What materials are the foams made from?

Our Azote® brand foams are all made from polyolefins, which is a family of synthetic plastic materials that includes low density polyethylene (LDPE), co-polymers of ethylene such as Ethylene-Vinyl Acetate (EVA), high density polyethylene (HDPE) and polypropylene (PP). In detail the raw materials by grade are:

Plastazote® LD = Low Density Polyethylene

Plastazote® MP = Metallocene Low Density

Polyethylene Plastazote® HD = High Density Polyethylene

Evazote® EV = Ethylene-Vinyl Acetate (High VA content)

Evazote® VA = Ethylene-Vinyl Acetate (Low VA content)

Supazote® EM = Ethylene-Methyl Acrylate

Propozote® PPA = Polypropylene

These raw materials then dictate how the foam will feel and perform, for instance our HD grade foams (HDPE) are rigid, absorb high levels of energy and have good temperature stability, whereas an EV grade foam (EVA) is soft, resilient but lacks the high temperature stability.

Our new range of engineering foams under the Zotek® F brand are produced from polyvinylidene fluoride (PVDF), a fluoropolymer which is a plastic relative of PTFE and has exceptional chemical, thermal and UV resistance.
