If you specify Polycarbonate (PC) for industrial dunnage and handling trays, a handful of properties decide whether the part survives forming and service. These are the values worth checking on every data sheet.
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 industrial dunnage and handling trays 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 stack and nest geometry; gauge 1.5 to 8.0 mm; ESD and conductive grades. Materials most often specified are High Density Polyethylene, Acrylonitrile Butadiene Styrene, Polycarbonate, Polyethylene Terephthalate, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the electronics and electrical sector the decision is usually driven by ESD protection and dimensional accuracy, with cleanliness as a secondary requirement. Typical end uses include device inserts, accessory blisters, battery packs.
The table below summarises the values that usually decide the material choice.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polyethylene Terephthalate | 1.35-1.40 g/cm³ | 50-70 MPa | -40°C to 70°C |
| Acrylonitrile Butadiene Styrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 80°C |
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°C |
Polycarbonate is frequently the default selection here: PC replaces glass where impact safety matters, but it needs a hard coat for abrasion resistance.
The table below summarises the values that usually decide the material choice.
Density 1.20 g/cm³, tensile strength 55-70 MPa, continuous service temperature -40°C to 120°C and melt range 260-300°C are the four values to circle on the data sheet. Everything else is secondary for most electronics and electrical projects.
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.
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.
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.
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.
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.
If you are planning a new electronics and electrical 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.
