Abstract: |
Phenolic foam exhibits a series of excellent performance such as flame retardancy and heatAbstract: The nonlinear dynamics equation is developed for suspension-type package system with the rubberinsulation. However, the brittleness and pulverization of phenolic foam have greatly limited its application inAbstract: The nonlinear dynamics equation is developed for suspension-type package system with the rubbermany fields. In this paper, expandable phenolic resin and polyurethane prepolymer were firstly synthesized,Abstract: The nonlinear dynamics equation is developed for suspension-type package system with the rubberand then the foaming formula and processing of toughening phenolic foam modified with polyurethaneAbstract: The nonlinear dynamics equation is developed for suspension-type package system with the rubberprepolymer were explored. The effects of polyurethane prepolymer on the compression strength, water intake,Abstract: The nonlinear dynamics equation is developed for suspension-type package system with the rubberoxygen index and pulverization of modified phenolic foam were also discussed. The results showed that theAbstract: The nonlinear dynamics equation is developed for suspension-type package system with the rubberapparent density, compression strength, water absorption and anti-chalking of the modified phenolic foamAbstract: The nonlinear dynamics equation is developed for suspension-type package system with the rubbertended to increase with the increasing content of polyurethane prepolymer, whereas the oxygen index showedAbstract: The nonlinear dynamics equation is developed for suspension-type package system with the rubbercounter trend, which dropped to 30 when the content of polyurethane prepolymer was 15%.
