FAQs
Explore our FAQs for quick answers to common questions. For deeper insights, check out:
1. Do your elastomers withstand high radiation exposure?
Yes. Our EPDM, silicone, and FKM materials are engineered and tested for prolonged ionizing radiation environments.
2. Are your seals suitable for nuclear containment doors and safety systems?
Absolutely. We manufacture inflatable seals, extrusions, and molded gaskets designed for containment, emergency shutdown mechanisms, and controlled-zone enclosures.
3. Do your materials tolerate extreme temperatures and pressure cycling?
Yes. Our compounds are engineered to withstand –40°C to +200°C, steam, chemical exposure, and rapid pressure variations common in nuclear systems.
4. Do you offer batch traceability and nuclear-grade documentation?
Yes. We provide complete documentation packages, COAs, batch traceability, and manufacturing records aligned with nuclear safety requirements.
5. Can you manufacture seals for non-standard geometries and large structures?
Yes. Our in-house CNC tooling and rapid prototyping enable custom seals for unique hatches, access doors, and reactor equipment.
6. Are your sealing solutions tested for long-term compression set and durability?
Yes. Our nuclear-grade formulations maintain sealing force, elasticity, and dimensional stability over extended life cycles.
7. Are your products manufactured under certified quality systems?
Yes. All nuclear sealing solutions are produced under ISO 9001-certified quality systems with rigorous QC and controlled processes.
