A rapid method for assessing the resistance of polyurethanes to biodeterioration.

摘要: Abstract A rapid soil burial method for assessing the susceptibility of polyurethanes to biodeterioration was developed. The time test reduced by prestressing polyurethanes. degree deterioration measured following changes in appearance and selected physical properties. It found that pre-stressing produced significant reductions tensile strength a known susceptible polyurethane after 2 weeks. reduction greater than with unstressed buried 26 weeks active soil. Changes were less 4 sterile same period. results suggest during is result both chemical microbial action.
