  1. SIBUR develops new polymer grade: Sibex 3DF

    ... acidic and alkaline environments and is less economical. Compared to polypropylene, all these materials have a relatively low resistance to repeated bending loads, i.e. they snap under frequent strain. The innovative composition of polypropylene-based Sibex 3DF not only overcomes the traditional drawbacks of plastics used in FDM, it also prevents polypropylene shrinkage. For a long time, polypropylene’s high shrinkage prevented it being used in FDM 3D printing, as parts could not be produced to the ...
