Ekonol Filled PTFE — Material Specifications, Engineering Data & OEM Supply
Engineered by HEMSUN ENGG. INDUSTRIES, Ekonol Filled PTFE is designed for demanding valve, pump, and mechanical sealing duties. Built from high-purity PTFE fluoropolymer to withstand temperatures from -200°C to +260°C with zero chemical degradation in harsh media.
Where Ekonol Filled PTFE is used
Supplied as compressor rings and oxygen-service seals where no metallic filler is permitted.
Ekonol filling is chosen for oxygen and compressor service, keeping wear low without metallic filler in the compound.
Chosen over MoS₂ and bronze grades specifically where no metallic filler is permitted — oxygen service and compressor duty are the usual reasons.

Manufacturing process
Fabrication of Ekonol Filled PTFE relies on high-tonnage powder compaction and free sintering of PTFE fluoropolymer. Preforms are pressed under strict pressure dwell parameters, then heat-treated above 342°C in forced-convection ovens to bond resin granules into a void-free, chemically resilient matrix.
Material selection notes
Physical performance of Ekonol Filled PTFE is governed by high-grade PTFE fluoropolymer polymer formulation. Outstanding chemical resistance, high elongation (up to 400%), and low surface energy make it ideal for aggressive chemical pumps, valve seating, and pharmaceutical sanitary process lines.
How to specify your order
Procurement checklist for Ekonol Filled PTFE: Specify outer dimensions (OD/ID/Length), chemical exposure media, temperature limits, and target delivery schedule. We assist in selecting the optimal virgin or filled material grade and provide itemized pricing with lead times.
Quality checks and inspection
Our quality department inspects Ekonol Filled PTFE using precision coordinate measuring machines, digital surface roughness testers, and resin specific gravity balances, ensuring 100% adherence to customer drawing nominals.
Ordering and export documentation
Domestic Ekonol Filled PTFE 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. Air and sea freight packing with desiccant and shock protection for international buyers Contact info@hemsun.com or sales@hemsun.com with your PTFE components specification.
Export packing and lead time
Global shipments of Ekonol Filled PTFE are handled by our dedicated export logistics team. Orders are packed in heavy-duty seaworthy packaging with VCI anti-corrosion barrier wrapping and dispatched with complete IEC customs documentation.
Storage and handling
Installation best practices for Ekonol Filled PTFE: Verify housing bore chamfers (15° to 30°) prior to insertion to prevent seal shearing. Store unused inventory in original packaging in a dust-free storage area.
Compliance & Standards
HEMSUN is a DGFT IEC registered exporter (Government of India). Filler content and sintered density are verified per ASTM D792 on each batch, with tensile and elongation checked per ASTM D4894. A mill test certificate stating the lot, filler content and measured values ships with the order. Export paperwork — commercial invoice, packing list and certificate of origin — accompanies international despatch.
