Working with PPSU-GF30 GF30-PTFE
Is PPSU-GF30 easy to machine?
Machines cleanly with sharp polycrystalline-diamond or carbide tooling, high speed and light feeds; glass is abrasive so expect fast edge wear, and avoid sharp internal corners because the filled resin is notch-sensitive — anneal near 190 °C to relieve stress before tight-tolerance finishing.
Can PPSU-GF30 be welded?
Ultrasonic, hot-plate and IR welding work but joint strength is limited by the fiber-poor weld line; solvent bonding uses chlorinated/aprotic solvents which can also stress-crack the part, so mechanical fastening or overmolded inserts are usually preferred.
Can PPSU-GF30 be formed, bent or molded?
Injection mold at 350–390 °C melt with 135–165 °C tools, dry to <0.02 % moisture (3–4 h at 150 °C), use generous gates and hardened wear-resistant mold steels; shrinkage is low (0.2–0.45 %) and anisotropic, so anticipate warp in thin ribbed sections.
What surface finishes work on PPSU-GF30?
Accepts pad printing, laser marking and adhesive bonding after plasma or abrasive activation; the fiber-textured surface cannot be polished to optical quality and no plating or anodizing is applicable.

PPSU-GF30 GF30-PTFE — frequently asked
What is PPSU-GF30 GF30-PTFE used for?
PPSU-GF30 GF30-PTFE is typically used for surgical instrument handles, reusable medical trays, plumbing and fluid handling fittings and high-impact structural components. In short: toughest filled sulfone; repeated steam sterilization; hydrolysis-resistant structural grade.
What is the tensile strength of PPSU-GF30 GF30-PTFE?
PPSU-GF30 GF30-PTFE has a typical tensile strength of 100 MPa (14.5 ksi) — stronger than 89% of polymer grades. Strength varies by condition: see the 5 listed tempers.
Is PPSU-GF30 GF30-PTFE easy to machine?
Reasonably — machinability is rated good (62/100, better than 60% of polymer grades). Machines cleanly with sharp polycrystalline-diamond or carbide tooling, high speed and light feeds; glass is abrasive so expect fast edge wear, and avoid sharp internal corners because the filled resin is notch-sensitive — anneal near 190 °C to relieve stress before tight-tolerance finishing.
Can PPSU-GF30 GF30-PTFE be welded?
Not readily — weldability is rated not recommended (5/100). Ultrasonic, hot-plate and IR welding work but joint strength is limited by the fiber-poor weld line; solvent bonding uses chlorinated/aprotic solvents which can also stress-crack the part, so mechanical fastening or overmolded inserts are usually preferred.

What is the maximum service temperature of PPSU-GF30 GF30-PTFE?
PPSU-GF30 GF30-PTFE is rated for continuous use to about 175°C (347 °F), and briefly to 210°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
