TAPTITE 2000 ® is a thread-tapping screw with outstanding mechanical, fastening and ergonomic characteristics. Compared with conventional screws, with TAPTITE 2000 ® you can reduce your overall fastening costs by up to 85%, partly because the cost of manufacture is drastically reduced: Many steps of the process can simply be omitted.

These screws have a triangular shank that presses tightly as it forms threads, so screws resist loosening in soft metals such as brass, aluminum, and copper. They’re also known as Taptite® screws. Made from steel, they're zinc-plated steel to resist corrosion in wet environments. Length is measured from under the head.

2025年3月21日 · Tap-Flex® Thread-Forming Structural Screws are thread-forming, dual heat treated self-tapping fasteners that provide the strength, ductlity, and resistance to embrittlement failures required in critical curtain wall and dissimilar metal applications.

The EJOT self-tapping screws form the thread in a pre-drilled hole. They feature a coarse or fine pitch thread. At the bottom of the screw, there is a dog point or a rolled point, depending on the application. The self-tapping screws are completed by an optional pre-assembled sealing washer. » Further information

2023年11月1日 · 聚酰胺类热塑性弹性体（tpae）是一种尼龙型的tpe，最早在1979年由德国赫斯化学公司引入市场。 紧接着，瑞士EMS化学公司、法国阿科玛公司（Pebax系列）、德国贏创公司和日本油墨公司等也陆续开发出了相应TPAE产品。

根据聚酰胺热塑性弹性体合成所需的原料， 其合成方法可以分为二元酸法和异氰酸酯法。采用二元酸法， tpae 是由端羧基脂肪族聚酰胺嵌段与端羟基聚醚二元醇通过酯化反应制备的。异氰酸酯法是以半芳酰胺为硬段， 脂肪族聚酯、聚醚或聚碳酸酯作为软段。

热塑性聚酰胺弹性体（TPAE）是由高熔点结晶性硬段（聚酰胺）和非结晶性软段（聚酯或聚醚）组成，其性能取决于硬段类型及两种嵌段的长度。 通过选择和控制嵌段类别，其力学、热和化学性能可在很大范围内变化。 文章简述TPAE的合成方法和成型工艺。
