Формуласыыстық балқымалы желім is not static, and some raw materials can be used to improve the quality of ыстық балқымалы желім products.

1. Майлау

Appropriate addition of lubricants in ыстық балқымалы желімs 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. Бояғыш құрал

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

3. Қаптама

Adding fillers to the ыстық балқымалы желім can reduce the shrinkage of the ыстық балқымалы желім, 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 ыстық балқымалы желім and reduce its adhesion. Common fillers are calcium carbonate, barium sulfate and clay.

4. Фламеретардант

The main component of ыстық балқымалы желім is polyurethane resin, which is combustible. We can improve the flame retardancy of ыстық балқымалы желім 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.
