Food Grade PTFE Ball — Material Specifications, Engineering Data & OEM Supply
Engineered by HEMSUN ENGG. INDUSTRIES, Food Grade PTFE Ball 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 Food Grade PTFE Ball is used
Sealing and flow-control element in ball valves and pump check seats, where sphericity and surface finish decide shutoff tightness and operating torque.
Specified where FDA 21 CFR 177.1550 listed resin is required for direct food, dairy and beverage contact, with cleanability and no taste transfer.
Common in dairy, brewing, edible-oil and bottling lines, and on filling equipment that is washed down between batches.
Supplied to drawing across the published range — FDA 21 CFR compliant — food, dairy, pharma and beverage safe; Material: 100% Virgin PTFE — no fillers, no additives, no extractables — with dimensional and material reports on request.

Manufacturing process
Food Grade PTFE Ball is manufactured at our Dahegam facility using high-pressure compression moulding followed by computer-controlled oven sintering up to 370°C and precision CNC finishing. Raw PTFE fluoropolymer resin is cold-pressed at 300 to 450 kg/cm² (3,000 to 4,500 psi) into rigid green preforms. Sintering under programmed heating ramps enables complete particle coalescence, eliminating internal porosity and yielding high tensile and dielectric strength.
Material selection notes
The chemical resilience of PTFE fluoropolymer ensures Food Grade PTFE Ball remains completely impervious to corrosive chemicals, steam, and industrial fuels. Its low frictional properties reduce torque requirements in valve assemblies and prevent galling against mating metal faces.
How to specify your order
Sizing and ordering Food Grade PTFE Ball: Share drawing files (STEP/PDF), annual volume projections, and any compliance requirements (FDA, USP Class VI). Our technical department confirms tooling costs, sample schedules, and volume production lead times.
Quality checks and inspection
Every batch of Food Grade PTFE Ball undergoes stringent quality checks at our Dahegam plant: laser micrometer diameter scanning, surface roughness profilometry (Ra ≤ 0.2 µm), and tensile/elongation testing per ASTM D4894 to ensure complete material coalescence.
Ordering and export documentation
Domestic Food Grade PTFE Ball 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 balls specification.
Export packing and lead time
HEMSUN ENGG. INDUSTRIES supplies Food Grade PTFE Ball to international valve and pump manufacturers globally. Export orders include comprehensive quality certificates, packing lists, and seaworthy timber boxing compliant with ISPM 15 standards.
Storage and handling
Installation best practices for Food Grade PTFE Ball: 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). Moulded from FDA 21 CFR 177.1550 listed resin; the material certificate traces the resin lot behind each batch, and sintered density is checked per ASTM D792. Export paperwork — commercial invoice, packing list and certificate of origin — accompanies international despatch.
Frequently Asked Questions
What makes your PTFE Ball food grade?
Our Food Grade PTFE Balls are manufactured from 100% virgin PTFE resin compliant with FDA 21 CFR — no fillers, no plasticizers, no heavy metals, no extractables. Non-toxic, odorless, tasteless, and CIP/SIP sterilizable. Safe for direct contact with food, beverages, dairy, and pharmaceutical products.
What is the largest Food Grade PTFE Ball you manufacture?
We manufacture Food Grade PTFE Balls up to 310mm diameter — one of the largest food-grade plastic balls available globally. Most suppliers stop at 100mm. Our 310mm Food Grade PTFE Ball serves large-bore food processing valves and pharmaceutical reactor valves requiring FDA compliance.
Are Food Grade PTFE Balls suitable for steam sterilization?
Yes. Food Grade PTFE Balls are fully CIP and SIP compatible — they withstand steam sterilization and all standard food and pharmaceutical cleaning and sanitizing agents without degradation or dimensional change.
Do you export Food Grade PTFE Balls to Germany and USA?
Yes. We regularly export FDA-compliant Food Grade PTFE Balls to Germany, USA, Japan, UAE, Singapore, and Brazil for food equipment, dairy, beverage, and pharmaceutical valve and pump applications.
