Activated Calcium Carbonate [CALSEEDS]

CALSEEDS

CALSEEDS is mainly used in rubber to improve modulus, tensile strength and hardness.
It can be used in high-ratio formula due to its excellent dispersibility.

CALSEEDS P

CALSEEDS P is mainly used in plastics.
The product is especially suitable for PVC to improve whetherability, heat resistance, and surface smoothness.

CALSEEDS PL, PL-10 and AS

CALSEEDS PL, PL-10 and AS are used for PVC and Acryliric sol, sealants and paints.
These products give unique viscosity and thixotropy and improve various properties such as discharge, anti-slip and storage stability.

CALSEEDS AS

CALSEEDS AS is a special grade to improve anti-slip property.

CALSEEDS PLS505

CALSEEDS PLS505 is mainly used for sealants and adhesives.
The product has excellent dispersibility, viscosity and storage stability.
