  • Product Overview

Expanded PTFE sealing tape, also known as expanded PTFE interface tape, is a general purpose gasket that can be used safely and effectively in highly corrosive and pure applications in a variety of flanges such as plastic and stainless steel, enamelled, etc. It is a continuous strip of 100% PTFE white pure PTFE with no fillers. It is a continuous strip of 100% PTFE white pure PTFE without any fillers for high safety. Its microcellular structure has lower compression creep and cold flow properties than other PTFE products. Its flexibility, compressive resilience, creep resistance, high and low temperature resistance, excellent corrosion resistance, non-ageing and self-lubricating properties make it an excellent seal, and it comes with a backing that can be made into any shape on site without prior preparation, making it easy to use and install. Compared to ordinary stamped gaskets, it saves delivery time and edge costs. It is an ideal sealing material for chemical, pharmaceutical, petrochemical, food and beverage, electronic, electric power, metallurgical and marine industries.

四氟垫片规格在-100℃~100℃之间能够具有良好的冲击韧性能够加工成不同形状的四氟制品,还能够和其它材料组合运用如制成四氟包覆垫片,缠绕垫片,或作为金属类垫片的贴层,如金属齿型组合垫和金属波齿复合垫片

膨胀四氟 板又叫膨体聚四氟乙烯板,软四氟板是由百分百PTFE的膨体聚四氟乙烯材料经特殊工艺彭化为的,膨体四氟材料(eptfe)它是将聚四氟乙烯彭化成为一种具有坚毅而多孔性的独特材料,它高度纤维化,这种材料不但保持了聚四氟乙烯本身独特的性能的化学稳定性(不受一般化学品的影响);低的摩擦阻力;较广阔的操作温度;不会老化耐用;如今它多纤维的结构使其作为密封产品具有超乎想象的坚韧性,更为重要他从根本上解决了其他类型四氟密封材料的通病--蠕变和冷流,四氟垫片厂家与纯四氟板和填充四氟板相比性能大幅改善,此外,便于切割,便于安装,经久耐用等特性使它可在几乎所有的密封场地中得到实践应用。这无疑是一项了不起的改革。
