FOAM-IN-PLACE MATERIAL
1K PVC compound for oven-cured metal lid gaskets
One-component PVC is supplied as a premixed plastisol for controlled dispensing into a metal lid groove. After the continuous bead is formed, the lid passes through a validated oven profile to create the final cellular gasket.
Bead quality depends on material temperature, dispensing output, path speed, start-stop overlap and the metal-cap temperature reached in the oven. Compound, machine and curing settings must be approved as one production process.

Approval before production
The values above are selection references, not a release specification. Final dimensions and performance must be confirmed with the actual lid, closing process and filled medium.
