In the injection molding process of anti-static PEEK materials, it is extremely important to effectively control the surface resistance value of the products. After the production of the anti-static PEEK particles of PRES is completed, the surface resistance of the particles is tested using a resist

PEEK vs PTFE: Which Plastic Fits Your Part?PEEK and PTFE both serve at 260°C, both shrug off most chemicals, and both sit in the high performance tier — yet they solve opposite problems. PTFE is the slipperiest solid polymer we know; PEEK is the strongest machinable plastic at high temperature.

Bearing-grade PEEK is generally the better starting point for continuous dry-sliding applications where low friction and wear resistance are the primary requirements. CF30 PEEK is often preferred when structural stiffness, dimensional stability, and load-bearing capability matter more. Neither grade is universally better for wear: tribological performance depends on PV, temperature, counter-face material, surface finish, lubrication, and the specific formulation. Under the published test data discussed below, the friction coefficient of CF30 PEEK climbs from ~0.26 to ~0.66 (+154%) as PV rises from 5 to 15 MPa·m/s — while a bearing-grade formulation falls from ~0.42 to ~0.34 (-19%).

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
