Electrical conduction in polyethylene terephthalate and polyethylene films [PDF]

Journal of Physics D: Applied Physics, 1971
Electrical conduction is studied in polyethylene terephthalate and to a limited extent in polyethylene over a range of fields up to 12×106 V cm−1. In common with previous investigations, it is found that the current decays with time according to an inverse power law, but this can be obviated by a conditioning procedure which then allows steady values ...

Morphological investigations of polyethylene fibre reinforced polyethylene

Polymer, 1999
The crystallisation behaviour and morphology of polyethylene-based single polymer composites has been investigated by light microscopy and low voltage scanning electron microscopy techniques. The surface crystals on ultra high molecular weight polyethylene fibres act as nucleation centres for the high density polyethylene matrix, which may result from ...

Improvement of the Properties of Polyethylene with Chlorinated Polyethylene (CPE) [PDF]

Polymers and Polymer Composites, 2003
Blends of high density polyethylene (HDPE) and chlorinated polyethylene (CPE) have been tested across the whole concentration range. Polyethylene is used to modify the properties of CPE in the elastomer industry, but modification of the properties of polyethylene with CPE is still not usual.

Adhesion of a pair of polyethylene moldings by polyethylene gels

Colloid & Polymer Science, 1987
It was found that polyethylene gels in solvents such as benzene, toluene, xylene, decalin, tetralin, tetrachloroethylene, 1,1,2,2-tetrachloroethane, and chlorobenzene are effective for adhesion of a pair of polyethylene plates. In particular, the adhesion strength of polyethylene gels in decalin, tetralin and tetrachloroethylene was strong enough for ...

Polyethylene

1995
Publisher Summary This chapter provides an overview on the utilization of various types of welding processes to bond Lupolen, a low density polyethylene (PE) polymer. Due to their thermoplastic nature, Lupolen and Lucalen moldings and film can be welded together by the application of heat and pressure.

Study of crystallization of industrial polyethylene and polyethylene mixtures

Polymer Science U.S.S.R., 1979
Abstract Depolarization of linear polarized light was used to examine isothermal crystallization of industrial PE distinguished by the method of synthesis. The temperature dependence of the half-life of crystallization was derived. A study was made of the structure of low and high density PE mixtures, according to their behaviour during ...

Photocrosslinking of polyethylene. II. Properties of photocrosslinked polyethylene

Journal of Polymer Science Part A: Polymer Chemistry, 1989
AbstractSome properties of photocrosslinked high density polyethylene (2 mm thick sheets) have been studied. The homogeneity of the network is greatly improved by the application of triallylcyanurate (TAC) as crosslinking agent. The role of TAC in promoting the crosslinking is discussed.

Permeability to liquids of polyethylene and irradiated polyethylene

Journal of Polymer Science, 1957
AbstractPermeability constants at four temperatures for twelve organic solvents in three polyethylenes and one electron‐irradiated polyethylene are reported, together with some swelling data, and compared with data on N2, O2, CO2, and CH3Br. Irradiation appears to increase permeability and solubility coefficients for large penetrants at low ...
