Materials

PS recycled granules, polystyrene

Polystyrene is chosen when the part has to be stiff, dimensionally stable and good to look at. We source PS recycled granules on request and deliver across Serbia.

Applications

What PS recycled granules are used for

Polystyrene shows up in processing as two families that behave quite differently. General purpose polystyrene gives a hard, clear part, while the impact modified grade, usually called HIPS on the shop floor, gives a matt part that takes a knock.

food packaging, cups, trays and lids on thermoforming
housings and internal linings for appliances
decorative and finishing strips, frames and profiles
parts that need an accurate dimension with little movement over time
sheet that goes on for thermoforming

With polystyrene it matters more than with PP or HDPE to know in advance which family you need. General purpose and impact grades are not swapped for one another without consequences for the finished part.

Machines

What PS runs on

PS is mostly processed by injection moulding and sheet extrusion, and the sheet then goes to thermoforming. The material is easy to work and gives a clean surface, so it suits parts that are not painted afterwards.

On injection, polystyrene cools quickly and holds dimension well, but it is sensitive to internal stress. If the part has sharp transitions, that is where cracks appear first, so it is worth checking on a sample.

With recycled polystyrene the spread of properties between batches tends to be wider than with PP and HDPE. That is why we always recommend a trial before a larger order.

Properties

What polystyrene gives the finished part

Polystyrene is the stiffest of the materials we source as recycled granules. That is both its strength and its limit.

high stiffness and good dimensional stability
clean surface that needs no further finishing
colours easily and holds the shade well
the general purpose grade is brittle and does not take impact, while the impact grade fixes that but loses clarity
weaker chemical resistance than PP and HDPE, especially against solvents and fats

Colour and exact properties depend on the batch we source. For a specific delivery we tell you what that batch carries, rather than relying on general figures.

Before we quote

What to tell us before we price it

With PS recycled granules the first question is whether you need the general purpose or the impact modified grade. If you are not sure, describe the part and tell us whether it is allowed to be brittle.

After that we need the machine, the colour, the quantity and the lead time. If the shade matters for the finished part, say so up front, because with polystyrene batch colour can vary noticeably.
