Huahao Sealing · Carbon Graphite Components
Huahao Sealing provides FDA food-grade resin-impregnated carbon graphite seals for the food and pharmaceutical industry. Completely oil-free self-lubricating operation with zero metal-ion leaching and grease contamination risk, compliant with FDA and EU food contact material standards and HACCP requirements, suited for mixers, fillers, transfer pumps and CIP equipment.
Food mixer copper bushing wear produces copper ion contamination, violating FDA and EU food contact material standards
Grease is flung off during mixing and mixes into food products, causing batch rejection and consumer complaints
Pharmaceutical CIP cleaning uses acid/alkali (pH 2-12); seals suffer chemical corrosion and failure
Clean production environments require zero metal particle shedding; metallic bearing wear particles fatally contaminate product
FDA food-grade resin-impregnated carbon graphite (M106K), completely oil-free self-lubrication with zero grease contamination risk
Carbon graphite is non-metallic with zero copper or iron ion leaching, compliant with FDA 21 CFR 178 food contact material standards
Chemically inert against CIP acid/alkali cleaning fluids (pH 2-12), tolerates steam sterilization and acid-alkali alternating cleaning
Carbon graphite wear produces trace black carbon powder that is easily detected and removed, with no hidden metal contamination risk
| Temperature | -20°C ~ 220°C |
| Pressure | ≤ 10 MPa |
| Speed | ≤ 10 m/s |
| Media | Food slurries, CIP fluids, steam |
| Grade | M106K (FDA Resin) |

Yes. M106K food-grade resin-impregnated carbon graphite is certified to FDA 21 CFR 178 food contact material standards, completely oil-free with zero metal-ion leaching, suited for HACCP food safety management systems.
Replace copper bushings with M106K food-grade carbon graphite bushings. Carbon graphite is non-metallic with zero copper ion leaching; self-lubricating without grease, no oil flung into product. Completely resolves dual copper-ion and grease contamination.
No. Carbon graphite is chemically inert across pH 0-14, tolerating CIP acid/alkali (pH 2-12) and steam sterilization. Resin-impregnated grades fill porosity, further reducing permeation and chemical attack risk.
Carbon graphite wear produces trace black carbon powder with high contrast against food color, easily detected and removed. Carbon powder is itself food-grade (FDA certified), harmless in trace amounts. Compared to metallic wear particles, carbon powder contamination is easier to control and detect.
