EC12B Additive Masterbatch
For blow film & blowmolding
EC12B compound LLDPE carrier resin, use excellent natural white color sub-micron grade CaCO3 powder, produced by special processing techniques. Use EC12B in LDPE, LLDPE, HDPE blow film or HDPE blowmolding or PP injection molding, it can improve machine's extrusion efficiency and increase film & mold's physical properties.
EC12B also has perfect dispersivity.

Usage:
EC12B can be used to make PE heavy bag, PE liquid packaging film, sanitary products bag, agricultural film, PE handbag, inside bag, high quality vest PE bag, PE garbage bag. The PE film which add EC12B can compound BOPP、BOPA and BOPET, it has no influence on compound strength and heat-sealing strength.
Use EC12B to blowmolding, it can increase containers' ESCR property, get better dimension stability.
Use EC12B in injection molding, it can improve low temperature impact resistance strength, get better dimension stability.
Recommended Addition Ratio:
The addition rate of EC12B within 5%～35%.
1) In multi-layer extrusion film, add 15%～20% in core layer;
2) Under gloss demand, add it within 5% in surface layer and inside layer.
Optimal addition rate will be confirmed by trials.
