Desiccant Masterbatches it was also known as defoaming masterbatch.
Plastic product including extrusion, injection and film process is made
of plastic raw material melt with high temperature by extrusion molding
equipments. The quality of plastic product is directly and closely
related to the compaction and drawback rate for molding product. The
moisture content in raw material will directly impact to the quality of
plastic product. The moisture will become steam in the process of
plastic product and lead to drawback with bubble, crackle, spot and hole
in plastic product, so that it influence the mechanics property and
appearance of plastic product.
In order to improve the
quality of plastic product and wipe off the
moisture in raw material, currently people mainly adopt heating and
drying the raw material before process. This process needs
manufacturertor buy additional drying equipments with high temperature.
Increase technology process, the production cost and labour.
Desiccant masterbatches is a new high technology functional
masterbatches specially designed to remove the water, bubble and
drawback in plastic product with PE,PP, PVC, ABS, EVA, PS and PA as raw
material. When adding desiccant masterbatches, do not need drying
process for plastic raw material, and reduce the cost of plastic
product, increase production efficient and largely improve the mechanics
property and appearance of plastic
