Talc Powder For Plastics / Polymer

img_silverstone

With the plastic industry on a fast growth-track, the usage of Talc is growing fast in PP, HDPE, LDPE, PVC, ABS & Thermosetting Compounds. Talc is having a huge demand as filler. In Polypropylene, Talc is used to improve mechanical strength and scratch resistance. The Automotive industry uses Talc for dashboards, interior trims, bumpers etc. Talc is also used in plastics for computer bodies and garden furniture where increased UV resistance is a highly desirable characteristic. It is also used as antiblocking agent in film-like bags used for fruits, vegetables etc. Many compounding factories are also using Talc.

Benefits:

Increase In Impact Strength

Addition up to 10% loading will increase the impact strength.

Rigidity At Higher Temperature

Talc is efficient in Deflection of Temperature and thus maintains the rigidity of the polymer compound at high temperature.

Weight To Volume Ratio

Due to its low bulk density, Talc does not adversely affect the volume of the Polymer compound, which usually happens when you add any filler to the polymer.
