Product Description
Talc is a naturally occurring hydrated magnesium silicate mineral. Commercial suitability depends on the current product-specific mineralogical and particle specification.
Typical use: talc is evaluated as a mineral filler and processing aid in plastics, rubber, paper, and coating formulations. Confirm particle and mineralogical requirements.
Material characteristics: Talc has a layered mineral structure. Confirm particle shape, mineralogy, and physical performance requirements for the offered material rather than relying on generic consumer talcum-powder wording.
FAQ - Technical & Supply Chain
-
Q:
What is Talc used for?
A: Talc is a naturally occurring hydrated magnesium silicate used as an industrial filler and processing aid in plastics, paints, coatings, rubber, ceramics, paper, sealants and cable compounds. It can also be used as a flatting, antiblocking or anticaking agent, but the grade and mineralogy must match the end use. -
Q:
Does CAS 14807-96-6 define one Talc grade?
A: No. CAS 14807-96-6 identifies Talc as a mineral, not one fixed particle size, brightness or mineralogical composition. Natural talc varies with the deposit and may contain associated minerals such as chlorite, dolomite, calcite, magnesite, quartz or iron-bearing phases, so the CAS number alone is insufficient for lot approval. -
Q:
Which specifications and physical properties matter for industrial Talc?
A: Review particle-size distribution, brightness or whiteness, moisture, bulk density, oil absorption, surface area, mineralogical composition, acid-soluble matter and heavy metals. Talc is normally a soft, platy white to off-white powder with Mohs hardness about 1 and density commonly in the 2.6-2.8 g/cm3 range, but commercial grades vary by application. -
Q:
How should Talc be stored and handled?
A: Store Talc in a cool, dry area in tightly closed bags or containers to prevent contamination and moisture pickup. Avoid generating airborne dust during transfer and follow the current product-specific safety information for dust control, personal protection and local regulatory requirements.
