Epdm foam strip is made by adding chemical foaming agent into epdm, after high temperature foaming and curing finalize the design of a cross section of a honeycomb structure of the foam strip, has the following features: - - - - - - - Low density: there are a large number of bubbles in foam strip, its density is about 0. 5 to 0. 6 g/cubic centimeters, for the common strip half or even lower. - - - - - - - - - - - - Good sound insulation effect: foam strip in the sound insulation effect is through the absorption of acoustic energy, to reflect sound waves can't pass. - - - - - - - - - - - - Excellent thermal insulation: because there is a lot of bubbles in the foam strip hole, gas hole the bubble of much lower thermal conductivity than solid rubber, so the foam strip thermal conductivity is very low. - - - - - - - - - - - - Than the intensity is high, because of the low density, specific strength than the natural high foam products, foam strip with the increase of the expansion ratio and mechanical strength of the decline. - - - - - - - - - - - - Excellent heat resistance, chemical resistance, more excellent than solid rubber compression resilience and low tender and soft. seals manufacturer - dongguan , 17 years focused on custom all kinds of seals, sealing ring, rubber sealing products, has formed the raw material preparation, mold development, product molding one-stop production mode, production of foam strip: micro pore structure density, irregular aperture size is the same, density is small, stable geometrical dimension and smooth surface are of good quality and can be widely used in sealing, shock absorption, sound insulation, heat insulation, electrical and mechanical industries.
