About FELS Kunststofftechnik
FELS Kunststofftechnik GmbH is a plastics manufacturer based in Lichtenau (North Rhine-Westphalia) specializing in masterbatches and additive concentrates. The company sees itself as a know-how center for innovative developments and customizes its products to customer requirements; new developments are qualified on site at the customer's premises. The portfolio includes color concentrates, antistatic agents, antifog additives, reinforcing agents, UV absorbers, desiccants, fillers, processing aids, antiblock and antislip agents, flame retardants as well as odor absorbers and odor blockers (FELSODUR and Felsolin product lines). The additives are used worldwide by customers for the production of blown and flat films and in injection molding, among other applications in plastics such as PE, PP, PS, PA and PC. The company's own research and development has, among other things, produced a halogen- and heavy-metal-free, highly transparent flame-retardant masterbatch (Felsoflamm M 230, DIN 4102/B1) as well as a surface treatment process for titanium dioxide that increases the hiding power of white masterbatches.
