Abstract: A foaming additive and a catalyst additive may be used to foam polymeric materials having a low melt flow rate. The foaming additive may include a blowing agent and a hydrophilic component, and the catalyst additive may include a catalyst and a hydrophilic component. Since both the blowing agent and the catalyst are initially combined with a hydrophilic component, the blowing agent and the catalyst are able to find each other easier after being added to the polymeric materials. This makes it simple and economical to make low density foamed materials using polymeric materials having a low melt flow rate.

Abstract translation: 可以使用发泡添加剂和催化剂添加剂来发泡具有低熔体流动速率的聚合材料。 发泡添加剂可以包括发泡剂和亲水组分，并且催化剂添加剂可以包括催化剂和亲水组分。 由于发泡剂和催化剂两者最初与亲水性组分组合，所以发泡剂和催化剂在添加到聚合物材料之后能够更容易地发现。 这使得使用具有低熔体流动速率的聚合材料制造低密度发泡材料变得简单和经济。

Abstract: A process for the production of expanded beads, including kneading a base resin containing a polypropylene resin and having a tensile modulus of at least 1,200 MPa together with a mixture of a coloring agent and a thermoplastic polymer having a tensile modulus lower than that of the base resin to form a kneaded mixture including a matrix of the base resin and a multiplicity of domains dispersed in the matrix and each containing the thermoplastic polymer and the coloring agent. The kneaded mixture is formed into resin particles, then treated with an organic peroxide to modify surfaces of the resin particles therewith. Foaming and expanding of the surface-modified resin particles gives expanded beads having an inside region surrounded by a surface region. The heat of fusion of a high temperature peak of the surface region is lower than that of the inside region.

Abstract: A molded closure for a liquid container comprising a thermoplastic elastomer and a blowing agent. The molded closure is particularly suitable for use as a synthetic wine cork in a wine bottle. The molded closure does not permit passage of oxygen into the container, does not absorb oxygen from the contents of the container, can be removed from the container using a corkscrew without significant expansion, crumbling or disintegration, does not significantly taint a liquid in the container, permits the container to be placed horizontally immediately after insertion of the molded closure, and can permanently retain printed matter on its surface.
