Product Detail

EPDM Closed-Cell Foam

Closed-cell EPDM foam products are engineered with a sealed cellular structure that prevents 

air and moisture penetration,making them ideal for demanding industrial and commercial 

applications. These foams excel in waterproofing, thermal insulation,and vibration damping.

Base on the normal EPDM foam, DUTE has pioneered proprietary 

technology to produce sulfur-free EPDM foam, which is a new standard in quality and performance. 

This innovative sulfur-free foam is particularly well-suited for demanding applicationsin the automotive, 

electronics, and semiconductor industries, where superior material purity and environmental 

considerations are critical.

EPDM Semi-Closed Cell Foam

DUTE offers Semi-closed cell EPDM foam which combines a hybrid cellular structure, blending 

isolated and interconnected pores to balance impermeability with controlled flexibility. This material 

is tailored for scenarios requiring moderate environmental resistance alongside dynamic stress 

absorption. Its unique architecture ensures adaptability across industries where partial airflow or 

moisture regulation is advantageous, without compromising durability. Applications include HVAC 

system gaskets (for condensation control), architectural expansion joints, sports equipment 

cushioning, and automotive interior components like door seals. Its versatility bridges the gap 

between rigid sealing and soft cushioning, making it indispensable for modern engineering challenges.

EPDM Open-Cell Foam

Open-cell EPDM foam features a porous, interconnected structure that enables air and moisture 

permeability while retaining lightweight flexibility. Designed for applications prioritizing breathability, 

acoustic absorption, and cushioning, this material balances softness with structural integrity, offering 

unique advantages in environments where airflow or energy dissipation is critical. 

DUTE’s Open-cell EPDM foam is widely adopted in automotive interiors (e.g., seat cushions, headliners), 

HVAC air filters, medical equipment padding (for pressure redistribution), and sports gear like yoga 

mats. Its breathability also suits green building designs, such as acoustic wall panels or eco-friendly 

insulation layers requiring moisture management. Unlike closed-cell variants, it prioritizes comfort 

and adaptability over rigid sealing, making it essential for industries where user comfort and 

environmental interaction coexist.
