It was observed that the properties of the composites are strongly influenced by concentration of the particles, testing temperature, and particle size. In general, the addition of different talc grades to the rTPO increased flexural modulus and heat distortion temperature of the composites, ascribed to the reinforcement effect of the particles.
What is Talc? Talc is an hydrated magnesium silicate, belonging to the subclass of phyllosilicates. Its crystals are thin and lamellar forming, when massive, wide range of colours (i.e.: white, pink, green, grey or black). Talc can be found in various grades, different by purity, colour and lamellarity.
Two different minerals with similar physical properties are talc and pyrophyllite. Their physical properties are nearly identical. Both are very soft: talc is the softest mineral on the Moh's hardness scale at 1, and pyrophyllite is 1 to 2.
Discover the talc facts and versatile applications of talc in industries like plastics, cosmetics, coatings, and more.
Talc is the principal component of body powders, face powders and eye powders. It is a naturally occurring mineral. It is used for its physical properties: softness, heat stability and lubricity.

Injected polypropylene (PP)/talc composites were studied to evaluate the influence of different talc morphologies on their final mechanical properties. Talc genesis is responsible for type and content of associated minerals, crystalline degree, particle size distribution, and specially, morphology. Consequently, when talc is incorporated into PP, …
TALC. Talc is a hydrated magnesium silicate. It is the softest mineral on earth. All talc powders have a lamellar structure and are organophilic, water-repellent and chemically inert. There are many different grades of talc powder. Each talc mine has its own characteristics, its own geology, formed millions of years ago.
Food Industry: Food-grade talc is used as an anti-caking agent in several food products to prevent clumping, such as in spices and powdered food. Industrial Applications. …
Talc is a commonly used ingredient in cosmetics and personal care products due to its ability to absorb moisture, prevent caking and give a silky feel on the skin. However, because of increasing concerns about potential health risks associated with talc, many cosmetic brands have started using other different names for talc in their products.
