Low Density Polyethylene (LDPE)
Linear Low Density Polyethylene (LLDPE)
LL0410AA and LL0410KJ(contains slip agent) are LLDPE copolymers with butene as comonomer.They are suitable for blending with the conventional LDPE.In lean blends, they offer the following advantages compared to LDPE neat

High Impact Polystyrene (HIPS)
Two grades of HIPS which are produced in Iran are as follow : --HIPS7240 is a very high impact polystyrene used in the extrusion industry .This grade is designated to be diluted with crystal polystyrene. The good melt strength of this grade makes it particularly suitable for deep-draw thermoforming. It is available inwhite color. -----HIPS 8350 is a very high impact polystyrene used in the extrusion industry .This grade has an improved environmental stress crack resistance (ESCR) in comparison with standard high impact polystyrene grades.It is recommended for the production of packaging intended for products likely to cause stress cracking (e.g fats and oils).HIPS8350 retains good mechanical properties at low temperatures making this grade suitable for frozen food packaging and for the production of fridge liners in contact with HCFC expanded foam insulation.
Expandable Polystyrene (EPS)
Standard expandable polystyrene (EPS) is manufactured by the suspension polymerization method .
The polymerization is generally carried out in a batch process. Various grades of EPS supplied in free flowing beads containpentane (CFC free ) as a foaming agent . It is used for fast cycle low destiny block mold application with good surface finish.
EPS produced in two classes :
1)Standard grades
2)Flame retardant grades (FR)
Polyvinyl Chloride (PVC)
PVC is one of the two most important plastic materials available today. It is produced at NPC (BIPC site) by suspension polymerization process. PVC compounds of large extent of stabilizers and other additives are able to meet the requirements ofmany applications. --PVC grades produced by NPC with their

Epoxy Resin
Epiran resins (Epiran 1& Epiran 6 & Epiran10 & Epiran5 &Epiran5s) are standard unmodified Epoxy resins .Epiran 6 is a low molecular weight resin and Epiran 1 is a high molecular weight made from Bisphenol A and Epichlorohydrin. Epiran 10 is a high molecular weight resin which does not contain any diluent made from Bisphenol A and low molecular Epoxy resin using alloyingmethod. . .Applications:Epiran 6 is mainly used for compositions cold cured with polyamines and polyamids for manufacturing of adhesives and laminates used in electronics,radio engineering and compositions filled with metal powders,silica flour,graphite , etc. --Epiran 1 is mainly used as a base resin for manufacturing of varnishes cold cure with Aliphatic polyamines and polyaminoamides and adhesives hot-cured with acid anhydrides. --Epiran 10 is mainly used for powder paints cured with Aliphatic polyamines and polyaminoamides. Epiran 5 mainly used cold cure adhesive,varnishes and lutes ,as a binder in epoxy-glass laminate manufacturing and as encapsulating in electronics. --Epiran 5S mainly used cold cure
