常用材料
氯丁橡膠 CHLOROPRENE (CR)
氯丁二烯,也被稱為氯丁橡膠,聚氯丁二烯,和CR橡膠。這種材料沒有什么特殊屬性,但可以適用于絕大多數(shù)使用場景。其具有良好的耐外性能、良好的耐熱性能、良好的彈性和柔韌性以及耐油性能,當(dāng)不需要在特別條件下使用時(shí),該材料將被認(rèn)為可以是全能墊片材料。
Chloroprene, also called neoprene, polychloroprene, and CR rubber. The material does not excel in any unique way except that it endures most challenges well. With good outside resisting properties, a good thermal resistance, good mechanical traits such as elasticity and flexibility as well as a conditional oil resistance the material is to be considered an allround gasketing material when no extreme requirements are needed.
氯丁橡膠是一種非常常見的工業(yè)橡膠,可用于傳統(tǒng)工業(yè)的各種產(chǎn)品。材料制成墊片、密封、密封條和電纜。
Chloroprene rubber is a very common industrial rubber that is used for a great variety of products for traditional industry. The material is produced into gaskets, seals, seal strips and cable-throughs.
這種材料具有絕緣性能,且因其低易燃性能而造成小的火災(zāi)危險(xiǎn),非常適合作為電氣絕緣。常用于外殼中,如機(jī)柜中的密封條和傳統(tǒng)的機(jī)械工業(yè)產(chǎn)品。
The material is well suited as an electrical insulation because of its insulating properties and posing small fire-hazards because of its low flammability rate. Commonly used in enclosures, as seal strips in cabinets and traditional mechanical industrial products.
歷史上,氯丁橡膠是第一個(gè)真的有效的合成橡膠材料,在1930年由杜邦公司以氯丁橡膠的名義發(fā)明出來。在氯丁橡膠之前,只使用了從橡膠樹中回收的副橡膠或天然橡膠。由于橡膠樹的生產(chǎn)能力有限,人們擔(dān)心生產(chǎn)速度和不可靠的供應(yīng)鏈。不斷增長的汽車工業(yè)對(duì)橡膠的需求巨大,人們擔(dān)心原材料的潛在短缺。
Historically the chloroprene rubber the first real functioning synthetic rubber material that’s been invented the year 1930 under the name Neoprene by the company DuPont. Before Neoprene only para- or natural rubber was used that’s recovered from rubber trees. There was concern for the production rate and the unreliable supply chain because of the rubber trees limited production capacity. Rubber was in huge demand for the continuously growing automotive industry and there was concern for the potential shortage of the raw-material.
