High Density Polyethylene (HDPE) and Acrylonitrile Butadiene Styrene (ABS) are the two most quoted options for plastic extrusion profiles in energy and renewables projects. Both are widely available, but they behave very differently once they are in service.
The notes below come from day to day production and export work with overseas buyers.
This category covers a family of products rather than a single item. In practice a buyer defines plastic extrusion profiles by three things: the base resin, the format or dimension, and the performance or certification level it has to meet. Typical options in this category include custom cross section up to 300 mm; cut lengths from 50 mm; rigid, semi-rigid and flexible compounds. Materials most often specified are Polyvinyl Chloride, Acrylonitrile Butadiene Styrene, High Density Polyethylene, Thermoplastic Elastomer, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the energy and renewables sector the decision is usually driven by UV durability and flame retardancy, with electrical insulation as a secondary requirement. Typical end uses include cable jacketing, battery housings, solar junction boxes.
These figures are typical for commercial grades and should be confirmed against the supplier's certificate for your specific lot.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polyvinyl Chloride | 1.38-1.45 g/cm³ | 40-55 MPa | -10°C to 60°C |
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°C |
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°C |
High Density Polyethylene is frequently the default selection here: HDPE combines toughness with chemical inertness, which is why it dominates pipe and tank markets.
High Density Polyethylene grades offer high impact strength even at low temperature, while Acrylonitrile Butadiene Styrene brings high impact toughness. For energy and renewables service the difference shows up in chemical resistance and in the long term behaviour under load.
In short: choose the first option when stiffness, heat and dimensional stability dominate; choose the second when impact, cost and processing speed matter more.
Beyond the base resin, most suppliers offer UV stabilised, food contact, flame retardant, anti-static and recycled content versions of the same product. Ask which additive package is included, because it is often the difference between a part that lasts three years and one that lasts ten.
Processing method drives both cost and performance, so it should be fixed early in the design.
Secondary operations such as printing, welding, machining and assembly are often cheaper to do in the same factory, and they reduce the risk of mismatch between components.
Work through these points in order and most specification mistakes disappear.

Standard production tolerance follows the relevant ISO or DIN tolerance class for the process; tighter tolerances are possible after machining or grinding, but they add cost. Define the tolerance only on the functional dimensions.
A new tool typically takes 25 to 45 days depending on cavity count and complexity, followed by T1 samples within one week. Existing tools can usually start production within 10 to 15 days of order confirmation.
Standard packing is export cartons on fumigation-free pallets, with custom labelling, barcode and retail packing available. We also handle consolidated containers and door to door delivery.
Yes. Standard samples are normally free of charge and shipped within three working days; custom samples are charged at cost and credited against the first production order.
Yes. {mat1} is one of our regular materials for this item, and we can supply virgin, modified and certified grades with full traceability. Material certificates and test reports are issued per batch.
