TUFLAR™ is Keltrol's uniquely formulated UHMW-PE polymer having a molecular weight range of 3.5 to 6 million. The long chain of molecular structure of UHMW polyethylene can be degraded if handled improperly during the processing from resin to final product. Keltrol has the technology to assure that all TUFLAR™ products exhibit optimum properties due to our patented ram extrusion process.

MACHINING OF TUFLAR™

TUFLAR™ can be sawed, milled, planed, drilled, turned or punched on equipment generally used for wood and metals.

• Stellite and carbide tipped cutting tools are recommended because they are more economical in the long run. Wide cutting tools that have wide tooth spacing to provide good chip clearance are essential.
• The higher the cutting speed, the better the surface finish will be; however, cutting speeds are limited by frictional heat build up.
• Too much heat should be avoided when machining TUFLAR™ in order to retain dimensional stability. Cooling can be accomplished with water soluble coolants.
