Working with PET Solid Lubricant Filled (TX)
Is PET easy to machine?
Machines like a free-cutting engineering plastic: sharp positive-rake carbide, high speed, light finishing passes and air/mist cooling give excellent surface finish and tight tolerances; watch for stress relief in thick stock (anneal before finish cuts).
Can PET be welded?
No solvent bonding — join by ultrasonic, hot-plate, IR or laser welding, or use cyanoacrylate/epoxy after abrasion/plasma treatment; mechanical fastening and self-tapping screws work well.
Can PET be formed, bent or molded?
Dry pellets to <0.02 % moisture (150 °C, 4 h desiccant) to avoid hydrolytic IV loss; melt 265–295 °C with hot mold 100–145 °C for full crystallization, or chilled mold/copolyester for clear amorphous APET sheet that thermoforms readily.
What surface finishes work on PET?
Takes machining, printing, hot stamping and vacuum metallizing well after corona/flame or plasma pre-treatment; can be laser-marked, but paint adhesion needs a primer and no plating/anodizing applies.
