Product format: Weekly e-mail

Every week when the Polymer Library abstracts database is updated with new records, you will be sent a bulletin alerting you to any items that relate to this topic.

Description

The usage of blowing agents (used to create foamed, cellular and hollow materials) in the rubber and plastics industries was hugely affected by the 1987 Montreal Protocol, which set international targets on the use of ozone-depleting gases such as chlorofluorocarbons. CFC-11 was entirely phased out throughout the world by 2010.

As a result common replacements include cyclopentane in Europe and HCFC-141b in the USA, Asia and the Pacific (but with cyclopentane gaining popularity in the latter two). Most interesting, however, is the rapid increase in the use of carbon dioxide in various foaming technologies, primarily due to its low cost and high blowing capacity, but also due the unusual physical properties of the resultant foams. Understanding the legislative requirements for blowing agents is an ongoing necessity for all those involved with foam applications.

A Current Awareness service from Smithers Rapra may be just what you need to update your knowledge with ease and accuracy without having to waste time, effort and money finding the information yourself. Get in touch to find out more.
