Both EVA hot-melt adhesive film and TPU hot-melt adhesive film are one of the types of hot-melt adhesive film, which are environmentally friendly adhesives. Their ingredients are different, so they do not belong to the same type of hot melt adhesive film, so what is the difference between them in terms of performance and use? Let's take a look together.
Washable TPU hot melt adhesive film
The main component of TPU hot melt adhesive film is polyurethane. This material has different properties and characteristics according to high melting point and low melting point. Among them, the color of TPU hot melt adhesive film with medium temperature and high temperature melting point is transparent and elastic. The higher the melting point of the TPU, the better its elasticity and transparency; while the color of the low-temperature TPU hot melt adhesive film is white and translucent, and has no elasticity.
TPU hot melt adhesive film has good washing resistance, and has good adhesion to various textile fabrics, leather, TPU film, polyurethane foam, some rubber and other materials. It is mainly used in the fields of clothing, shoes and hats, and not suitable for daily necessities and other fields. many.
Medium temperature TPU hot melt adhesive film models: HJU120, XJU120. Low temperature TPU hot melt adhesive film models: XJU83, HJU80, PE-DJU90. High temperature TPU hot melt adhesive film model: GXJU150.
Low cost EVA hot melt adhesive film
The main component of EVA hot melt adhesive film is vinyl acetate, which is also one of the elastomer materials. It has good adhesion to various sponges, PP (polypropylene), EVA foam, wood paper, various rubber and other materials. The melting point of EVA hot-melt adhesive film is relatively low, and most of the melting point range is between 60-80°C, which belongs to low-temperature hot-melt adhesive film. The disadvantage is that the product has poor washing resistance, and is rarely used in clothing and other fields. It is mainly suitable for daily necessities and industrial products. The advantage is that the product cost is low.
EVA hot melt adhesive film model: HJV85, HJV90.
The difference between eva hot melt adhesive film and tpu hot melt adhesive film
Although Eva hot melt adhesive film and tpu hot melt adhesive film have a lot in common in terms of physical form, they are completely different in terms of property characteristics. Next, let's take a look at the detailed differences between eva hot melt adhesive film and tpu hot melt adhesive film:
1. The difference in product characteristics:
Eva hot melt adhesive film has poor washing resistance, and is not resistant to dry cleaning, high temperature resistance of 80 degrees, and low temperature resistance of minus 20 degrees;
Tpu hot melt adhesive film has good washing resistance, high temperature resistance at 110 degrees, and low temperature resistance at minus 20 degrees; at the same time, it also has relatively good tensile properties.
2. The difference in melting point:
There are three main melting points of Eva hot melt adhesive film, namely 80 degrees, 90 degrees and 110 degrees. Among them, the eva hot melt adhesive film with a melting point of 80 degrees is widely used.
There are many types of melting point of Tpu hot melt adhesive film, the low melting point can reach 65 degrees, the high melting point is around 180 degrees, the span is larger, and the application is more extensive!
3. Differences in applicable industries:
Eva hot melt adhesive film is mainly suitable for: eva handicrafts, floor mats, pet materials, wall covering adhesive, non-woven fabrics, photovoltaic panel materials, and diving suits and other sporting goods.
Tpu hot melt adhesive film is mainly suitable for: leather, shoe materials, microfiber, mobile phone leather case computer bags, jackets, sports fabrics, paper, ceramics, plastics and textiles and other industries.
There is no absolute who is good and who is bad
To say which is better, TPU or EVA hot melt adhesive film from www.cn-hma.com, is actually impossible to compare, because they are suitable for different material fields, which does not mean that which material is more expensive means it is better, or it depends on your plan It depends on the bonding material and usage. If you plan to use it for clothing, such as the bonding of clothing trademarks, etc., then definitely TPU hot-melt adhesive film is more suitable; and if you plan to use EVA foam for insoles, etc., then EVA hot-melt adhesive film is more suitable Some. Specifically which material should be used and which composition of the hot melt adhesive film can be consulted with the business personnel of the manufacturer, and they will recommend a suitable product model for you according to your material and process conditions. At the same time, friends who have needs can also leave me a message or private message. We are a manufacturer of hot melt adhesive films.
