Micro-Structure & Special Properties

1. Closed-Cell vs. Open-Cell Options
Closed-Cell Foam (EVA, EPDM, PE, CR, Closed-Cell Silicone): Independent sealed bubbles prevent gas and liquid passage. Best for waterproofing, dustproofing, weatherproofing, and airtight sealing.
Open-Cell Foam (PU, Open-Cell Silicone/Sponge): Interconnected pore structure allows air and sound waves to pass through. Best for sound absorption, air filtration, thermal dissipation, and ultra-soft cushioning.
2. Flame Retardant & Conductive Grades
UL94 V-0 / HF-1 Fire Retardant: Available across Silicone, CR, and EPDM materials for high safety electrical applications.
ESD / Conductive / Anti-Static Foam: Available in EVA and PE materials for sensitive electronic component shipping and assembly.
