The World’s Softest Cross-linked Polyolefin Foam

Alveosoft is the softest foam product featuring a high compressibility and shape recovery, combined with excellent durability. Alveosoft has a partly open-cell structure that is more than ten times softer than other well-known closed-cell polyolefin foams and comes closer to the range of soft PVC, PUR and EPDM foams.

Alveosoft Details

Alveosoft is a continuous roll foam with process skins on both sides. The product range covers quick and slow recovery grades in a range from 2–12 mm and different FR variants (DIN 4102 B2, ISO 3795 FMVSS 302, NF P 92-501 M1).

Highly Resistant

Alveosoft repels water, and has a long life in humid conditions. It will not decay or rot, and does not deteriorate when in contact with chemical substances.

Easy To Compress

Excellent for sealing against dust, draught, noise, and cold, Alveosoft conforms well to irregular gaps and seals without deformation of adjacent structure.

Environmentally Neutral

Alveosoft contains no heavy metals, no dangerous additives (i.e. plasticizers), and is free of CFC’s and HCFC’s.
