Investigation on the degradation behavior of polyoxymethylene (POM) in chemical aggressive environment by means of Thermogravimetric Analysis Method

Application of polymers depends significantly on the ability of their structure to stay unchanged as long as possible. Fuel system engineers have always struggled with the task ofassuring that materials used for fuel system components will survive in the fuel environment. As the usage of this polymerin the vehicle fuel pump is widespread [1], the aim of this study is to evaluate the change in key properties of plastic materials in a range of fuels. Part of the investigations was tocharacterize the degradation behavior of POM copolymer in several aggressive fuels by means of Thermogravimetric Analysis Method.
