     Description                                                        

RPA8000 Rubber Process Analyzer is an advanced test instrument, designed to measure the properties of polymers and rubber compounds before, during and after cure by dynamically changing frequency, stress, and temperature so that the processability, vulcanization properties, physical properties of polymers and rubber compounds. It can test rubber compound, crude rubber, and other thermoplastic elastomers. 
  The RPA is very highly sensitive and can detect the change in properties caused by a little composition change during production. It is characterized by easy operation, time saving, cost saving, high efficiency and multifunction, so it has been widely and flexibly used to replace many traditional equipment and tests in many areas.
