Manganese Dioxide Structural Influence on Polysulfide Oligomers Cure Speed

Characteristics of vulcanisation process of industrial polysulfide oligomers (PSO) by MnO 2 were studied. Influence of activity of MnO 2 industrial batches on parameters and EPR line forms of vulcanising agents were ascertained. The influence of cure speed on physical and mechanical properties of tw...

Description
Summary:Characteristics of vulcanisation process of industrial polysulfide oligomers (PSO) by MnO 2 were studied. Influence of activity of MnO 2 industrial batches on parameters and EPR line forms of vulcanising agents were ascertained. The influence of cure speed on physical and mechanical properties of two sealants Y-30 M and AM-05 were analysed. It was established that activity of Mn dioxide used primarily inflaraccd speed of cats but not the deformation, durability or hardness of final product.
