橡膠止水帶是采用天然橡膠與各種合成橡膠為主要原料，摻加各種助劑及填充料，經(jīng)塑煉，混煉，壓制成型，其品種規(guī)格較多，有橋型、山型、P型、R型、U型、Z型、乙型、T型、H型、E型、Q型等。該止水材料具有良好的彈性，耐磨性、耐老化性和抗撕裂性能，適應(yīng)變形能力強、防水性能好，溫度使用范圍-45℃-+60℃。當(dāng)溫度超過+70℃，以及強烈的氧化作用或受油類等有機溶劑侵蝕時，均不得使用該產(chǎn)品。
The rubber sealing strip is made of natural rubber and various synthetic rubber as the main raw material, and the filling material mixed with various additives, through mixing, mixing, molding, the more varieties of different specifications, bridge, mountain type, P type, R type, U type, Z type, T type, H type, type, E type and Q type etc.. The sealing material has good elasticity, wear resistance, aging resistance and tear resistance. It has good debation ability and good waterproof perbance. Its temperature range is -45 degrees centigrade and -+60 degrees centigrade. This product should not be used when the temperature is higher than +70 degrees, and it is strongly oxidized or eroded by organic solvents such as oil.
