Томъёохалуун хайлмал цавуу is not static, and some raw materials can be used to improve the quality of халуун хайлмал цавуу products.

1. Тосолгооны материал

Appropriate addition of lubricants in халуун хайлмал цавууs 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. Өнгө будгийн бодис

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

3. Баглаа боодол

Adding fillers to the халуун хайлмал цавуу can reduce the shrinkage of the халуун хайлмал цавуу, 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 халуун хайлмал цавуу and reduce its adhesion. Common fillers are calcium carbonate, barium sulfate and clay.

4. Flameretardant

The main component of халуун хайлмал цавуу is polyurethane resin, which is combustible. We can improve the flame retardancy of халуун хайлмал цавуу 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.
