Overview

Wear-Resistant PSU is a Wear-Resistant Grade grade within PSU / PPSU (Polysulfone), widely used in industrial CNC machining due to its balanced mechanical, thermal, and machinability performance.

Wear-resistant grade with solid lubricant additives, suitable for oil-free lubricated moving parts.

Typical Applications

Wear-Resistant PSU grades are commonly used in the following fields and scenarios; our CNC machining services can provide custom parts for these industries.

Oil-free bearings
Sliding guide rails
Valve seals
Reciprocating motion parts

Key Material Advantages

Wear-Resistant PSU demonstrates the following core advantages in CNC machining and end-use applications.

Low friction coefficient
Self-lubricating
Low wear rate
Retains heat and chemical resistance

CNC Machining Guide

The following are key process points when machining PSU / PPSU (Polysulfone) material, to ensure part quality and machining efficiency.

1Material Drying

PSU is highly hygroscopic; dry at 135°C for 3–4 hours before machining to prevent silver streaks and bubbles from hydrolysis.

2Tool Selection

Use sharp carbide tools and maintain continuous cutting to avoid localized overheating at entry and exit points.

3Stress-Relief Annealing

Perform post-machining stress-relief annealing to eliminate residual stresses and prevent environmental stress cracking during use.

4Environmental Precautions

Avoid contact with ketones, esters, and halogenated hydrocarbon solvents; polishing yields a uniform high-gloss surface.
