With nylon as an additive, PCTPE filaments are flexible, slippery, and wear resistant. They’re good for making sturdy components that move and rub against other objects. Since they're UL rated 94 HB and 94 V-2, they prevent the spread of flames both horizontally and vertically.

Print these filaments on a fused filament fabrication (FFF) 3D printer. Because they’re flexible, they require a slow feed rate so they don’t jam. Store them in a sealed container with a desiccant, or use a dehumidifying cabinet, since moisture in the air can degrade their printing quality.

Tensile strength is the best measure of a filament's overall strength. Similar to the stress applied on a rope during a game of tug-of-war, it's the amount of pulling force a material can handle before breaking. A higher rating means a stronger filament. A tensile strength of 5,000 psi and above is considered good; 12,000 psi and above is excellent.

Maximum exposure temperature is the point at which a printed part will begin to deform. Above this temperature, your printed parts will start to lose structural integrity.
