Introduction to the types of hot melt adhesive films
There are many types and classification methods of hot melt adhesive films, the most important of which is classification according to ingredients. It can be divided into TPU hot melt adhesive film, PES hot melt adhesive film, PA hot melt adhesive film, PO hot melt adhesive film, EVA hot melt adhesive film and EAA hot melt adhesive film, etc. The properties and characteristics of hot melt adhesive films with different components and application fields are different, let’s give you a brief introduction below. Hot melt adhesive film-TPU
TPU hot melt adhesive film is also called TPU hot melt double-sided tape, and its main component is polyurethane. TPU hot melt adhesive film has good elasticity and excellent water washing resistance. It is the most popular variety among hot melt adhesive films. There are three types of TPU hot melt adhesive film: high temperature and high elasticity, medium temperature elasticity and low temperature non-elastic. Among them, the high temperature and high elasticity type TPU hot melt adhesive film is transparent in color and has excellent elasticity. It is mainly used in various types of seamless underwear; the color of the medium temperature type is Transparent and elastic; the low-temperature type is white matte in color and has no elasticity. TPU hot melt adhesive film can be used in various types of clothing, shoes and hats, daily necessities, industrial products, etc. It has good stickiness to various textiles, leather, films, sponges, rubber and other materials. Hot Melt Adhesive Film-PES
The main component of PES hot melt adhesive film is polyester, which has good water resistance. The color is white matte and has no elasticity. The melting point is about 110℃- Around 120℃, it is a medium temperature hot melt adhesive film. PES hot melt adhesive film can be widely used in the bonding of various types of clothing, daily necessities, environmental water treatment and other fields. It has good stickiness to polyester fabrics, PET films, rubber, sponges, metals and other materials, ranking second in sales. On TPU hot melt adhesive film. Hot melt adhesive film-PA
The main component of PA hot melt adhesive film is polyamide, which has good viscosity and stability, is transparent in color, inelastic, has a high melting point, and has good Dry cleaning resistance. PA hot melt adhesive film has a limited application range and is expensive. It is mainly used for bonding materials in various electronic products, PI films and other fields. Hot melt adhesive film-PO
The main component of PO hot melt adhesive film is polyolefin. It has good washing resistance, transparent color and non-elasticity. It is mainly used in the clothing industry, especially for clothing trademarks and LOGOs. The connection is widely used and the cost is low. The density of PO hot melt adhesive film is very low, only about 0.83, that is, the weight per 0.01mm thickness is 8.3 grams, which is much lighter than the TPU hot melt adhesive film which weighs 12 grams per 0.01mm thickness. This is why One of the important reasons why PO is cheap. Many people confuse PO and EAA materials. In fact, they are fundamentally different in composition and use in different fields. Hot melt adhesive film-EVA
The main component of EVA hot melt adhesive film is vinyl acetate polymer, which is an elastomer material with a low melting point, but poor water resistance, so it is not suitable for washing. It can be used in required fields and can be used for bonding in wall coverings, home textiles, building materials and other fields. It has good stickiness to polypropylene (PP), wood paper, EVA foam, various sponges and other materials.
