An investigation has been made of the effect of whiting on the mechanical properties of chemically crosslinked polyethylene foam. The presence of up to 15% filler has little effect on the appearance of the foam. The apparent density of the foam increases little. The characteristics of the foam under compression are improved, and its tensile strength is increased.
The effect of thermal deformation on the cellular structure and thermomechanical properties of chemically crosslinked PPE-3M polyethylene foam was investigated. The thermomechanical effects are discussed from the viewpoint of a model of the cellular structure and a twophase model of partially crystalline polyethylene. The dependence of these effects on the nature of the force effect and on the temperature when force is used at the stage of producing chemically crosslinked polyethylene foam was established.
An investigation was made of the influence of the cellular structure on the coefficient of linear thermal deformation and inverse creep of chemically crosslinked polyethylene foam PPE-3M. The dependence of deformability on the nature of the force effect and on the temperature when exposed to the force effect at the stage of production of chemically crosslinked polyethylene foam was established.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
