Calcium carbonate filling masterbatch is made through special processing techniques and added new types of plastic additives & coloring agents, and applied foreign up-to-the-minute formula and domestic extremely advanced twin screw extruder. This product is treasured and welcomed unparalleled by lots of customers for its excellent property, it is a new type of domestic substitute presently, this make a new prospect for the development and application of plastic products.
ONE: PRODUCT FEATURE
1.improve plastic thermal conductivity, short molding time, increase output, lower cost,improve printing quality.
2. lower the shrinkage and warp of plastic products, improve anti warp coefficient and heat resisting temperature.
3.improve anti impact property and lower conglutination of plastic products..
4.used with PP, PE plastic, could made its products easy to print and coat.
5.partly substitute white pigment to lower cost.
6.well intermiscibility with polyolefin resin, easy to disperse, large filling load(10-80%)
7.color masterbatch used in plastic products , the coloring power is strong.
8. low dust used in circular weaving machine, opposite drawing silk, strand strength is strong, no affection to weaving property and producing technique.
