Barium sulfate masterbatch (alias: barite)

It is a high-concentration, high-whiteness ultra-fine barium sulfate processed by surface treatment activation with polyolefin polymers (PE or PP) as carriers.

Main function: Improve the acid and alkali resistance of products, and can be used in products such as sneakers; can enhance weight and touch, and can be used in plastic audio housings. It has unparalleled thermal stability and excellent dispersibility, which significantly reduces production costs.

Barium sulfate is used as a spacer for titanium dioxide and pigments in plastics to reduce the amount of pigment added and save about 10% of the cost. Applying barium sulfate (about 25%) to PP can make the surface of PP similar to ABS without affecting the existing characteristics of PP, providing a high gloss and high hardness surface.

Barium sulfate can reach a filling rate of 80% of its weight. It can be used in drainage pipes, speakers, and audio to effectively isolate noise and noise. It can be used in curtains to increase weight. It can be used in the shell of household appliances to provide high gloss, good color, scratch resistance, good dimensional stability, etc.
