Engineering plastics, explained in a minute

Seven short walkthroughs from our Dongguan plant: what each material holds in stock, the grades and colours available, the numbers that decide the choice, and where it usually ends up on a line.

PEEK 60 seconds

PEEK sheet and rod — what we hold in stock

Continuous service to 270 °C with 300 °C peaks, in natural, black and anti-static grades. Watch how the ESD reading holds 10⁶–10⁸ Ω in any humidity.

PEEK is the champion of high-temperature resistance. Instantaneous temperature can reach 300 °C and continuous operation 270 °C. Our PEEK categories are natural PEEK sheet, black PEEK sheet and ESD PEEK sheet — we are a leading brand of anti-static material in China, and the anti-static value is stable at 10⁶ to 10⁸ Ω in any location and any weather condition. PEEK is mainly used in semiconductors, mechanical parts and medical apparatus. It is mechanically very strong, with a Rockwell hardness around R120 to R130, and has better rigidity and wear resistance.

POM 54 seconds

POM (acetal) — six grades, from white to conductive

The grade list machinists ask about first: white, black, beige, black ESD, ESD and conductive — with the strength and rigidity that make acetal the default for gears.

Read the transcript

POM, polyoxymethylene, is a high-strength thermoplastic engineering plastic, renowned for its high strength and rigidity — known in the trade as acetal steel. Our POM categories are white POM sheet and rod, black POM sheet and rod, ESD POM sheet and rod, beige POM sheet and rod, black ESD POM sheet and rod, and black conductive POM sheet and rod. It is widely used in electronics, electrical appliances, fixtures, gears, sliding and rotating machinery, medical treatment and sports equipment.

PPS 53 seconds

PPS — 220 °C continuous, 40% glass filled available

Chemical and corrosion resistance with excellent electrical insulation, plus a glass-fibre grade strong enough to replace metal gears.

Read the transcript

PPS, polyphenylene sulfide, can work continuously at 220 °C. It has strong corrosion resistance and chemical resistance, and excellent electrical insulation. PPS board categories mainly include natural PPS sheet, black PPS sheet and PPS with 40% glass fibre — the enhanced mechanical strength can completely replace metal gears. PPS is mainly used in auto parts, electronic and electrical components, chemical equipment and other fields.

PEI 27 seconds

PEI (ULTEM) — strength, insulation and flame resistance

Dimensional stability that holds through temperature and humidity swings, with inherent flame resistance — which is why aerospace and medical work specify it.

Read the transcript

PEI, polyetherimide: high strength and rigidity, good wear resistance and good dimensional stability, with excellent electrical properties. It is not easy to burn, and holds its properties under different temperature and humidity conditions. It is widely used in electronic appliances, aerospace, medical apparatus and other demanding industries.

PA 39 seconds

PA66 and cast nylon — strength, friction, thermal conductivity

Nylon as an engineering plastic: high mechanical strength, low friction and good heat conduction, in black, glass-filled and PA66 grades.

Read the transcript

PA, polyamide, commonly known as nylon, is a polymer engineering plastic possessing high mechanical strength, excellent friction behaviour and good thermal conductivity. It is widely used in automotive parts, electronic and electrical equipment, construction machinery and other fields. Our PA category includes black PA sheet and rod, glass-fibre reinforced PA and PA66.
