Regulatory Compliance
NGM-S12B natural PEEK rod meets:
l FDA 21 CFR §177.2415 — food contact compliant
l USP Class VI — medical device biocompatibility
l ISO 10993 — biological evaluation of medical devices
l RoHS & REACH — environmental compliance
l UL94 V-0 — flame retardancy at 1.45mm
Common Industrial Applications
Semiconductor Industry
PEEK rods are machined into wafer handling components, test socket retainers, CMP ring guides, and transport cassette pins. The material’s inherent purity and low outgassing make it suitable for Class 1 cleanroom environments.
Medical Device Manufacturing
CNC-machined PEEK components include dental abutments, spinal fusion cages, orthopaedic trial spacers, and surgical instrument handles. NGM-S12B’s biocompatibility and sterilisability (autoclavable at 134°C, 1000+ cycles) are critical.
Oil & Gas
PEEK rods are turned into downhole electrical connector insulators, seal backup rings, and subsea valve seats. The material resists H2S, CO2, and amine corrosion inhibitors at elevated temperatures.
Aerospace
Machined PEEK parts replace aluminium in interior brackets, cable clamps, and ducting supports, delivering 50–60% weight savings with comparable stiffness.

Quality Assurance
Every NGM-S12B production batch includes:
l Certificate of Analysis (CoA) with actual measured properties
l Material Test Report (MTR) per ASTM standards
l Full traceability from resin lot to finished rod
l Dimensional inspection report
l RoHS/REACH compliance certificate
FAQ
Q1: What does NGM-S12B mean?
NGM-S12B is NAGOMER‘s internal grade designation for natural (unfilled) virgin PEEK rod. NGM stands for NAGOMER, S indicates sheet/stock shape, 12B is the grade code for unfilled PEEK.
Q2: Can NGM-S12B PEEK rods be sterilised?
Yes, NGM-S12B PEEK rods can withstand autoclave sterilisation at 134°C for over 1000 cycles without significant property loss. They are also compatible with gamma radiation, ethylene oxide (EtO), and dry heat sterilisation methods.
Q3: What is the maximum rod diameter available?
NAGOMER produces NGM-S12B PEEK rods up to 200mm in diameter. Larger diameters may be available as custom orders. Contact our sales team for specific requirements.
Q4: Is NGM-S12B suitable for implantable medical devices?
NGM-S12B meets USP Class VI and ISO 10993 biocompatibility standards. It is suitable for medical device components including implants, though final device certification depends on the specific application and regulatory pathway.
