Frequently Asked Questions (FAQs)
What is cured silicone sheet?
Cured silicone sheet is a fully vulcanized, solid elastomer that has completed its chemical cross-linking process during manufacturing. It arrives ready for immediate fabrication, conversion, and die-cutting into finished gaskets, seals, and protective barriers.
How is cured silicone sheet converted into finished parts?
Because the elastomer is fully cured, fabricators can process ElastaPro cured silicone sheeting using standard converting methods including die-cutting, water-jet cutting, laser cutting, knife cutting, and slitting into narrow rolls.
What is the difference between cured solid silicone sheet and silicone sponge or foam?
Cured solid silicone is a fully dense elastomer with no internal voids, providing high tensile strength, superior tear resistance, and high compressive force deflection for pressure sealing.
Silicone sponge and foam contain closed-cell gas structures, offering higher compressibility, lower weight, and conformability for low-clamp-force gasketing.
Does ElastaPro supply cured silicone sheeting with adhesive backing?
Yes. ElastaPro offers cured silicone sheet with factory-applied pressure-sensitive adhesive (PSA) backing options to streamline installation and part placement.
