Highlights of TPU against EVA hot melt films
EVA hot melt adhesive film and TPU hot melt adhesive film are two very important types of hot melt adhesive products. It is very difficult to distinguish them only from physical morphology. It's hard for consumers to distinguish them in terms of appearance.
EVA hot melt film and TPU hot melt film have a lot in common in physical morphology, but they are totally different in attribute characteristics. Next, let's look at the detailed differences between EVA hot melt adhesive film and TPU hot melt adhesive film:
1. Differences in product characteristics:
EVA hot melt adhesive film has poor water wash resistance, dry cleaning resistance, high temperature resistance and low temperature resistance of - 20 ℃; TPU hot-melt adhesive film has good washability, high temperature resistance at 110 ℃, low temperature resistance at - 30 ℃; at the same time, it also has good tensile properties.
2. Differences in melting point:
There are three kinds of melting point of EVA hot melt adhesive film, which are 80 ℃, 90 ℃ and 110 ℃. Among them, EVA hot melt film with 80 degree melting point is widely used. TPU hot melt adhesive film has many types of melting point, the low melting point can achieve 65 ℃, the high melting point is about 180 ℃, the range is large, and the application is more extensive!
3. Differences in applicable industries:
EVA hot melt adhesive film is mainly applicable to EVA crafts, floor mats, PET materials, wall cloth back glue, non-woven fabrics, photovoltaic panel materials, diving suits and other sporting goods.
TPU hot melt adhesive film is mainly used in leather, shoe material, super fiber, mobile phone leather cover computer bag, clothing, sports fabric, paper, furniture, ceramics, plastic, textile and other industries. It is used in the fields of clothing bags, reflective materials, automobile interior decoration, sports shoes mesh composite fabric, seamless underwear, seamless pocket, seamless mobile phone cover, waterproof eisure zipper, logo trademark, water filled (oil, air)bag, leather fabric composite, foam composite, etc.
