Microchamber sampling and TD–GC–MS analysis of chemical emissions from spray polyurethane foam (SPF) in accordance with ASTM D8142
contributed by Markes International Ltd |
Summary
This study describes the use of Markes’ Micro-Chamber/ Thermal Extractor (μ-CTE), followed by thermal desorption– gas chromatography–mass spectrometry (TD–GC–MS), to analyse volatile and semi-volatile organic compounds emitted from spray polyurethane foam, in accordance with ASTM D8142.
Introduction
Spray polyurethane foam (SPF) is a spray-applied polymer that is used to form a continuous layer on the internal surfaces of buildings. Its effectiveness as an insulator, speed of application, and compatibility with a range of surfaces means that it is widely used for building insulation and damp-proofing in the USA, and is rapidly gaining popularity elsewhere, especially in Asia and some European countries.
SPF is created on-site by mixing two liquids, known as the ‘A side’ and ‘B side’, which react and expand on contact to create a highly insulating foam that also seals gaps and forms a barrier to air and moisture
