Foam Polyethylene Made of Recycled Polyethylene
Abstract The paper deals with the main principles of foam polyethylene production by the addition of recycled polyethylene and a modifier in the initial mixture. Obtaining of the modified foam polyethylene will accomplish two important tasks: solve the environmental problem of recycling polyethylene waste and reduce the cost of the ...

Chain-Extended Polyethylene [PDF]
The current status of high-strength/high-modulus polyethylene fibres is reviewed with the emphasis on fundamental aspects of ultra-drawing and processability. The drawing mechanism as well as the temperature dependence of the drawability of UHMW-PE (ultra-high-molecular-weight polyethylene) will be discussed.

Radio-Oxidation of Electric Cabled Models: Ageing Evaluation at the Atomic Scale
The functionality of electric cables, being the safety components of plants, has to be ensured. In nuclear power plants, when they are in the reactor building, these cables can suffer γ irradiation even in normal operating conditions.
