing principle of waterproof and breathable film TPU (thermoplastic polyurethane) is mainly based on its unique microstructure and physical properties. TPU is a polymer material composed of soft segments and hard segments alternately arranged. The soft segments provide elasticity and flexibility, while the hard segments give the material strength and shape-retention capabilities. In TPU film,...

TPU film shows excellent application value in the field of outdoor tent waterproofing. The material has both rubber elasticity and plastic strength. It is combined with nylon or polyester base fabric through a hot-melt composite process to form a multi-layer structure with waterproof and breathable functions. A typical solution uses a TPU film with a thickness of 15 to 30 microns as the middle layer, which has been highly...

Shoe material TPU shows multi-dimensional technical value in the lightweight design of high-end running shoes. First of all, the TPU foam midsole material achieves a significant reduction in density through a microporous foaming process. It reduces weight by more than 30% compared to traditional EVA materials, while maintaining excellent energy feedback performance, allowing the running shoes to achieve a balance between cushioning and lightweight. ...

TPU hot melt adhesive membrane plays an important role in the production of seamless underwear. It is a mesh adhesive film made of thermoplastic polyurethane. It has excellent elasticity, softness and bonding properties. It can achieve strong bonding between fabrics under heating and pressure conditions, thus replacing traditional sewing processes and achieving truly seamless...

Medical TPU waterproof and breathable membrane is a material used in medical products, which can provide waterproof and breathable functions. When using this material, you need to pay attention to the following things: Cleanliness: Since it is a medical material, it is very important to ensure that it is thoroughly cleaned and disinfected before use to avoid any possible infection...

TPU waterproof breathable membrane is a high-performance material that improves the breathability of products through its unique microporous structure. This material has extremely small pore sizes that effectively block the penetration of moisture and liquid contaminants while allowing water vapor molecules to pass through. This selective breathability means that even when wet or...
