A foamable polypropylene composition, and foamed polypropylene and a preparation method therefor are provided. The polypropylene composition comprises polypropylene, a polypropylene modifier, a foaming agent, and an optional nucleating agent. A preparation method for the polypropylene modifier comprises: enabling polar monomer grafted polypropylene to be in contact with a component A to react and carrying out extruding pelletizing, wherein a polar monomer in the polar monomer grafted polypropylene can chemically react with the component A; the polar monomer is selected from at least one of dimethylamino methacrylate, epoxy acrylate, trimeric acrylic isocyanurate, and acrylamide; and the component A is selected from at least one of polyisocyanate, polyethylene oxide, and an amido-containing substance. The foamed polypropylene has an obtained foaming ratio of 12 times or more, and also has high tensile and flexural properties.

Compositions with improved flame properties and with improved melt dripping properties can include a first polymer and a reactive component. The first polymer may be nylon or polyethylene terephthalate (PET). The composition can be formed into fibers and woven into a fabric. Crosslinking of the first polymer or of the first polymer and the reactive component can provide the improved properties.
