/ Product description
Five Sponge composite seal(EPDM) Features:
1.The main strip material selection is based on Lanxess,Mistui,Kumho and other manufacturers of raw rubber EPDM,microwave curing process forming a production line.
2.Has good flexibility and resistance to compression,weather resistance,ozone resistance,chemical stability,excellent electrical insulation properties and wide temperature range (-50°C~+150°C),excellent performance.
3.Secondly,sponge foam has a good waterproof,dust,noise,compartment temperature,damping effect can be applied to a variety of doors and windows and other needs sealing,buffer areas.
4.The foam hardness range:20 to 80 degrees;low density:0.40~1.00g/cm3 .
5.The material properties of the implementation of GB/T 24498-2009 building windows and doors, curtain wall sealing strip.”
6.Dimensional tolerance execution”GB/T3672.1-2002 rubber tolerances-Part 1:Dimensional tolerances”.
