Polymers are at the forefront in material science and have provided innovative solutions for engineering challenges. Among these, glass-filled Polytetrafluoroethylene (PTFE) represents a significant leap in the performance of coated materials. Standard PTFE is a polymer that has a broad range of temperatures and an unmatched chemical resistance. It has played a key role in many industries. The true potential of this material is only unlocked by adding glass fibers to it. This composite is known for its versatility and robustness.

Strengthened Mechanical Strength
First, the glass-filled PTFE has a remarkable mechanical strength. Glass fibers woven into PTFE create a material with greater tensile and durability.

Table 1. Comparison of Mechanical Properties


Property Standard PTFE Glass-Filled Ptfe
Tensile strength Low-cost High-quality
Compressive Strength Moderate The Superior
Rigidity Limited Enhanced


Reduced Deformation under Load
Its reduced tendency to deform when loaded is another key benefit. This “creep resistance” is critical in many applications, where the integrity and shape of materials is important.

Improved thermal conductivity
Glass fibers can also improve the thermal conductivity, which is a crucial factor in many manufacturing processes.

Glass-filled PTFE is the ultimate in durability and performance, exhibiting Good electrical properties. It also retains its Potential for Food Grade.

Industrial Applications and Uses
Glass-filled PTFE has a wide range of practical applications. It is ideal for seals, gaskets and bearings. It also excels as an insulator. Glass-filled PTFE has enhanced properties that make it ideal for high-performance components.

Glass-filled PTFE is a new standard in high-performance polymers. It enhances the capabilities of PTFE standard to meet more demanding engineering needs.

Frequently Asked Questions

Of course, we can customize pfe products to your satisfaction according to your material, size and process

The maximum size of ptfe molded plate can reach 2000mm long * 2000mm wide * 390mm thick,
ptfe rods have a maximum length of 4000mm and a diameter of 500mm

PTFE is essentially chemically inert and is highly resistant to chemical attack up to its 500º F. maximum continuous operating temperature. As indicated in the referenced PTFE Handbook above, there are a few exceptions including molten alkali metals, turbulent liquid, or gaseous fluorine; and a few fluorochemicals, such as chlorine trifluoride, ClF3, or oxygen difluoride, OF2, which readily liberate free fluorine at elevated temperatures.  Several tables are available on the web supporting appropriate usage of PTFE with chemicals and various concentrations and temperatures. 

We have a set of strict quality testing system, never expected finished products, will be tested and registered, traceable
