If you specify Expanded Polyethylene (EPE Foam) plastic foam products and cushioning, a handful of properties decide whether the part survives in 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 plastic foam products and cushioning 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 anti-static and flame retardant grades; thickness 1 mm to 300 mm; density 15 to 200 kg/m³. Materials most often specified are Expanded Polyethylene, Expanded Polystyrene, Ethylene Vinyl Acetate, Polyurethane, 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 facade cladding, formwork panels, insulation boards.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Expanded Polyethylene | 0.02-0.05 g/cm³ | 0.3-1.5 MPa | -40°C to 80°C |
| Ethylene Vinyl Acetate | 0.93-0.95 g/cm³ | 10-30 MPa | -40°C to 70°C |
| Expanded Polystyrene | 0.01-0.05 g/cm³ | 0.2-0.8 MPa | -40°C to 75°C |
Expanded Polyethylene is frequently the default selection here: EPE foam absorbs repeated impact, which is why it protects fragile goods in transit.
These figures are typical for commercial grades and should be confirmed against the supplier's certificate for your specific lot.
Density 0.02-0.05 g/cm³, tensile strength 0.3-1.5 MPa, continuous service temperature -40°C to 80°C and melt range 110-130°C are the four values to circle on the data sheet. Everything else is secondary for most construction and building 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.
These are the criteria that actually predict whether the part will perform in service.
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.
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.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
