Product Overview
PEEK (Polyetheretherketone) balls are premium, high-performance engineering plastic spheres designed for extreme environments. PEEK exhibits outstanding mechanical strength, rigidity, and resistance to creep, combined with a continuous operating temperature limit of +250°C (and short-term exposure up to +300°C). Designed as polyetheretherketone check spheres and HPLC pump check balls, PEEK balls maintain their mechanical properties at extreme temperatures and pressures, and are highly resistant to aggressive chemicals, steam, hot water, and subsea oil extraction pressures. Sourcing PEEK balls from Hemsun Engg. Industries gives B2B clients access to direct manufacturing, custom sizing, and material quality assurance directly from our Gujarat factory.
Key Technical Features of PEEK

PEEK Extrusion & High Precision Grinding Process
Resin Selection: Premium, unreinforced polyetheretherketone (PEEK) resins are sourced to ensure structural integrity.
Extrusion Molding: PEEK resin is extruded into dense rods under high temperatures, maintaining material purity.
Thermal Annealing: Extruded PEEK rods undergo annealing to relieve internal stresses, ensuring dimensional stability.
Precision Grinding: CNC lathes machine the blanks, and centerless grinders achieve spherical roundness and surface quality.
Quality Audit: Spheres are checked for roundness and diameter using digital micrometers and roundness gauges.
Typical PEEK Ball Applications
PEEK balls are chosen for high pressure, high temperature, and aggressive chemical environments:
Liquid Chromatography (HPLC)
Biocompatible check balls in high-pressure chromatography pumps handling aggressive solvents.
Oil & Gas Check Valves
Used in downhole drilling equipment and subsea valves exposed to high temperatures, pressures, and corrosive gases.
Aerospace Actuators
Lightweight spheres in aircraft control valves requiring reliable high-temperature performance.
Autoclave Sealing Component
Acts as sealing elements in industrial steam sterilization systems, resisting hydrolysis.
Chemical Dosing Pumps
Reciprocating check balls in high-wear chemical injection systems.
Semiconductor Processing
High purity spheres in wafer handling equipment, resisting chemical clean cycles.

PEEK Balls FAQ
What makes PEEK better than other engineering plastics?
PEEK offers a unique combination of high mechanical strength, creep resistance, high-temperature resistance (+250°C), and chemical inertness.
What is the maximum operating temperature of PEEK balls?
PEEK balls can operate continuously at temperatures up to +250°C, and can withstand short-term exposure up to +300°C.
Are PEEK balls food safe and biocompatible?
Yes. Unreinforced PEEK is inherently food safe, biocompatible, and USP Class VI compliant, making it standard in chromatography and medical devices.
Is PEEK resistant to acids and bases?
Yes. PEEK has excellent chemical resistance to a wide range of organic solvents, acids, and bases, although it is soluble in concentrated sulfuric acid.
Do PEEK balls absorb water?
PEEK has very low moisture absorption (less than 0.1% at saturation), making it extremely stable in steam and water applications.
Why are PEEK balls more expensive than PTFE?
PEEK resin is a premium specialty polymer with high raw material cost, and it requires high temperatures and specialized equipment to extrude and grind.
