PP recycled granules, polypropylene

Polypropylene covers the widest range of finished parts of anything we supply. Injection moulders working on packaging and technical mouldings ask for it most, because it fills the tool well and holds up over long runs.

• transport and storage packaging: crates, boxes, lids
• bins, tubs, baskets and garden ranges
• closures and caps, where a hinge has to survive many cycles
• parts for white goods and vehicle interiors
• profiles, tapes and pipe on extrusion

If the part meets chemicals, detergents or fats in use, PP is usually the first material to consider. It resists a wide range of compounds that would attack other polymers.

Of everything we source, PP gives the lightest part for the same volume. On packaging and on parts shipped in quantity, that shows up directly in freight cost.

• good chemical resistance to fats, alkalis and most acids
• takes repeated flexing at the same point, so it suits integrated hinges
• colours well and takes masterbatch
• gets more brittle in the cold than polyethylene, so for parts working at low temperature it is worth checking whether HDPE is the better choice

Exact flow and density figures depend on the batch we source. We do not publish numbers we cannot stand behind for every delivery. Instead we tell you what a given batch carries when we quote it.
