We specialize in giving XPE foam residues a second life. To do this we process cross-linked polyethylene foam (commonly abbreviated XPE, PEX or XLPE) as well as cross-linked polypropylene foam (XPP, PPX or XLPP) post industrial scrap.
XPE is a form of polyethylene with cross-links. XPE contains cross-linked bonds in the polymer structure, changing the thermoplastic to a thermoset. Cross-linking is accomplished during or after the extrusion of the material. XPE used for foaming is made from Linear Low Density Polyethylene (LLDPE). That, in combination with the closed cell structure, is why the specific weight of the foam is low.
XPP is a produced with a similar process by using polypropylene instead of polyethylene.
Of course we can always check if other materials are suited to be given a second life in our process. In order to check this we need to receive samples to test whether the material meets our requirements. This also applies to laminated XPE and XPP foams (with PE film, etc.).
Collection of foam
XPE foam is a voluminous product, making transport costly. Since 1990 Schmitz has developed several unique methods to collect the XPE foam residues at your factory at costs as low as possible.
Depending upon the quantity of XPE foam residues we offer several solutions in your factory:
- Press bales
- Shred the foam residues to flakes
- Load the foam residues in bags
- Load rolls
The choice of one of these solutions mainly depends on material thickness, density, quantity, scrap dimensions, previous treatments, etc. Also the distance to our factory plays an important role.
Because of the very specific nature of the XPE foam and our rework process we must apply certain XPE scrap acceptance conditions. Other materials that are mentioned below we can not use in our process:
- Contaminated or dirty materials;
- Material under the thickness of 2 mm.
- High density foams (> 80kg/m³) are ‘difficult’ for us.
- Laminated materials to be approved before shipment to Schmitz
