MATERIAL INTRODUCTION

01    Due to its excellent low friction, corrosion resistant, and thermal stability, PTFE is widely used in friction parts and obturators;Especially it can be used in corrosive mediums, and no other metallic or nonmetallic material can. It even have higher load capacity, thermo mechanical stability, wear resistance, and PV limit value after been modified by filling with various methods or became a plastics alloy through synthesis with some aromatic resins.

02    As a professional factory processing PTFE, we are engaged in the research about its modification and process. We have plates,bars, tubes, soft tapes, and components like bushings, seal parts,gaskets, and ball sockets and so on. To meet the guide bearing requirements of pneumatic/hydraulic cylinders under working condition of difficult lubrication, oil-free lubrication, and high lateral pressure, we also have developed several kinds of FPG guide tapes of different formulas, which have been applied in the pneumatic/hydraulic cylinders' guide ring and support ring on compressors, cranes, loaders and other various construction machines.

MATERIAL PROPERTIES 

01    With high structure strength, it can endure high lateral and reversed stresses, so can guarantee the piston or piston rod's smooth running, when is used as the pneumatic/hydraulic cylinder's guide seal.

02    With excellent wear resistance, the pneumatic/hydraulic cylinders equipped with the material will show outstanding wear-resistant , antifriction , and adhesive resistant performance under dry friction,boundary lubrication , and in liquid medium of less lubricity.

03    With excellent wear resistance, the pneumatic/hydraulic cylinders equipped with the material will show outstanding wear-resistant , antifriction , and adhesive resistant performance under dry friction,boundary lubrication , and in liquid medium of less lubricity.

04    With excellent wear resistance, the pneumatic/hydraulic cylinders equipped with the material will show outstanding wear-resistant , antifriction , and adhesive resistant performance under dry friction,boundary lubrication , and in liquid medium of less lubricity.

05    With excellent wear resistance, the pneumatic/hydraulic cylinders equipped with the material will show outstanding wear-resistant , antifriction , and adhesive resistant performance under dry friction,boundary lubrication , and in liquid medium of less lubricity.

PRODUCT ASSEMBLY

As a kind of soft tape used in pistons or piston rods' guidance seal, it can guarantee the balance movement of pistons or piston rods under lateral pressure, avoid direct contact and abrasion between metallic pistons/piston rods and cylinder body. For its work ask the tape bring no creep deformation under pressure to keep good guiding and supporting performance, the structural design between the tape and the cylinder, between the tape and the piston/piston rod are of much importance.
The typical structural design is shown in Table 1 and Table 2.
Generally, use those flat guide tapes who have “Rectangle” geometrical shape, and their thickness shall equal to the 0.05mm negative tolerance of summation of the gap length between pistons/piston rods groove depth, as h=H mm. And the guide tape's width shall equal to groove depth-0.1mm. We recommend 45°or 60° bevel lap joints to connect the tapes.
