One of the main focuses on automotive engine design in the last number of years has been a move towards engine compactness in an effort to increase cabin space. This has lead to a dramatic increase in temperature around the engine compartment from ar

Part I. A range of polyethylene films were prepared from metallocene linear low density polyethylene (m-LLDPE), linear low density polyethylene (LLDPE) and ultra low density polyethylene (ULDPE) resins, containing 0 and 8% polyisobutylene (PIB). FTIR

A range of samples were prepared from a commercial styrene butadiene rubber (SBR), over a range of cure temperatures (140dC-170dC) and cure times (30–120 min), using a high temperature moulding press held at a constant pressure of 5000 psi. Mechani

The incentive for this research is a result of the current issues arising over the use of flexible polyvinyl chloride (PVC) in medical devices, particularly with respect to their disposal and the use of migratory low molecular weight plasticisers. Th

The rate of moisture permeation through paper carton boards can be critical in high peformance packaging applications. Moisture barrier paperboards have been developed using aqueous-based emulsion polymers, and the results obtained with these materia
