POK, and only POK
From authorization to production
Authorized distributor of Hyosung POKETONE for China, with our own compounding plant. 15 native grades, 67 modified grades — one technical team from grade selection and mould trials through to volume supply.
The engineering plastic
made from carbon monoxide
POKETONE is a highly crystalline aliphatic polyketone (POK) made by alternating copolymerisation of carbon monoxide and olefins. Its backbone is built entirely of carbon, and the regularly spaced carbonyl groups (C=O) give it a tight crystalline structure — which is why it delivers high toughness, high wear resistance, chemical resistance, hydrolysis resistance and outstanding gas barrier at the same time.
There are two families: the binary alternating copolymer of carbon monoxide and ethylene, used for high-strength fibre; and the terpolymer made by adding propylene, which is the workhorse of engineering-grade POK.
Three product lines, from resin to semi-finished stock
Native resin for batch consistency, modified grades for specific duty, sheet and rod for small-batch machining and prototype validation.
General Injection Moulding
M330A is the reference grade; M130F is the highest-flow food-contact grade, for thin walls, long flow paths and precision small parts.
High Impact
M630A is the classic high-impact grade, the M730 series goes higher on impact, and M710F is an ultra-low-flow grade for extrusion.
Food Contact
The F suffix denotes food-contact grades; declarations of compliance and migration test reports are supplied with them.
Specialty Grades
M640A suits high-temperature service; M630V is for long-term outdoor exposure.
Glass Fibre Reinforced
G3 / G6 / G8 / G10 correspond to 15% / 30% / 40% / 50% glass fibre loading.
Carbon Fibre Reinforced
C2 / C6 carry 10% / 30% carbon fibre; CFST is a high-flow carbon-fibre toughened system.
82 grades available, including glass fibre 10–50%, carbon fibre 10–30%, PTFE / silicone / MoS₂ wear packages and V0 flame-retardant systems.

Field notes on selection and processing
Notes from cases we have run: which grade for which condition, how to set the process window, how to trace a failure back. Not material primers — decision inputs you can use.
