What is desiccant masterbatch?

The dehumidifier masterbatch is known in the market as anti-gas masterbatch, anti-bubble masterbatch, bubble-proof masterbatch. The use of masterbatch dehumidifier is to remove the skin, bubbles and grains on the surface of the product, to remove gases and moisture from the raw materials.
Many of the intermediate products of the polymer industry, including masterbatch calcium carbonate, recycled materials, absorb part of the moisture in the environment, which is released during the production of the final product due to the high process temperature, and forms bubbles in plastic films and holes in extrusion parts. The injection appears Using small amounts of moisture-absorbing masterbatch around 0.4-0.5% (in other words, 400 to 500 grams per 100 kg) due to the highly porous surfaces of this additive masterbatch reacts with the water in the intermediate materials and practically removes it from the chain, while reducing The cost of polymer production and regeneration increases and improves the appearance of the product.
