The barium sulfate masterbatch uses low-density polyethylene as the basic material, ultra-fine barium sulfate as the filler, and is made into a high-concentration yttrium product through adequate dispersion processing. It is suitable for LDPE blown film processing. Barium sulphate is used as a pad of TiO2 and pigments in plastics to reduce the amount of pigment added and to save about 10% of the cost. Applying barium sulfate (about 25%) to PP makes PP surface like ABS.
It does not affect the existing properties of PP, provides high gloss and high hardness surface, improves product acid and alkali resistance, and increases weight and feel. Barium sulphate can reach 80% of its weight. The use of natural high-quality barium sulphate is a kind of material with environmental protection due to its strong chemical inertness, good stability, good acid and alkali resistance, moderate hardness, high specific gravity, high whiteness, and ability to absorb harmful rays.
Suitable for PE, PP, ABS, EVA and PS and other related products. Improve the acidity and alkalinity of products, such as brakes to make films, shoes, increase the weight and feel, such as plastic coins, speakers, drains, home appliances shell, stereo Shell, can effectively block noise, noise.
Barium sulphate masterbatch is a high concentration, high brightness, ultrafine barium sulphate activated by surface treatment with a poly-thin polymer (PE or PP) as carrier, which is processed by strict quality control. Provide high gloss and high hardness surface, improve the acid and alkali resistance of the product,
Increase weight and feel. Barium sulphate can reach 80% of its weight. Good dispersion, strong performance stability, non-toxic and odorless, green environmental protection, printing and decorative.
5、using the ratio and method
Appropriate product requirements. The use of barium sulfate masterbatch (approx. 25% or so) on PP can make PP surface similar to ABS without affecting the existing properties of PP, providing high gloss and high hardness surface, and improving the acid and alkali resistance of the product. Increase product weight (specific gravity) and feel, barium sulfate can reach 80% of its product weight filling rate.
