Food Industry PTFE — Material Specifications, Engineering Data & OEM & ODM Supply
Custom-engineered by HEMSUN ENGG. INDUSTRIES in Dahegam, Gujarat, Food Industry PTFE provides exceptional chemical and thermal resilience for food industry components. Produced from certified PTFE fluoropolymer with strict density control and diamond-tooled CNC finish machining for global industrial processors.
Where Food Industry PTFE is used
PTFE is chosen for near-universal chemical inertness, a −200°C to +260°C service band, and the lowest friction of the common engineering polymers.
Common in dairy, brewing, edible-oil and bottling lines, and on filling equipment that is washed down between batches.

Manufacturing process
Food Industry PTFE 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
Physical performance of Food Industry 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.

Export packing and lead time
Global shipments of Food Industry 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 Food Industry 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). 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
Is PTFE suitable for food and beverage equipment?
FDA-suitable PTFE grades are used for non-stick surfaces, valve components, and hygienic seals where chemical resistance and cleanability matter. Material certificates can be supplied for audit trails.
What food-industry components does HEMSUN manufacture?
Food-grade sheets, rods, gaskets, bushings, conveyor parts, and custom machined components for fillers, mixers, and packaging lines.
