SK-T 49

Technical DataSheet | Supplied by Thiele Kaolin Company

Fine particle size, high surface area, air float kaolin clay. Acts as an excellent, cost effective, reinforcing functional filler. Gives the ability to improve the physical properties, namely tensile strength, stiffness and abrasion resistance. Provides more reinforcement as compared to GCC, good whiteness and brightness. Very good at screening UV light. Effective at replacing up to 25% of the TiO2. Aids in the dispersion. Has a platy structure and good aspect ratio. Improves heat deflection (HDT) and abrasion resistance. Provides improved physical and optical properties. Recommended for use in rigid-PVC applications, thermoplastic applications and rubber applications.
