Sodium Sulphate Masterbatch

A mineral-based filler masterbatch containing sodium sulphate, used as a cost-effective additive in polyethylene and other compatible polymer systems. It can improve process economics and may provide controlled stiffness, density and processing characteristics depending on the formulation and dosage.

Sodium Sulphate Masterbatch is a mineral-based filler masterbatch formulated with sodium sulphate (Na₂SO₄) dispersed in a suitable polymer carrier. It is designed for incorporation into polyethylene and other compatible thermoplastic systems to optimize material cost and modify selected physical and processing characteristics.
It can be used as a cost-effective filler in applications where the required balance of cost, stiffness, density, opacity and processability can be achieved through controlled addition.
