供应美国杜邦Teflon® NXT 75Teflon® NXT 75这种树脂在高压和高温下的使用是有限的应用提供了高度的可焊性。
 
特富龙®NXT:
Manufacturing components of Teflon® is easier and more efficient than ever before, thanks to the high-strength welding and thermoforming capabilities of Teflon® NXT.元件制造业的Teflon®是比以往任何时候都更加容易和高效,感谢高强度焊接和热成型的Teflon®NXT的能力。因为组件建立更小的部分,而不是从大坯加工,可以减少加工时间和废品损失。
 
特富龙®NXT 75:
When properly processed, DuPont™ Teflon® NXT 75 exhibits the superior properties typical of the fluoropolymer resins: nonaging characteristics, chemical inertness, heat resistance, toughness and flexibility, low coefficient of friction, nonstick characteristics, negligible moisture absorption, and weather resistance.当正确处理,杜邦™特富龙®NXT的75,显示出典型的含氟聚合物树脂的优异性能:抗老化特性,化学惰性,耐热性,韧性和柔韧性,低摩擦系数的,不粘的特点,可以忽略不计的吸湿性,和耐候性。
In addition, this resin offers weldability, improved resistance to deformation under load, increased resistance to permeation of chemicals, and a higher dielectric breakdown voltage.此外,该树脂提供的可焊性,改进的耐负荷下的变形,提高耐化学品渗透,和较高的介电击穿电压。
This resin provides a high degree of weldability for applications where the use of elevated pressure and temperature are limited.这种树脂在高压和高温下的使用是有限的应用提供了高度的可焊性。
Typical End Products典型的终端产品:
Teflon® NXT 75 is a fine-cut resin designed for general compression molding of blocks and sheets and for use as a base resin for compounds.特氟龙®NXT 75是设计用于一般的压缩模塑的块和片材,以及使用的化合物作为基体树脂的树脂细切。It can be used for such applications as: seal rings, valve seats, bearing pads, linings, encapsulations, and as a base resin for filled compounds.它可以被用于这样的应用为:密封环,阀座,轴承瓦块,衬里,封装,和填充的化合物作为基体树脂。This resin is particularly useful in applications where welding of parts to other fluoropolymers such as PFA or standard PTFE is required, eg, fluid-handling systems.此树脂是特别有用的,其中的部件焊接到其他含氟聚合物如PFA或标准PTFE是必需的,例如,流体处理系统的应用中。
 
FDA ComplianceFDA合规性:
Properly processed products (sintered at high temperatures common to the industry) made from Teflon® NXT 75 resin can qualify for use in contact with food in compliance with FDA regulation 21 CFR 177.1550.正确处理产品在高温下常见的行业(烧结)由Teflon®NXT 75树脂可以有资格使用符合FDA法规21 CFR 177.1550与食品接触。
 
Processing处理:
Teflon® NXT 75 may be converted by compression molding techniques.特氟龙®NXT 75可能会被转换通过压缩成型技术。For instance, a preform is made at room temperature at the recommended pressure of 14 MPa (2,000 psi) and subsequently free sintered.比如,一种预成型体是由在室温下在建议的压力为14MPa(2,000 psi)的和随后的免费烧结。
Of particular significance for sheet molding is the fact that maximum density after sintering is reached at lower pressures when compared with nonmodified granulars as shown to the right.片材成型为具有特别意义的是一个事实,即在较低的压力下烧结后达到最大密度相比,未经修饰的颗粒剂时,如右图所示。This allows the production of larger sheets with existing equipment.这允许较大的片材与现
