Fluoroplast-4 and fluoroplast-4A rods made by ram extrusion

Rods are made of heat-treated granular PTFE of «О», «PN» grades (GOST 10007–80) and of fluoroplast-4A (TU 6–05–1999–85) by ram extrusion.

Rods are intended for fabrication of electrotechnical, anticorrosive and antifriction purpose parts by mechanical operation.

Warranty period of storage is 15 years from the date of production.

Quality rating of PTFE extruded rods:

Properties
Standard value
Density (specific gravity), g/сm3
2.13 – 2.19
Tensile strength, min, MPa (psi)
20 (2900)
Elongation at break, min, %
200
Hardness, Shore D, more than
54

Rods quality conforms to ISO Standard 13000-1 (grades 1 and 2). Rods also meet the physical-mechanical requirements specified in ASTM D 1710 (Type 1).

Virgin PTFE extruded rods can be produced both in metric (mm) and imperial (inches) sizes.

This year we also plan to start manufacturing filled PTFE extruded rods. Available fillers are glass fiber, carbon (coke), graphite, carbon fiber, molybdenum disulfide, bronze, and cobalt blue.
