HEMSUN ENGG. INDUSTRIES manufactures PTFE balls in India and exports to Qatar, shipping to Hamad Port for the Mesaieed and Ras Laffan industrial cities. We supply solid PTFE spheres from 5 mm to 310 mm in virgin and filled grades for LNG, petrochemical, desalination and industrial applications.
Why buyers in Qatar source PTFE balls from HEMSUN
Qatar’s industrial demand is dominated by LNG production at Ras Laffan and petrochemicals at Mesaieed, both operating at very large scale with correspondingly strict specifications. Cryogenic service is a distinctive requirement here: PTFE retains useful mechanical properties down to around -200°C, which is one of the few polymers that remains serviceable at LNG temperatures where elastomers become brittle. Desalination adds continuous chemical dosing demand, and the country’s construction and utilities sector contributes water treatment consumption.
Industrial clusters
- Ras Laffan Industrial City
- Mesaieed Industrial Area
- Hamad Port industrial zone
- Doha industrial area
- Umm Bab and Dukhan

Quality Assurance, Testing Protocols & Traceability
- Dimensional CMM Profilometry: Critical diameters, concentricity, and sphericity are verified on coordinate measuring machines against drawing nominals.
- Dielectric Breakdown Voltage Testing: High-voltage spark testing screens moulded parts for micro-voids, pinholes, and internal conductive inclusions before dispatch.
- Specific Gravity & Density Verification: Water displacement density checks according to ASTM D792 ensure full preform compaction and complete oven gel sintering.
- Certificate of Compliance & MTR: Every dispatch includes mill test certificates confirming raw resin lot traceability, filler content, and tensile/elongation values.
Installation, Machining & Maintenance Recommendations
- Tooling Geometry for Machining: Use polished tungsten carbide (C2 grade) or polycrystalline diamond (PCD) inserts with high positive top rake angles (15° to 25°) and sharp cutting edges to prevent material smearing.
- Feed & Speed Rates: High spindle speeds (200 to 450 m/min) combined with moderate feed rates (0.05 to 0.15 mm/rev) ensure mirror surface finishes without localized frictional heating.
- Coolant Application: Water-soluble synthetic coolants or clean air blast prevent thermal expansion during high-speed CNC turning and milling passes.
