Marine and offshore buyers increasingly specify plastic foam products and cushioning instead of metal, wood or glass. Here is where they are used, why they work, and what to watch out for.
Everything here can be checked on a real sample before you commit to a production order.
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 density 15 to 200 kg/m³; sheet and roll form; thickness 1 mm to 300 mm. Materials most often specified are Expanded Polystyrene, Expanded Polyethylene, Ethylene Vinyl Acetate, Polyurethane, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the marine and offshore sector the decision is usually driven by UV and salt resistance and impact strength, with buoyancy as a secondary requirement. Typical end uses include rope and netting, deck fittings, buoyancy floats.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| Polyurethane | 1.05-1.25 g/cm³ | 25-60 MPa | -30°C to 90°C |
| Expanded Polystyrene | 0.01-0.05 g/cm³ | 0.2-0.8 MPa | -40°C to 75°C |
| Ethylene Vinyl Acetate | 0.93-0.95 g/cm³ | 10-30 MPa | -40°C to 70°C |
Expanded Polyethylene is frequently the default selection here: EPE foam absorbs repeated impact, which is why it protects fragile goods in transit.
In the marine and offshore sector, these are the applications where this product has proven itself.
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.
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.
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.
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.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
