polyurethane
In chemical terms, polyurethanes are plastics or synthetic resins made by the polyaddition polymerisation of dialcohols (diols) or polyols with polyisocyanates (–NH –CO –O–). Polyurethane offers are wide, very diverse range of properties and is often called the “all-rounder” in dispensing and metering technology because of its flexibility. Depending on the level of cross-linkage and/or use of isocyanate and OH components, duroplasts, thermoplasts and elastomers can be created. In industry, polyurethanes are one of the most frequently used two-component materials.
key properties
- Polyurethanes are very easy to handle and take on protective functions similar to epoxies and silicones.
- Because of their broad range of applications, polyurethanes are often used in dispensing and metering technology as a functional material in upholstered furniture or sports kit, in electronics manufacture for e.g. control devices or capacitors and as an assembly adhesive.
- With modifying additives, the properties of this material can be made to vary widely.
- ailor-made plastics are the result: hard, brittle, soft, elastic, with varying viscosities, from fluid to viscous (thick paste).
