Manufacturing process
Production of Stainless Steel Filled PTFE combines cold isostatic/uniaxial compaction of PTFE fluoropolymer powder with multi-stage thermal free-sintering. Compaction loads are held under precise electronic dwell timing to bleed out microscopic air pockets. Sintered blanks are then transferred to climate-controlled CNC turning and milling centers to machine critical drawing features.
Material selection notes
Manufactured from PTFE fluoropolymer, this component combines high tensile strength (20–35 MPa) with excellent chemical and weathering resistance. The material maintains flexibility at low temperatures while providing stable compressive support under high system pressures.

Ordering and export documentation
Domestic Stainless Steel 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. Material certificates and dimensional reports attached for qualified pharmaceutical and OEM shipments Contact info@hemsun.com or sales@hemsun.com with your PTFE components specification.
Export packing and lead time
International distribution of Stainless Steel Filled PTFE is supported with multi-currency commercial terms, export shipping documentation, and protective multi-layer packaging to ensure components arrive in pristine condition worldwide.
Storage and handling
Maintenance and care for Stainless Steel Filled PTFE: Clean components using neutral solvent degreasers or warm water solutions. Avoid metal scrapers or abrasive pads that could abrade the precision-machined sealing surfaces.
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.
