صيغةلاصق تذوب ساخن is not static, and some raw materials can be used to improve the quality of لاصق تذوب ساخن products.

1. زيوت التشحيم

Appropriate addition of lubricants in لاصق تذوب ساخنs can improve the release performance of the plastic during heating and molding, and improve the surface finish of the product. But this kind of lubricant should not be added too much, so as not to affect the viscosity of the product. Commonly used lubricants include stearic acid, salt, paraffin wax, synthetic wax and so on.

2. عامل تلوين

Colorants are used to change the color of لاصق تذوب ساخنs. The main purpose is to beautify and decorate. About 80% of plastic products are colored to produce the final product.

3. التعبئة والتغليف

Adding fillers to the لاصق تذوب ساخن can reduce the shrinkage of the لاصق تذوب ساخن, increase the viscosity, increase the gap-filling property, and reduce the cost at the same time. Adding too much filler will affect the fluidity of the لاصق تذوب ساخن and reduce its adhesion. Common fillers are calcium carbonate, barium sulfate and clay.

4. مثبطات اللهب

The main component of لاصق تذوب ساخن is polyurethane resin, which is combustible. We can improve the flame retardancy of لاصق تذوب ساخن by adding flame retardant in the middle. Most plastics containing flame retardants are self-extinguishing or burn very slowly. Commonly used flame retardants are antimony dioxide, aluminum boron compounds, tetrachlorophthalic anhydride and so on.
