- 一、聚四氟乙烯（PTFE）及多孔PTFE PTFE and porous PTFE
- 聚四氟乙烯（PTFE）是一种广泛应用于医疗、工业和高科技方面的多功能聚合物。 PTFE 的惰性使其对大多数化学品都不起反应，可在较高的温度环境 (260°C 持续)下加工和使用。
- 多孔 PTFE 具有优异的热学性能、电气性能、机械性能和化学性能，并对孔径大小、透气性、抗水压力和厚度有极高的控制。 PTFE 是对这些特殊性能有一种或多种要求的需求应用的理想选择。
- Polytetrafluoroethylene (PTFE) is a versatile polymer widely used in medical, industrial and high-tech applications. Inert PTFE could make it to most chemicals doesn't response, can be in high temperature environment (260 ° C for) the processing and use.
- Porous PTFE has excellent thermal, electrical, mechanical and chemical properties, as well as extremely high control over pore size, air permeability, water resistance and thickness.PTFE is ideal for applications that require one or more of these special properties.
- 二、聚四氟乙烯（PTFE）烧结多孔材料 Polytetrafluoroethylene (PTFE) sintered porous material
- 由于使用了不同的起始颗粒和生产工艺，SST能够为PTFE产品增加多孔性能。在制造过程中，SST的多孔PTFE在超过300°C的温度下进行烧结。这使产品具有高温和尺寸稳定性。因此，即使是最严苛的挑战也可以通过使用SST的PTFE多孔材料来满足。
- SST could increase the porosity of PTFE products due to the use of different starting particles and production processes. In the process of manufacturing, SST of porous PTFE in more than 300 ° C under the temperature of sintering. This gives the product high temperature and dimensional stability. Therefore, even the most demanding challenges can be met by using SST PTFE porous materials.
- Smart Membrane?-S Porous PTFE （REM 500x）。PTFE聚集体的坚固迷宫结构构建了疏水表面，可抵抗高水压并保持透气性，同时又可以起到过滤的效果，
- 在250至2,500 nm的宽波长范围内，亦具有超过98%的漫反射率。
