Close Cell And Open Cell EPDM Rubber Foam Aging Resistance For
Construction
Closed cell EPDM Foam Rubber:
The internal cells of EPDM closed cell pore foam material are
separated by cell wall membranes, they don’t link
together,belonging to independent cell structure, and mainly are
the smaller bubble hole shape or extremely small micropore.
Excellent property of resistance to oil-induced degradation or
thermal aging, widely used in electronics,automobile,home appliance
and aerospace industry as gasket,shock/vibration absorber,sound
proofing materials.
Open cell EPDM Foam Rubber:
The Internal cells of EPDM open cell pore foam material are link
together with each other and also link with the outer skin, belongs
to non-independent cell structure, and mainly are larger bubble
holes or rough holes.Excellent properties of resistance to
high-temperature aging and flame retardant,commonly used in air
conditioning,automobile,vibration and sound absorber.etc.
