About Epic Polymer

Epic: engineered compounds for your part

Polymer Plast Zeinali Co. produces and supplies polymer compounds and granules under the Epic brand, for the automotive, home-appliance and electrical industries, construction, packaging and injection-moulded parts. Our job is not to sell “a granule” but to match the grade to the part and to the line it runs on.

What does compounding add to a polymer?

Compounding means melt-blending a base polymer (for example polypropylene) with fillers such as talc and calcium carbonate, or with fibres, and with additives such as stabilisers, flame retardants and masterbatch. The result is a grade tuned to stiffness, dimensional stability, colour and cost.

Four numbers that decide the grade

• MFI (melt flow index): how freely the melt flows into the mould. A higher MFI makes thin, complex moulds easier to fill, usually at the cost of impact strength.
• Ash: the percentage of mineral filler. It shifts stiffness, shrinkage and cost.
• Density: rises with filler and sets the weight of the part; for example the white 31 % filler grade is about 1.20 g/cm³.
• Impact strength vs. stiffness: the two are always traded against each other; we choose the grade from what the part does (bumper trim, switch plate, appliance housing…), not from one number.

From need to grade in four steps

1. Tell us the application and the process: injection, extrusion or blow moulding.
2. Tell us your priorities: strength, MFI, colour, filler content.
3. You receive the suggested grade or grades with an Epic datasheet. Datasheet values are typical, not guaranteed specifications, and the final choice rests with the technical specialist.
4. We arrange the sample and the next steps.
