Zonyl MP1100（4微米）

ZonylMP1100氟添加剂是一种白色的自由流动的PTFE粉末，旨在作为其他材料中的添加剂使用，以提供低表面自由能和其他氟聚合物特性。特别重要的是，已有发现证明它非常适用于油墨和涂层应用，这些应用对颗粒的均匀性有一定要求。与塑料和弹性体一起使用时，还可增强润滑性能和耐磨损性能。如果将其加入润滑剂中，可以增强严苛条件性能。Zonyl?MP1100可应用于–190到250°C(–310到480°F)的温度条件。

Teflon®PTFE 7A X

Polytetrafluoroethylene

DuPont Fluoropolymers

产品说明：

Teflon ® PTFE 7A X is a white powder with small particle sizeand high bulk density. The small particle size of Teflon ® PTFE 7AX helps to minimize voids even at relatively low molding pressures.High bulk density increases the size of moldings possible from agiven mold or press opening. Teflon ® PTFE 7A X is preferred forlarge moldings, such as billets, re optimum mechanical andelectrical properties. It is also used in a mixture with fillerswhen they are added to modify the mechanical properties ofmoldings. Properly processed products made from neat Teflon ®PTFE7A X provide the superior properties typical of the fluoroplasticresins: retention of properties after service at 260 °C (500 °F),useful properties at -240 °C (-400 °F), chemical inertness tonearly all industrial chemicals and solvents, and low friction andanti-stick surfaces. Dielectric properties are outstanding andstable with frequency and temperature. Molded products havemoderate stiffness and high elongation.

Teflon ® PTFE 7A X resists ignition and does not promote flame
spread. When ignited by flame from other sources, the contributionof heat is small and with little smoke. Statements, or data,regarding behavior in a flame situation are not intended to reflecthazards presented by this or any other material when under actualfire conditions.

Typical Applications
Many end products are fabricated from moldings of Teflon ® PTFE 7AX, including skived film and sheet, gaskets, packings, mechanicalseals, bridge or pipeline bearing pads, shaft bearings, electricalinsulators, piston rings, expansion bellows, diaphragms, andchemical linings. The use of fillers provides a wide choice ofmodified mechanical properties.
