The Material Of Hot Melt Adhesive

The Material Of Hot Melt Adhesive

Hot Melt adhesives are thermoplastic materials composed of additives, pigments, stabilizers and polymers. Hot melt adhesive mainly includes high molecular weight polymer, adhesive, plasticizer these three parts, of which high molecular weight polymer is the main adhesive, adhesive is to provide more adhesion and wetting properties, plasticizer is the ability to control viscosity. In addition, hot melt adhesive has the characteristics of high strength, oxidation resistance and strong adhesive force, which is often suitable for multi-functional packaging applications.

First, the characteristics of hot melt adhesive are as follows:
1. Hot melt adhesive has the characteristics of high strength, aging resistance and non-toxic. Commonly used in fabric, metal, wood, plastic, lampshade, leather, crafts, paper products, ceramics, pearl cotton and other packaging applications.
2. The Hot Melt Glue rod made of hot melt glue has the characteristics of fast adhesion, good thermal stability and film toughness.

Second, the use of hot melt adhesive is as follows:
1. Hot melt adhesive is now widely used in daily chemical packaging, paper packaging, furniture daily necessities, label adhesive and other industries.
2. Water sealing tape, hot melt adhesive can be made into water sealing tape, tape composition can be single or multi-layer film composition. Waterproof tape can prevent the leakage of water, this product is mainly used in waterproof clothing, underwear, outdoor clothing, mountaineering clothing, medical dustproof clothing, anti-seepage blood mat and other waterproof clothing products.
3. Shoe material, fabric. Hot melt adhesive can be introduced into product design, reduce labor costs and reduce weight, and is now widely used in the field of footwear.

Third, the skills of hot melt adhesive purchase are as follows:
1. Choose the color, the general hot melt adhesive has two colors: yellow and white. In general, yellow hot melt adhesive is better than white adhesive.
2. Temperature resistance, generally speaking, the temperature resistance of hot melt adhesive is not very good, such as the temperature is too high, there will be softening, the temperature is too low, hot melt adhesive will become brittle. Therefore, the choice of hot melt adhesive should take into account the temperature change of the environment.
3. Viscosity, the viscosity of hot melt adhesive is divided into two kinds, that is, early viscosity and late viscosity. Only the early viscosity and late viscosity are consistent, is a good hot melt adhesive, so that the object to be connected to maintain stability.

Summary of the article: The above is the hot melt glue what material and hot melt glue purchase skills of all content, I hope to help you.
