# Bearing Grade vs CF30 PEEK: Wear Resistance Compared **Meta title:** PEEK Bearing Grade vs CF30: PV Limits & Wear Data | PRES **Meta description:** At 2 m/s / 7.5 MPa, unfilled-carbon PEEK's friction coefficient climbs to ~0.66 while bearing grades fall to ~0.34. Compare wear rate, PV limits and

What Are Heat-Resistant Plastics? 6 Reliable High-Performance Engineering PlasticsUntill 2026, the common plastics with good heat-resistant properties include Polyetheretherketone (PEEK), Polyimide (PI), Polyphenylene Sulfide (PPS), Polyetherimide (PEI), Polyphenylsulfone (PPSU), and Polysulfone (PS

PEEK is inherently an excellent insulator with a volume resistivity of 1016. Glass fiber reinforced PEEK maintains this full insulation. Carbon fiber reinforced PEEK, however, becomes electrically conductive. Electrostatic dissipation is only achieved in specially engineered antistatic PEEK grades w

PEEK PEEK is engineered for continuous service down to -60°C, and Victrex Pipes PEEK polymer tubing has been proven at even lower temperatures: no break in crush test at -60°C (-76°F), and reliable impact resistance demonstrated at -70°C (-94°F). This makes PEEK one of the few high-performance ther

Why PEEK Operates at 260°C with a Glass Transition Temperature of Only 143°CA persistent question in high-performance polymer selection is this: PEEK (Polyetheretherketone) has a glass transition temperature (Tg) of just 143°C, yet its rated continuous service temperature is 260°C—

This article explores the strongest filaments for 3D printing, including PEEK, polycarbonate, carbon fiber reinforced nylon, nylon, TPU, and Ultem. Each filament's properties, applications, and considerations for use are discussed, providing insights for selecting the right material for various projects. Understanding these options is crucial for achieving durable and high-quality 3D prints.

PEEK Sheet Thermal Stability & Annealing – HDT, Conductivity & FlatnessPEEK sheet (polyetheretherketone plate) delivers continuous 260°C service and 343°C melt, with post-extrusion annealing at 200–250°C required to lock ≥98% flatness and isotropic thermal conductivity before CNC milling. Below is t

To prevent PPSU sheet warpage during CNC milling, run a 3-cycle annealing process: pre-anneal the blank at 140–160°C for 2 hours and furnace-cool below 60°C; rough both faces alternately leaving 0.3–0.5mm allowance, then re-anneal; finish with sharp uncoated carbide at low feed using compressed-air

PEEK Rod Mechanical Properties & Wear Resistance: Technical ReferenceDirect Answer: PEEK rods deliver tensile strength from 100 MPa (Unfilled) up to 265 MPa (CF30), flexural modulus from 4.0 GPa to 21+ GPa, and compressive strength up to 320 MPa. Unfilled PEEK offers the best toughness and 20-50% el

PEEK Rods Selection Guide: Unfilled vs GF30 vs CF30 vs ESDChoosing the correct PEEK rod grade is rarely a matter of picking "the strongest" or "the cheapest" option, but rather a disciplined engineering decision in which mechanical load, continuous service temperature, chemical environment, electric
