Explore adhesion and bonding to
polyolefins
Many applications of polyolefins require good adhesion to other substrates. A report discusses ways of improving adhesion to substrates.
Many applications of polyolefins require good adhesion to other substrates, in processes such as adhesive bonding, lamination, painting, printing and metallisation However, polyolefins have very poor bonding properties except where a diffusion mechanism operates such as during the welding together of two pieces of polyolefin

The latest report in the Rapra Review Report series from Rapra Technology, Europe's leading independent plastics and rubber consultancy and publishing house, discusses ways of improving adhesion to substrates.
A variety of pretreatments and primers have been developed for altering the surface properties of polyolefins to enhance adhesion.
These include corona discharge, flame and low pressure plasma treatment for plastics and the use of a chlorine donor for elastomers.
Data from some of the key work on different treatment methods are included in this review, together with a discussion of the effectiveness of the treatments.
A number of different analytical methods have been used to characterise the surface of polyolefins before and after treatment.
These include X-ray photoelectron spectroscopy (XPS), static secondary ion mass spectrometry (SSIMS) and Fourier transfer infrared spectroscopy (FTIR).
These techniques are described and examples of the information obtained are given.
The authors are researchers at the Institute for Surface Science and Technology at Loughborough University, Dr Brewis has carried out research in the field of polyolefin adhesion over several decades and has published extensively.
Dr Mathieson has recently completed a doctoral thesis on this topic.
Rapra Review Reports contain a state-of-the-art review, written by an acknowledged expert in the field, together with several hundred of the most relevant references and abstracts identified from the Rapra Abstracts database.
Thus they provide both a concise, readable introduction to the subject and the means of investigating key points in greater depth.
The report retails at ?80, $120, 136 Euros (plus postage and packaging) and is available, along with further details, from www.polymer-books.com or from +44 (0) 1939 250383;.
