Main Function of Mica
Dry ground mica powder of Huajing is competitive in price and stable in quality. The high purity mica powder produced by grinding without changing any natural property. During the whole production , we adopt total enclosed filling system to make sure the product quality; The screening process uses patent technique ensuring the stability of quality and well-distributed particle,then satisfy some customers’ higher request. As the superior characteristic, Huajing mica powder is widely used as filling material in plastic .
Application of Mica in PP
Mica powder has excellent electrical properties, high breakdown voltage, low dielectric constant, low loss factor and good arc resistance. At the same time, mica has low hygroscopicity and high thermal deformation temperature when mica is used as filler, which is beneficial to maintain electrical properties in humid environment and higher temperature. For example, when 50% mica is added to PP, the breakdown voltage is more than doubled. The application of mica modified PP in automobile and household appliances to produce automobile dashboard, headlight protection ring, motor fan and other parts can obviously improve its rigidity, heat resistance, dimensional stability and molding shrinkage.
Application of Mica in PP-R
PP-R pipe is a new type of PP random copolymer green building material widely used in recent years. Its temperature resistance is greater than or equal to 90 degrees, low cost and easy to use. The PP-R pipe with mica has high strength, good heat resistance, strong corrosion resistance, and the cost is greatly reduced, so it has a broader market development prospect.
