Additive Masterbatch EC21C
EC21C Masterbatch with LLDPE carrier resin, use excellent white color micron Caco3 powder, produced by special processing techniques. Adding this masterbatch in LDPE, LLDPE, HDPE. It can improve film ′extrusion efficiency and increase film or bottle ′physical properties. EC21C Masterbatch also has perfect dispersivity.
Advantage
1. EC21C Masterbatch has the highest mechanical intensity preservation rate.
2. When they are used in resins,it shows stability performance.
3. Can be produced according to customer requirements.
4. EC21C Masterbatch fulfill RHOS certification and FDA standard in USA. No heavy metal, no poison, safety for good packing.

Applications Areas
EC21C Masterbatch can be used to PE heavy bags, PE liquid packing film, sanitary products bags, agricultural film, PE handbags, inside bags, high quality vest PE bags, PE garbage bags. The film which add EC21C Masterbatch can be compound with BOPP, BOPA and BOPET have no influence on compound strength and heat-sealing strengh.
EC21C is suitable for molding and Injection plasstic products. It can improve heat conduction and increase products′size stability.
Recommend Addition Ratio
The addition rate ofEC21C Masterbatch is about 5%~30%.
1) In multi-layer extrusion film:we suggest to add 15%~20% in core layer.
2) Under gloss demend, we suggest to add 5% in surface layer and inside layer. Optimal addition rate will be confirmed by trials.
