Performance Features of SVW™ EW-3201S in Industrial Applications
1. Exceptional Barrier Performance for System Protection
In automotive fuel tanks, SVW™ EW-3201S acts as the core barrier layer that prevents fuel vapor permeation, ensuring compliance with stringent global emission standards such as EURO 7 and PZEV.
In underfloor heating systems, SVW™ EW-3201S blocks oxygen diffusion into closed water circuits, effectively preventing corrosion of metal components.
2. Long-Term Stability Designed for Lifetime Service
Industrial systems are expected to operate reliably for decades. SVW™ EW-3201S is engineered to meet these requirements through:
- Excellent creep resistance under continuous load
- Strong environmental stress crack resistance (ESCR) in aggressive media such as ethanol-blended fuels or heated water
- Stable mechanical properties under thermal cycling and pressure fluctuations
Whether supporting fuel loads in a vehicle over its full service life or maintaining hydraulic stability in heating pipes for more than 50 years, SVW™ EW-3201S delivers consistent long-term performance.
3. Mechanical Synergy in Multilayer Structures
SVW™ EW-3201S is rarely used alone. Instead, it is integrated into multilayer co-extruded structures, where it works synergistically with materials such as PE, HDPE, PEX, and tie resins.
In fuel tanks, SVW™ EW-3201S provides a thin but highly effective barrier layer without compromising impact resistance.
In heating pipes, SVW™ EW-3201S is protected from moisture while maintaining continuous oxygen-blocking performance.
This multilayer design approach allows SVW™ EW-3201S to achieve high performance with minimal material thickness, enabling lightweight, cost-efficient, and durable industrial solutions.
4. Compliance with Global Standards and Regulations
EVOH-based industrial solutions support compliance with the world’s most demanding regulations:
- Ultra-low fuel permeation limits for automotive applications
- Long-life and energy-efficiency requirements in green building standards
