Metals Explosives and disinfectant

Annealing
As an absorbent

Automotive components

Medium Fine Powder

60 Mesh

Welding electrodes, cables and wires

As protective coatings and improves dielectric properties, electrical and mechanical strength

Foundry works, pipeline, enamels, mastics, body lubricants, adhesive

Improves physical properties, anti-sag, reduce cracking

Fine Powder

100 Mesh

Texture paints
Acoustical plasters
Ceiling tiles

Improves physical properties, architectural durability. adhesion. water proofing

Superfine Powder

325 Mesh

Paints

Improves exterior durability, increase moisture resistance, flexibility, adhesion, etc.

Plastics

Improves thermal and dielectric properties, impact strength, imparts heat resistance

Rubber products including automotive tyres

Prevents adhesion of rubber compound to the cores and outer sheaths during vulcanisation

Paper

Provides stiffness, lower density and higher permeability
