Based on the characteristics of rubber, our company has developed soluble rubber, which is mainly prepared from polyurethane rubber and some catalysts. It can swell and dissolve in a certain medium solution at a certain temperature.

By studying the factors that promote rubber aging and degradation, controllable management of rubber aging and degradation time can be achieved to meet the needs of tool applications. Underground tools often come into contact with downhole fluids (including formation water, formation oil and gas, injection water, drilling mud, special working fluids, etc.), and the aging and degradation mechanisms of rubber products of downhole tools mainly consider fatigue aging degradation and hydrolysis aging degradation. Our company has developed rubber cylinders suitable for different temperatures and mineralization levels, which are compatible with our bridge plug products.
