In the production of plastics, talc is used as a reinforcing filler in the production of a wide range of polymeric materials (polypropylene, polyamide, polyethylene, polyvinyl chloride, polyethylene foam, foam plastic, polystyrene, fiber optic materials, etc.)
Advantages of using talc in plastics production:
Increases rigidity, compressive and tensile strength due to the lamellar shape of the particles
Increases heat resistance and UV stability
Chemical inertness improves protective properties and ensures excellent interaction with other active ingredients
Improves dielectric properties
Improves the appearance of products
Low abrasiveness reduces equipment wear
In finely dispersed form it contributes to increased impact resistance
Increases creep resistance at elevated temperatures and flexural modulus
Improves fluidity, formability, reduces shrinkage during molding, improves the surface quality of molded parts
It has high corrosion resistance
In the rubber industry, talc is used as follows:
As a reinforcing, inactive, inert filler in the production of ebonite rubbers and rubber technical products for wide consumption
For dusting freshly made rubbers, mixtures and blanks
As a filler in tire production
As a medium for vulcanization of rubber products
Advantages for rubber goods:
Used as a strengthening agent
Increases rigidity, compressive and tensile strength due to the lamellar shape of the particles
Increases heat resistance
Improves electrical insulation properties
Improves dielectric properties
Prevents materials from sticking and clumping
