First the Feature of MVQ rubber strip
Strip material selection is based on several US manufacturers of Dow Corning, Shin-Etsu, Lansing, such as silicone rubber compound Charming, can meet most customers’requirements. Wide operating temperature silicone rubber, is the best cold, high temperature rubber. Excellent aging resistance, non-toxic, environmentally friendly; can reach the level of food hygiene requirements, to meet the requirements of various colors.

The basic properties:hardness 50-80A, ordinary silicone Operating temperature range:-80~230 degree centigrade. The material properties of the implementation of“GB/T 24498-2009 building windows and doors, curtain wall sealing strip.” Dimensional tolerances execution“GB/T 3672.1-2002 rubber tolerances-Part: Dimensional tolerances”

Second the features of EPDM rubber strip
The main material selection is based on Lanxess(Bayer), DSM, Korea Kumho EPDM and other manufactures of raw rubber, Cabot carbon black, advanced microwave curing production line.
EPDM has excellent resistance to ozone, weathering resistance, heat aging resistance, excellent electrical insulation properties: hardness 70+_5A, temperature 120-150 degree centigrade, low temperature-50 degree centigrade not broken. The material properties of the implementation of “GB/T 24498-2009 building windows and doors, curtain wall sealing strip.” Dimensional tolerances execution“GB/T 3672.1-2002 rubber tolerances-Part 1: Dimensional tolerances”.
