  • Patent number: 11661373
    Abstract: To provide a method for recycling a solar cell module glass, which enables development of other novel applications of a waste glass of a solar cell module while controlling an elution amount of Sb from the waste glass into water. Disclosed is a method for recycling a solar cell module glass, the method comprising: grinding a solar cell module glass into a glass powder; adding at least one foaming agent selected from SiC, CaCO3 and a seashell, and a particular inhibitor to the glass powder to produce a mixture; and heating the mixture to 700 to 1,100° C. to produce a foam glass.

  • Patent number: 9120920
    Abstract: Provided is a polymer composition including (A) an ionomer containing an ethylene/?,?-unsaturated carboxylic acid copolymer and an ethylene/?,?-unsaturated carboxylic acid/?,?-unsaturated carboxylic acid ester terpolymer, and (B) a propylene-based polymer, wherein the mass of constituent units derived from the ?,?-unsaturated carboxylic acid ester is from 1 to 4.5% by mass of the entire mass of the ionomer. Through this, a high seal strength may be obtained in a high-temperature range when forming a lock seal, while a high seal strength, as compared with the related art, can be stably obtained over a wide temperature range with a temperature dependence suppressed when forming a peelable seal.

  • Publication number: 20060057318
    Abstract: The present invention relates to a multi-layer structure constructed of two or more layers including a potassium ionomer layer (X) having a low surface resistivity and a layer (Y) comprising a polymer material having a high surface resistivity like LLDPE as a surface layer, where the static charge decay characteristics of the layer (Y) is improved. This type of two layer or three layer structure having the layer (X) as its intermediate layer or another surface layer gives good slip characteristics, abrasion resistance, and dust-free characteristics, and hence is useful for packaging materials, such as films, sheets and containers.
