Polypropylene for compounding and masterbatch
Polypropylene for compounding is an input to someone else's product. A compounder adds talc, glass fibre, pigment or additives and sells the result against their own specification, so the base resin has to behave the same from one batch to the next. This page covers PP homopolymers and copolymers, in powder and pellet form, for filled compounds, modified grades and colour and additive masterbatch.
— REQUIREMENTS
What a base resin has to do
A compound recipe is tuned around its base polymer. If the flow or impact of that polymer drifts, the filler level, the additive dose and the moulder's settings all have to move with it. Masterbatch makers need a carrier that wets pigment well, stays processable at high loadings and melts readily into the customer's polymer. Form matters as well. Powder premixes evenly with fillers and additives before the extruder; pellets feed cleanly and make less dust. Some compounders want an unstabilised resin so they can set the whole additive package themselves.
— SELECTION
High-flow PP homopolymer, copolymer or powder
High-flow homopolymer is the usual masterbatch carrier and a flow modifier in compounds. The higher the flow, the more pigment or filler the carrier can take and still disperse. Metallocene homopolymers add low odour and low warpage.
Medium-flow homopolymer is the base for talc- and mineral-filled compounds where stiffness counts.
Impact copolymer is the building block for automotive and other technical compounds that need toughness in the cold. Ultra-high-flow copolymers also serve long-glass-fibre recipes.
Homopolymer powder mixes evenly with additives and fillers. Unstabilised powder needs your stabiliser package before it sees heat.
For letdown, pick a carrier whose melt flow is at least as high as the host polymer's, so the masterbatch mixes in evenly. On unstabilised powder, the data sheet may report properties measured after pelletising with additives; your compound will not match them exactly.

— NEED HELP CHOOSING?
Not sure which grade fits?
Send us your recipe type, filler or pigment loading, preferred form and current base resin.
— PROCESSING
Feeding powder and pellets
Powder and pellets need different feeders. Powder also needs closed handling: fine polymer dust in air can ignite, as the safety data sheets point out. Keep unstabilised powder away from heat until it is compounded. Tell us your extruder, feeding set-up and target filler or pigment loading, and we will match flow and form.

— DOCUMENTATION
Documentation that passes down the chain
Regulation (EU) No 10/2011 requires a declaration of compliance for intermediate products as well as finished articles, at every stage before retail. A masterbatch or compound meant for food contact therefore carries its own declaration, supported by the producer's declaration for the base resin. For automotive compounds, ask for the grade's IMDS reference. For medical or pharmaceutical end uses, tell us at the start, because producers restrict some grades from those uses.
