Materials

HDPE recycled granules, high density polyethylene

HDPE is the material for parts that have to survive impact, moisture and cold. We source high density polyethylene recycled granules in a range of colours and deliver across Serbia.

Applications

What HDPE recycled granules are used for

High density polyethylene is chosen where the part has to survive rough handling. Unlike polypropylene, HDPE keeps its toughness as the temperature drops, so it is used for anything that stands outdoors or works in a cold plant.

bins, drums, jerrycans and liquid containers
transport packaging that is stacked and moved full
pipe and fittings, including buried runs
pallets, crates and municipal equipment
film and bags on extrusion, where tear strength matters

HDPE is often taken as a replacement for PP on the same part, once it turns out the part cracks in the cold. If that is happening to you, it is worth trying a sample of HDPE recycled granules before you change the tool.

Machines

What HDPE runs on

HDPE is processed by injection moulding, extrusion and blow moulding. On blow moulding and on pipe extrusion, batch consistency matters more than on injection, because a difference in flow feeds straight through to wall thickness.

On injection HDPE needs somewhat more pressure than PP at the same thin wall, and it shrinks more on cooling. If you are switching from PP to HDPE in the same tool, expect the part dimensions to change.

As with any recycled granule, it pays to set the parameters on a sample. We send samples before an order for exactly that reason, so the trial runs on your machine rather than on your first delivery.

Properties

What HDPE gives the finished part

HDPE is the stiffer, denser branch of polyethylene, and compared with PP it gives a part that takes impact better, especially in the cold.

good impact resistance, including at low temperature
takes up almost no moisture, so it suits containers and outdoor parts
good chemical resistance, including detergents and most solutions
softer surface than ABS, so it scratches more easily
harder to bond and to print without surface pre-treatment

Actual flow and density depend on the batch. Rather than publishing figures we cannot guarantee for every delivery, we tell you what the specific batch carries when we quote it.

Before we quote

What to tell us before we price it

For HDPE recycled granules, tell us the machine, the part, the colour and the quantity. It particularly helps to know whether the part works outdoors or in the cold, because that narrows the batch selection.

If you currently run virgin polyethylene and are considering a switch, say so. The change is not always one for one, and it is better discussed before the order than after it.
