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 a filler due to its following properties:
Platy in nature
Excellent blending characteristics with oleoresinous materials.
Excellent thermal resistance
Superior electrical resistance
Chemically inert
Smooth greasy feel

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.

Talc imparts the the following properties to plastic:
Improves Chemical & Heat Resistance.
Improves impact absorbing strength.
Gives dimensional stability.
Improves stiffness, hardness, tensile strength.
Gives electrical insulation property.

The Plastic Industry uses Talc of 20µ to 1µ particle size.
