PEEK Rod
PEEK is a high-performance thermoplastic that is tough, durable, firm, and creep resistant.
It offers excellent thermal, chemical, and hydrolysis resistance as well as excellent
resistance to abrasion and dynamic fatigue. Its ability to run at high continuous
temperatures up to (250º C) without permanent property degradation along with stable
electrical properties makes PEEK an excellent alternative to fluoropolymers in aggressive
environments. PEEK has also been shown to exhibit very low smoke and toxic gas emission when
exposed to flame.
PEEK rod is the most common PEEK shape that is suitable for machining, CNC, grinding and
nearly all other processing way.
JUNHUA ChinaPEEK offers the most diversed PEEK rod dimensions in the world, JUNHUA ChinaPEEK
offers PEEK rod from dia 3mm up to dia 260mm. PEEK rods are avaiable in PEEK Natural, PEEK
Black, 30% Glass fiber filled PEEK, 30% Carbon fiber filled PEEK, and bearing grade PEEK(10%
PTFE,10% Carbon fiber,10% Graphite,70% PEEK).
Main Advantages of PEEK Rod
- ● 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.
