The Introduction of Low Density ePTFE Film

Views: 101     Author: Site Editor     Publish Time: 2022-01-30      Origin: Site

Foreverseal is a privately owned company with a very stable financial background, who is a professional manufacturer and exporter of high quality PTFE TAPE from Jun 2009. With significant investment in both R&D for all production line, Foreverseal has already introduced automatic machines to improve the work efficiency and product quality from 2014. Our premium PTFE TAPE have obtained UL, CE, WRAS, RoHS...Stable and good quality lead us to keep long and standing business relations with old clients and get more new clients from middle & high quality markets. Following, we will introduce our low density ePTFE film product.

 

We can call Eptfe film as unsintered PTFE films. Unsintered extruded PTFE film is produced by a paste extrusion process, called “extruded” PTFE tapes and films too. In order to pursue the high quality PTFE films,all the production process is completed in the constant temperature and 100,000 grade dus-free workshop.

Characteristics

Low density PTFE film & tape produce micropore through stretch and under a certain specific and tightly controlled conditions to achieve low dielectric constant and high tensile strength.

It's light, soft, flame retardant. Besides, low dielectric constant makes low density PTFE tapes can be applied in high frequency microwave coaxial cable especially in data transfer,militarty and medical field.
