Working with Tough 2000 Durable-PP
Is Tough 2000 easy to machine?
Drills, taps and mills cleanly with sharp tools, high speed and light feed; keep cutters cool because the part softens above ~50 °C and edges chip if the resin is under-cured.
Can Tough 2000 be welded?
Thermoset — cannot be heat welded; join with cyanoacrylate, epoxy or a bead of the same liquid resin flashed under a 405 nm lamp.
Can Tough 2000 be formed, bent or molded?
Shape is set by printing: orient parts so hinges and snap features load across layers, use 50–100 µm layers, wash 5–10 min in IPA (avoid long soaks that swell and soften) and post-cure with heat + 405 nm UV to reach datasheet strength.
What surface finishes work on Tough 2000?
Sands and wet-polishes to a smooth surface; primer + paint or vapour-free spray finishes adhere well, but plan for post-cure shrinkage (~0.2–0.5 %) and use UV-blocking topcoats since bare parts yellow and embrittle in sunlight.
Tough 2000 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

Tough 2000 Durable-PP — frequently asked
What is Tough 2000 Durable-PP used for?
Tough 2000 Durable-PP is typically used for snap-fit housings and clips, living hinges, functional assembly prototypes, press-fit and threaded test parts, handheld device enclosures and drop-test prototypes. In short: impact-resistant ABS-like resin.
What is the yield strength of Tough 2000 Durable-PP?
Tough 2000 Durable-PP has a typical yield strength of 44 MPa (6.38 ksi) and a tensile strength of 32 MPa (4.64 ksi) — weaker than 60% of polymer grades. Strength varies by condition: see the 7 listed tempers.
Is Tough 2000 Durable-PP easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Drills, taps and mills cleanly with sharp tools, high speed and light feed; keep cutters cool because the part softens above ~50 °C and edges chip if the resin is under-cured.
Can Tough 2000 Durable-PP be welded?
Not readily — weldability is rated not recommended (5/100). Thermoset — cannot be heat welded; join with cyanoacrylate, epoxy or a bead of the same liquid resin flashed under a 405 nm lamp.
What surface finishes work on Tough 2000 Durable-PP?
Sands and wet-polishes to a smooth surface; primer + paint or vapour-free spray finishes adhere well, but plan for post-cure shrinkage (~0.2–0.5 %) and use UV-blocking topcoats since bare parts yellow and embrittle in sunlight.
Can Tough 2000 Durable-PP be formed, bent or molded?

What is the maximum service temperature of Tough 2000 Durable-PP?
Tough 2000 Durable-PP is rated for continuous use to about 40°C (104 °F), and briefly to 70°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Tough 2000 ABS-like and Tough 2000 GREEN?
ABS-like is the default condition — default choice for functional prototypes and enclosures that need ABS-like stiffness plus moderate impact toughness. GREEN: reference state only — properties are far below spec until UV/thermal post-cure; never use green parts for load-bearing service. Yield strength is 44 MPa in ABS-like versus 20 MPa in GREEN.
