Foamed Plastics - an overview | ScienceDirect Topics
Foamed plastics are a new type with the properties of lightweight, heat preservation, sound absorption, and quakeproof. This material can be used in wall and cold storage insulation, and can also be used to make sandwich board.
发泡塑料 - 百度百科
发泡成型是使塑料产生微孔结构的过程。 几乎所有的 热固性 和 热塑性塑料 都能制成泡沫塑料，常用的树脂有 聚苯乙烯 、 聚氨酯 、 聚氯乙烯 、 聚乙烯 、 脲甲醛 、 酚醛 等。 按照泡孔结构可将泡沫塑料分为两类，若绝大多数气孔是互相连通的，则称为 开孔泡沫塑料；如果绝大多数气孔是互相分隔的，则称为 闭孔泡沫塑料。 开孔或闭孔的泡沫结构是由制造方法所决定的。 (1) 化学发泡。 由特意加入的化学发泡剂，受热分解或原料组分间发生化学反应而产生的气体，使塑料熔体充 …
泡沫塑料 - 维基百科，自由的百科全书
泡沫塑料（英语：foamed plastic 或 polymeric foam），俗稱保麗龍（亦稱保利綸，香港俗稱發泡膠）。是以气体物质为分散相、以固体树脂为分散介质，所组成的“分散体”，它是一类带有许多气孔的塑料；口语可称之为 泡沫材、发泡材。
泡沫塑料 - 百度百科
泡沫塑料是由大量气体微孔分散于固体塑料中而形成的一类高分子材料，具有质轻、隔热、吸音、减震等特性，且介电性能优于基体 树脂，用途很广。 几乎各种塑料均可作成泡沫塑料，发泡成型已成为塑料加工中一个重要领域。 又称微孔塑料。 整体布满无数互相连通或互不连通的微孔而使表观密度明显降低的塑料。 具有质轻、绝热、吸音、防震、耐潮、耐腐蚀等优点。 按其泡孔结构可分为闭孔、开孔和网状泡沫塑料。 闭孔泡沫塑料所有泡孔几乎都是不连通的。 开孔泡沫塑 …

Polymeric foam - Wikipedia
A polymeric foam is a special foam, in liquid or solidified form, formed from polymers. [1] Examples include: ^ Taskin, Omer Suat (2023). "Polymeric Foams: Materials, Technology, and Applications". In Gupta, Ram K. (ed.). Polymeric Foams: Applications of Polymeric Foams. Vol. 2.
Plastic - Foaming, Manufacturing, Properties | Britannica
Oct 17, 2024 · Foams, also called expanded plastics, possess inherent features that make them suitable for certain applications. For instance, the thermal conductivity of a foam is lower than that of the solid polymer. Also, a foamed polymer is more rigid than the solid polymer for any given weight of the material.
