PTFE Spacer — Material Specifications, Engineering Data & OEM Supply
PTFE Spacer from HEMSUN provides reliable chemical and thermal service across industrial processing plants. Manufactured in Dahegam, Gandhinagar, Gujarat, India from high-grade PTFE fluoropolymer with micro-finished sealing surfaces and full export documentation.
Where PTFE Spacer is used
Dimensional standoff maintaining a fixed gap in an assembly while chemically isolating the parts either side of it.
PTFE suits spacers because it holds a gap without corroding or bonding to the parts it separates.

Manufacturing process
HEMSUN ENGG. INDUSTRIES produces PTFE Spacer using matched punch-and-die compaction of PTFE fluoropolymer resins. Green preforms are sintered in digital PID-controlled ovens with multi-point thermocouple logging, followed by precision CNC lathe turning to achieve micron-level concentricity and smooth surface finishes.
Material selection notes
Material properties for PTFE Spacer (PTFE fluoropolymer): Total chemical inertness across pH 0–14, continuous thermal resistance from -200°C to +260°C (-328°F to +500°F), and an ultra-low dynamic coefficient of friction (0.05 to 0.10). For heavy-duty mechanical service, we offer filled formulations with glass fiber (15–25%), carbon graphite (15–33%), or bronze powder (40–60%) to resist compressive creep and abrasive wear.
How to specify your order
To evaluate PTFE Spacer for your project, submit component PDF drawings and resin requirements. HEMSUN engineers review part geometry, recommend appropriate compression tooling or CNC machining approaches, and provide competitive commercial proposals.
Quality checks and inspection
Quality verification on PTFE Spacer covers 100% critical dimension checks, dye-penetrant porosity screening, surface texture measurements, and batch traceability documentation provided with each export dispatch.
Ordering and export documentation
Domestic PTFE Spacer orders ship with GST invoice and e-way bill where applicable. Export orders include commercial invoice, packing list, and certificate of origin from our IEC-registered works. Recurring supply schedules supported with fixed drawing revision and lot numbering for plant stores Contact info@hemsun.com or sales@hemsun.com with your PTFE components specification.
Export packing and lead time
HEMSUN ENGG. INDUSTRIES manufactures PTFE Spacer in Gujarat, India, and exports directly to OEMs and industrial distributors in North America, Europe, the Middle East, Southeast Asia, and Africa. Shipments include complete mill test reports (MTR), certificates of compliance, IEC shipping bills, and export-grade protective barrier packaging inside heavy-duty cartons or seaworthy wooden boxes.
Storage and handling
Care and handling for PTFE Spacer: Protect machined sealing edges against impact during transit and staging. Do not exceed recommended compressive stress limits during mechanical flange tightening.
Compliance & Standards
HEMSUN is a DGFT IEC registered exporter (Government of India). Bore, wall and concentricity are verified on CMM against drawing nominals, with sintered density checked per ASTM D792 to confirm full compaction. A mill test certificate ships with the order. Export paperwork — commercial invoice, packing list and certificate of origin — accompanies international despatch.
