Magnesium Silicate Mineral
Talc Powder
Mg₃Si₄O₁₀(OH)₂
Refined talc powder with high brightness and lamellar particle structure. Low abrasion index suitable for soft-touch applications in plastics, paint, and industrial products.
Key Benefits
Why formulators choose Talc
01
Lamellar (plate-like) particle structure reinforces polypropylene — improves stiffness and heat deflection temperature at lower loading than competitor fillers
02
Mohs hardness of 1 (softest mineral) — does not wear processing equipment screws, dies, or mixing components, unlike silica-based fillers
03
Nucleating agent in plastics — accelerates crystallisation of PP and nylon, improving dimensional stability and cycle time in injection moulding
04
Lubricity effect in coatings — contributes to anti-block and anti-scratch performance in film and paper coatings
05
pH stability (8.5–9.5) compatible with latex paint systems — does not interfere with film formation or pigment dispersion

FAQ
Common Buyer Questions
Questions we receive from procurement and technical teams before a first order. If your question isn’t listed, contact us directly.
Ask a Question →Which talc grade is best for polypropylene compounding?
LM-TL-10 (10 µm D97) is recommended for PP compounding — fine particle size maximises nucleation efficiency and mechanical reinforcement. LM-TL-20 is a cost-effective alternative where stiffness gain is the goal but the highest performance level is not required.
What does 'lamellar' particle structure mean?
Talc particles are flat and plate-like (lamellar) rather than blocky or spherical. This shape provides mechanical reinforcement in plastics, improves barrier properties in films, and gives a smooth, silky feel in coatings. These properties are not achievable with blocky fillers like calcium carbonate at equivalent loading.
Is talc suitable for paint applications?
Yes. LM-TL-10 and LM-TL-20 are used in interior and exterior paint formulations for anti-sedimentation, improved scrub resistance, and controlled gloss. Talc is particularly effective in primer, undercoat, and textured coating formulations.
Can you supply cosmetic-grade talc?
Our talc is industrial grade, not cosmetic grade. Cosmetic applications require asbestos-free certification and heavy metals compliance testing that is outside our current scope. We recommend contacting a specialist cosmetic minerals supplier for those requirements.
