/ Product description
With microwave vulcanization process,surface is bright and clean with no lapping defect.
Good elasticity and compression deformation resistance,excellent aging resistance.
The function :heat insulation,sound-proof and dust-proof improve the air tightness and water tightness of the window and door.
Different design for different profile,no wrinkle of the edge.High performance of sealing.shock proof,dust proof and oil proof.
EPDM can resist the ozone attack completely.Under ozone environment,EPDM has no crack,can be used long time under the sun,damp and cold environment (-50 degree~-120 degree)
Material performance perform:The GB/T 24498-2009 building doors and winodws,curtain wall sealing strip.Size tolerance perform:The tolerance of GB/T3672.1-2002 rubber products Part 1: size tolerance
