AFLAS rubber passes GB 4806.11-2023 food contact testing

A food grade mechanical seal is only as good as the rubber inside it. This report closes that gap: the AFLAS rubber we use tested to GB 4806.11-2023, conclusion Pass.

Five pages, issued 26 October by NTEK in Dongguan, against China's national food safety standard for food contact rubber. Sample received 19 October, tested through 26 October, signed and sealed. Material named on the report: tetrafluoroethylene-propylene rubber, AFLAS, beige.

The numbers are the part worth reading. Overall migration under 3.0 mg/dm² against a limit of 10. Permanganate consumption 2.7 mg/kg against 10. Heavy metal as lead under 1 mg/kg against 1. Sensory and soaking liquid: pass. Every line on that table says pass.

On food and beverage duty a seal is judged by what it gives off into the product, not by how it looks, and that is what this standard measures. Lepu builds Food and Beverage Mechanical Seals and food grade mechanical seal assemblies in Guangzhou: cartridge type mechanical seals, O Ring Mechanical Seals, a mechanical seal for centrifugal pump, mechanical pump shaft seals and mechanical seals for rotating equipment, plus OEM replacement mechanical seals and mechanical seal replacement parts. Send the duty and the cleaning regime, and ask for report DGF261019068HE.
