Raw Material Source
Within each of the Foam materials, there are multiple raw material content options available to further customize a material.
If only the general raw material type is known, then the default selection should be left unchanged.
- Ethylene-vinyl acetate (EVA), fossil fuel based is the default selection and should be selected unless one of the other process options are more appropriate.
- Ethylene-vinyl acetate (EVA), recycled should be selected when using EVA raw material that is known to have 100% recycled content. If the raw material content is a blend of recycled and virgin EVA, then a custom material blend should be created using the known ratio of recycled to virgin EVA.
- Bloom EVA {Algix}, US should only be selected when the raw material is known to be Bloom EVA from Algix.
- Expanded Polystyrene (EPS), for foam is the default selection and should be selected when using EPS where the granules are frothed, treated in a block foaming machine, cutted and piled.
- High density polyethylene (HDPE) resin, fossil fuel based, for foam should be selected for all High Density polyethylene foam materials.
- Polyethylene (LDPE) resin, fossil fuel based, for foam should be selected for all Low Density polyethylene foam materials.
- Polyethylene (PE), recycled, for foam should be selected when using recycled PE foam materials. Applies to both High density polyethylene (HDPE) and Low density polyethylene (LPDE) recycled foam materials.
Thermoset polyurethane (PU), fossil fuel based, for foam is the default selection and should be selectedunless it is known that one of the other process options are more appropriate.
Polyurethane (PU) foam {Great Lotus}, 20% biobased (soy polyol) should be selected when using “Natural 20” partially biobased polyurethane from Great Lotus.
- FATES™ Polyurethane (PU) foam {Evoco}, 80% biobased should be selected when using Evoco’s FATES™ PU foam. FATES™ is a patented plant-based flexible foam that is GreenCircle and USDA BioPreferred certified, with up to 80% plant-based content.
- Polyvinyl chloride (PVC), fossil fuel based, for foam is the default selection and should be selected for all Polyvinyl chloride (PVC) foam materials.
- Thermoplastic elastomer (TPE), fossil fuel based, for foam is the default selection and should be selected for all Thermoplastic elastomer (TPE) foam materials
- Typical EVA shoe compound is the default selection and should be selected when using the Typical EVA shoe compound material.
