If you specify Polypropylene (PP) for anti-static and conductive component trays, a handful of properties decide whether the part survives forming and service. These are the values worth checking on every data sheet.
This guide is written for engineers, purchasers and project managers who need a practical answer, not a resin data sheet.
This category covers a family of products rather than a single item. In practice a buyer defines anti-static and conductive component 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 standard JEDEC and custom matrix layouts; carbon filled black grades; gauge 0.40 to 1.20 mm. Materials most often specified are Polypropylene, Polyethylene Terephthalate, Polycarbonate, Polystyrene, 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 component trays, device inserts, accessory blisters.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| Polystyrene | 1.04-1.06 g/cm³ | 30-50 MPa | -20°C to 70°C |
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°C |
Polypropylene is frequently the default selection here: PP is the lightest mainstream packaging resin and keeps its shape under repeated flexing.
These figures are typical for commercial grades and should be confirmed against the supplier's certificate for your specific lot.
Density 0.90-0.91 g/cm³, tensile strength 25-40 MPa, continuous service temperature -10°C to 100°C and melt range 160-170°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.
The route below is the one most factories use for this type of part.
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.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
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.
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.
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.
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.
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.
