How to improve the quality of hot melt adhesive products?

Now some plastics themselves are simple resins, such as polyethylene and polystyrene, etc., and they are all called single-group plastics.

 

1. Flame retardant

Additives that can improve the flame retardancy of hot melt plastics are called flame retardants. Most plastics that contain flame retardants are self-extinguishing, or burn very slowly. Commonly used flame retardants now include antimony oxide, aluminum boron compounds, and tetrachlorophthalic anhydride.

 

2. Lubricant

Lubricants are additives used to improve the release properties of plastics during heating and molding, and improve the surface finish of products. Commonly used lubricants are stearic acid, salt, paraffin and synthetic waxes.

 

3. Reinforcing materials and fillers

In many plastics, reinforcing materials and fillers account for a considerable proportion, especially reinforced plastics and calcium plastic materials.

 

4. Colorants

Colorants are used to color hot melt plastics. Mainly for beautification and decoration. About 80% of plastic products are colored to produce the final product.
