PEEK Filament
Polyether ether ketone, or PEEK, is one of the highest performing polymer plastics available.
This high-purity and high-temperature polymer has excellent dielectric properties, a very
low coefficient of friction, and withstands the most rigorous physical and mechanical
stresses.
JUNHUA ChinaPEEK manufactures PEEK tubing by extrusion，precision PEEK tubing are mainly used
in HPLC and medical industry, all PEEK tubing is extruded in JUNHUA's GMP standard clean
room. JUNHUA ChinaPEEK can ensure OD & ID ±0.03mm tolerance in our standard extruded tubing.
Colored PEEK tubing, color stripped PEEK tubing and special modified PEEK tubing is also
available.
Main Advantages of PEEK Filament
- ● Good wearing performance with or without load
- ● High service temperature(long term 260C
- ● Good mechanical strength
- ● Good chemical resistance & Hydrosis resistance
- ● FDA approved
PEEK Material and Types of it's Modification
PEEK5600G (unfilled PEEK or natural PEEK)
PEEK5600G is one of unfilled or natural PEEK.Outstanding chemical resistance and a high operating temperature (up to 250℃/480F) round out PEEK profile.PEEK5600G has excellent dimensional stability combined with high creep stability, ensuring the suitability of PEEK for the most sophisticated machined parts.
PEEK5600GF30 ( 30% glass fiber filled PEEK)
Compared with unfilled PEEK(PEEK5600G),this 30% glass fiber reinforced PEEK material(PEEK5600GF30) exhibits increased mechanical strength and high rigidity.Plus, improved creep strength and dimensional stability are delivered by the 30% glass fiber filled PEEK.
PEEK5600CF30 (30% carbon fiber filled PEEK)
PEEK5600CF30 is a 30% carbon filled PEEK material that is manufactured by JUNHUA PEEK. Its carbon fiber reinforcement supports the material a high level of rigidity. Carbon fiber reinforced PEEK demonstrates very high mechanical strength values.
PEEK5600LF30( HPV PEEK or bearing grade PEEK)
PEEK5600LF30 black is developed especially for bearing and sliding applications. HPV PEEK is based on a PEEK polymer that has been modified with 10% each of PTFE, graphite and carbon fibres. It combines the properties of a high-grade matrix material with special, wear-improving additives.
