CA-3
Aksab CA-3 is a neutral to slightly basic Calcium stearate.
It promotes the fusion in all PVC applications independentlyon the stabilization system.
Aksab CA-3 shows synergistic effects with Aksab ZN53 and Akstab NLS28.
Definition
Calcium stearate (syn. Calcium distearate)
Application
Rigid PVC
Plasticized PVC
PE, PP and similar thermoplastic resin processing
Recommended dosage
Depends on the formulation, processing conditions and the type of products; usually in the range of 0,3 - 1,2 phr
Mixing
A minimum temperature of 120°C is recommended for optimal dispersion in the dryblend.
