Bronze Filled PTFE Manufacturer

Applications

Where Bronze Filled PTFE is used

Supplied as hydraulic guide rings, wear bands and heavily loaded bushes, usually at 40% or 60% fill.

Bronze filling gives the highest load capacity and thermal conductivity of the common PTFE compounds, suited to hydraulic and high-PV duty — not for chemically aggressive media.

Process

Manufacturing process

Our dedicated manufacturing cells produce Bronze Filled PTFE from premium PTFE fluoropolymer powder stock. After uniaxial preforming in precision tooling, components undergo computer-monitored sintering cycles and diamond-tooled CNC profiling to hold exact drawing dimensions.

Material

Material selection notes

Featuring FDA-compliant virgin PTFE fluoropolymer or specialized filled compounds, Bronze Filled PTFE provides reliable sealing and low-friction motion under continuous operating temperatures up to +260°C. Filler additions enhance mechanical rigidity, wear resistance, and thermal conductivity for heavy mechanical loads.

Selection

How to specify your order

To evaluate Bronze Filled PTFE 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

Quality checks and inspection

Quality assurance for Bronze Filled PTFE includes 100% optical dimensional inspection, digital micrometer verification, CMM coordinate layout testing, and water displacement specific gravity checks according to ASTM D792. High-voltage spark testing up to 80 kV/mm verifies absence of internal pinholes and voids.

Supply

Ordering and export documentation

Domestic Bronze 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. 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

Export packing and lead time

Export customers receive complete logistics assistance for Bronze Filled PTFE, including FOB/CIF shipping quotes, express air courier delivery for prototype samples, and secure sea-freight container packing with full batch traceability.

Care

Storage and handling

Storage and operating notes for Bronze Filled PTFE: Keep parts in sealed packaging at ambient room temperature. During equipment overhaul, inspect sealing lips for particulate embedding and replace components showing mechanical wear.

Compliance

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.
