The Introduction of ePTFE Film

Views: 100     Author: Site Editor     Publish Time: 2022-02-01      Origin: Site

Founded in 2009, Foreverseal is one of the world's largest manufacturers of high quality PTFE tape. More than 10 years development, foreverseal has successfully upgraded from the PTFE tape to the manufacturing of high-end ePTFE film industry. 

 

In 2019, we have imported of the world-class precision calender and stretching equipment; and established PTFE film test laboratory; The expert who have engaged in the Fluorine industry more than 30 years led the whole technical team, providing us a strong technical for PTFE film and guide us to the new area of PTFE products in the future!  

 

PTFE is a special material, let’s work together to make it in a wider range of uses to fulfill the customers’ need and even the requires of the whole social development! Today, we will introduce our high density ePTFE film product.
