Import Calmast Mn570 Pp Filler Masterbatch — Buy in wholesale FOB from Supplier in Viet Nam

CALMAST MN570 is a polypropylene (PP) based filler masterbatch produced by A Dong Plastic Joint Stock Company in Viet Nam. The formulation combines primary PP resin, calcium carbonate (CaCO3) filler and a blend of processing‑aid additives such as dispersion agents and lubricants. It is marketed to improve heat resistance, surface quality, tear strength and tensile strength while stabilising the processing window of the final product. The supplier highlights its suitability for PP non‑woven fabric production, including shopping bags and face‑mask layers.

Calcium carbonate is a common filler in PP compounds, typically loaded between 20 and 40 per cent by weight to achieve cost reduction without compromising performance. The masterbatch is supplied as a white concentrate that disperses uniformly in the polymer melt, helping to maintain consistent colour and surface finish. Typical melt flow index values for similar PP masterbatches range from 3 to 5 g/10 min (230 °C/2.16 kg), and particle size of the CaCO3 is usually below 10 µm. Such parameters allow processors to retain familiar extrusion and injection moulding conditions while gaining the advertised mechanical gains.

The product is aimed at manufacturers of PP based consumer and industrial goods who require a balance of cost efficiency and mechanical robustness. A Dong Plastic offers customised colour and filler levels to match specific formulation needs and commits to delivering on quality, quantity and agreed delivery schedules. While the listing does not disclose a minimum order quantity, interested buyers are invited to request a formal quotation and confirm packaging, incoterms and payment terms directly with the supplier.
