With chemical foaming agents for thermoplastic materials and intensive advice on their selection and use, Tosaf helps users meet the urgent demand from society and legislation for greater sustainability. Foamed plastics reduce the consumption of raw materials, which can also offer cost benefits, and their insulating properties can help reduce the use of energy. Sink marks can be avoided to a large extent, minimizing rejects even if there are high demands on surface quality. At the same time, foaming has no effect on recycling behaviour. Hence, the recyclability of the plastics in the materials cycle is maintained.
