Kettle Seals
Food-zone kettle and jug seals in boil-proof, taste-free LFGB silicone.
Application Overview
A kettle seal touches boiling water all day — taste transfer or volatile release ends up in the tea. We produce kettle, jug and coffee-machine seals in platinum-cured LFGB silicone validated for repeated boiling, with anti-scale geometry options and spout gaskets molded flashless for clean water paths.
Technical Standards
- ✓LFGB tested; repeated-boiling (200+ cycle) stability verified
- ✓FDA 21 CFR 177.2600 and EU 1935/2004 compliance
- ✓Taste / odor sensory screening per material batch
- ✓BfR XV recommendation for silicone elastomers
Manufacturing Process
Seals are LSR injection molded flashless for water-path cleanliness; flat gaskets can be die-cut from calibrated sheet.
- Platinum-cure compounds for taste neutrality
- Anti-scale lip geometry options reduce limescale buildup
- Post-cure bakes out volatiles before food contact
- One-piece spout-to-body gaskets avoid assembly seams
Quality Inspection
- 🔍100% visual inspection (flash, short-shot, contamination) before packing
