Abstract:
The present invention relates to a process for producing foam mouldings, comprising a) providing a first amount of expandable foam particles; b) providing a second amount of expandable foam particles; c) preparing a physical mixture on basis of said first and second amount of foam particles; d) introduction of the mixture of step c) into a mould and sintering under pressure and heat, wherein the chemical origin of the first amount of expandable foam particles differs from the chemical origin of the second amount of foam particles, the process further comprising the presence of a coating in the mixture before the introduction of the mixture into the mould.
