Packing Including: 18 Sheets 50cmX25cm Butyl Sound deadening Advantages of butyl rubber: Thermal stability Butyl rubber vulcanized rubber has excellent heat stability sulfur vulcanized butyl rubber can be used in the air for a long time at 100℃ or slightly lower temperature. Electrical performance The electrical insulation and corona resistance of butyl rubber is better than that of general synthetic rubber, the volume resistivity is 10-100 times higher than that of general rubber, the dielectric constant of (1kHz) is 2-3 power factor (100Hz) is 0.0026.

Chemical stability The high saturation structure of butyl rubber makes it have high chemical stability. Butyl rubber is particularly resistant to animal and vegetable oils. Butyl rubber has good corrosion resistance to most inorganic and organic acids Low temperature Although there are more methyl groups in the molecular chain of butyl rubber, each pair of methyl groups distributed on both sides of the spiral is staggered by an Angle, so the butyl rubber molecular chain is still quite smooth. The glass transition temperature is lower and the elasticity is better. Air permeability The densely-arranged lateral methyl groups in the butyl rubber molecular chain limit the thermal movement of polymer molecules. Therefore, low permeability and good air tightness. Water absorption Butyl rubber has very low water permeability, and its water absorption rate at room temperature is lower than that of other rubber, only 1/10-1/15 of the latter. Energy absorption The molecular structure of butyl rubber lacks double bonds, and the distribution density of methyl group in the side chain is relatively high, so it has good vibration and impact energy absorption characteristics. The springback characteristics of butyl rubber under a wide temperature range (-30--50℃) are not more than 20%, which indicates that the mechanical property absorption ability of butyl rubber is superior to that of other rubber. Ozone resistance and weather aging resistance The high saturation of the butyl rubber molecular chain enables it to exhibit high ozone resistance and weather aging resistance, 10 times that of the dry natural rubber.
