Polystyrene (PS / HIPS) and Acrylonitrile Butadiene Styrene (ABS) are the two most quoted options for electronic plastic housings and enclosures in construction and building projects. Both are widely available, but they behave very differently once they are in service.
Use it as a working checklist when you write your next enquiry.
This category covers a family of products rather than a single item. In practice a buyer defines electronic plastic housings and enclosures 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 wall thickness 1.2 to 3.0 mm; EMI and anti-static grades; textured and soft touch finishes. Materials most often specified are Polycarbonate, Polypropylene, Acrylonitrile Butadiene Styrene, Polystyrene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the construction and building sector the decision is usually driven by weather resistance and fire classification, with long service life as a secondary requirement. Typical end uses include drainage pipe, facade cladding, window profiles.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Acrylonitrile Butadiene Styrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 80°C |
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°C |
| Glass Filled Nylon | 1.36-1.38 g/cm³ | 130-190 MPa | -40°C to 150°C |
Polystyrene is frequently the default selection here: HIPS is the default thermoforming sheet for food packaging and appliance liners.
Polystyrene grades offer rigid and glossy, while Acrylonitrile Butadiene Styrene brings high impact toughness. For construction and building service the difference shows up in chemical resistance and in the long term behaviour under load.
The practical decision usually comes down to the service environment: temperature, chemical exposure and expected lifetime.
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.
Each step below has its own control points, and skipping one of them is where most defects start.
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.
Use this checklist when comparing two or three supplier quotations.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
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.
For standard sizes and colours the minimum is usually one pallet or one production run; for custom tooling the economic minimum depends on the tooling cost amortised over the expected volume. Send us your annual volume and we will calculate the break even point.
We can provide ISO 9001 quality system documentation, material certificates, RoHS and REACH statements, and where applicable food contact, flame retardancy or drinking water approvals. Tell us your target market and we will match the document set.
Colour is controlled with a masterbatch reference approved by the customer, and every production lot is checked against the approved sample under standard lighting before shipment.
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.
If you are planning a new construction and building project, send us your drawing, annual volume and target properties, and we will come back with a material proposal, a tooling plan and a budget quotation.
