masterbatch-EC32B

filler masterbatch CaCO3, content: 83%

EC32B Additive Masterbatch

EC32B use excellent micron CaCO3 poweder, produced by special processing techniques. Adding this masterbatch in LDPE, LLDPE, HDPE film blowing application. It can improve film 's extrusion efficiency and increase film or bottle 's physical properties. EC21C also has perfect dispersivity.

Usage

EC32B can be used to make PE heavy bags,PE liquid packaging film,sanitary products bags,agricultural film,PE handbags,inside bags,high quality vest PE bags,PE garbage bag. The film which add EC21C can be compound with BOPP, BOPA and BOPET, have no influence on compound strength and heat-sealing strength.

Recommended Addition Ratio

The addition rate of EC32B is about 5%~30%.

1) In multi-layer extrusion film: we suggest to add 15%~20% in core layer;

2) under gloss demand, we suggest to add within 5% in surface layer and inside layer.

Optimal addition rate will be confirmed by trials.

Package, Transportations and Storage

1) PE heavy-duty bag , 25kg / bag.
