Main Usage of PVC Resin
Our pvc resin is recommended for formulating vinyl rigid compounds suitable mainly for processing by extrusion (of rigid pipes and fittings, tubes and plates, window profiles and other profiles or outdoor furniture with weatherability, siding,etc.) injection of rigid profiles and calendering of rigid sheets.
SG3 is for films, hoses, leathers, wire cables and other general purpose soft products.
SG5 is for pipes, fittings, panels, calendaring, injection, moulding, profiles, and sandals
SG7 / SG8 is for bottles, sheets, calendaring, rigid injection and moulding pipes.
3.PACKAGING-STORAGE:
It is packed in:
25kg net bags of polypropylene lined with polyethylene, (permissible limits ± 0.2kg).valve papebags, 25kg net (permissible limits ± 0.15kg), palletized and wrapped with polyethylene film.
The product should be stored in cool, dry and well vented areas far from inconsistent materials. Polyvinyl chloride presents the risk of electrostatic energy storage, that is why the storage silos are earthed.
