Polyurethane Foam
PORON® AquaPro Series
Overview
The PORON® AquaPro® Series includes multiple softness levels of polyurethane foam, specifically engineered to deliver enhanced water-sealing performance and long-term reliability. This series features:
- PORON® AquaPro® 4701-37 (Very Soft)
- PORON® AquaPro® 4701-41 (Soft with enhanced closed-cell content)
These foams offer excellent sealing ability with low compression force and are designed to maintain durable performance even under harsh environmental conditions.
Features
- Superior water-sealing capability, ideal for moisture and vacuum sealing applications
- Multiple softness grades, catering to both low-force sealing and tight seal retention
- Thermally stable, performing reliably from –40 °C to 90 °C (constant use) and up to 120 °C (intermittent use)
- Flame-resistance — Meets UL 94 HBF and FMVSS 302 standards
- Low outgassing and absence of plasticizer migration support sensitive applications
- Chemical resistance to automotive fluids, providing long-term durability under exposure
Benefits
- Effectively protects against water ingress, even in compact or tight-seal designs
- Maintains sealing performance across a wide temperature range and over time
- Ideal for delicate applications requiring soft sealing or high performance under compression
- Supports flexible manufacturing through availability in sheets, rolls, or custom die-cut parts
Applications
- Waterproof gaskets and seals in electronics, lighting, HVAC, and battery enclosures
