Flexible slabstock foam: High-quality raw materials for slabstock production

Copied to clipboard

Slabstock production leads to foam blocks which may be transformed by cutting or other technologies to create a wide variety of foam products including mattress cores. We offer high-quality raw materials and fully formulated systems for this segment.

Flexible foam is formed by reacting polyol and isocyanate as key raw materials. This liquid reaction mix is poured onto a continuous laminator, resulting in a continuous rectangular foam block. After leaving the laminator, the flexible foam is cut into smaller blocks (up to 60 m) and stored for final curing and further processing into the required products. Most flexible foam blocks have a density between 15 and 60 kg/m³ and are used in the production of mattresses or furniture. Different foam types, such as conventional foam, high resilience (HR) foam, polyester-based foam and viscoelastic foam can be produced based on this technology. We offer a wide variety of raw materials, mostly polyols and isocyanates, for the production of slabstock foam. Suitable polyols are offered under the brands Desmophen®, Arcol®, Acclaim®, Hyperlite®, Multranol®, Softcel® and Ultracel®. A very recent innovation is cardyon®, a new polyol that contains CO2 in its backbone. We also carry isocyanates under the brand names Desmodur® and Mondur®.
