牌号简介	D/W 203是一种非烧结的聚四氟乙烯（聚四氟乙烯）薄膜，主要用于电气绝缘，特别是电线和电缆应用。聚合物是纤维化的，在机器方向上具有很好的强度。它具有聚四氟乙烯固有的优点：优异的耐化学性，极端温度范围从450华氏度到+500华氏度，摩擦系数低，优异的悬垂特性和不粘特性。D/W 203用于电缆绝缘、线束缠绕以及同轴电缆的介质。一旦烧结，它完全密封，以提供优良的电气绝缘性能，无与伦比的耐化学性和优良的热阻。杜瓦尔的非烧结聚四氟乙烯带具有良好的悬垂特性，使其能够顺利地符合复杂的形状。D/W 203可用于垫圈、膨胀节、阀门密封和隔膜应用。它是可用的无色素和色素，以匹配环评的颜色。烧结后强度高，适用于需要化学惰性和耐高温的场合。 D/W 203 is an unsintered PTFE (Polytetrafluoroethylene) film used primarily for electrical insulation, particularly for wire and cable applications. The polymer is fibrilated giving good strength in the machine direction. It has the inherent benefits of PTFE: exceptional chemical resistance, extreme temperature range from 450F to +500F, low coefficient of friction, excellent drape characteristics and non-stick properties. D/W 203 is used in cable insulation, harness wrap, and as the dielectric medium in coaxial cables. Once sintered, it seals completely to provide excellent electrical insulating properties, unsurpassed chemical resistance and excellent thermal resistance. DeWAL's unsintered PTFE tape has good drape characteristics allowing it to conform smoothly to complicated shapes. D/W 203 can be used for gaskets, expansion joints, valve seals and diaphragm applications. It is available unpigmented and pigmented to match EIA colors. It has good strength after sintering and is used where chemical inertness and high temperature resistance are needed.	Rulon® 945是一种黑色聚四氟乙烯基材料，在负载下磨损和变形非常小，非常适合要求高的热应用。事实上，它的变形是所有Rulon等级中最低的。它还具有良好的耐化学性和尺寸稳定性。Rulon® 945最适合用于坚硬的配合面，例如硬化钢基底，因为它具有中等的研磨性。它不适用于需要电绝缘性能的应用场合。 Rulon® 945 is a black PTFE-based material that has very low wear and deformation under load, making it ideally suited for demanding thermal applications. In fact, its deformation is the lowest of all Rulon® grades. It also possesses excellent chemical resistance and good dimensional stability. Rulon 945 is best suited for use against hard mating surfaces, like hardened steel substrates since it does have moderate abrasive qualities. It is not suitable in applications where electrically insulating properties are required.
