Service life oxide stability effects

With rubber base adhesives, it is necessary to prevent their properties from changing during service life. Oxidative changes induced by thermal, ozone exposure and UV light can dramatically affect service life of rubber base adhesives. More precisely, the rubber and the resin are quite susceptible to oxidative degradation. Environmental and physical factors exert detrimental effects on rubber base adhesive performance. These effects can be mitigated by the incorporation of low levels of stabilizers during the fabrication process of the adhesive. 

The photostabilization of polymers continues to be a rapidly advancing area of scientific and technological interest. Carlsson and Wileshave written several reviews on photostabilizing mechanisms in polymers, while Swasey has given an updated guide to stabilization, and Reid has discussed the effects of stabilizers in vinyl polymers. Nemzek and Mayo have predicted the service life of polypropylene, and Bredereck has reviewed the photostabilization of PVC. Several comprehensive review articles have appeared. Pospisil has reviewed in considerable depth the photo-oxidation mechanisms of phenolic anti-oxidants, Shlyapintokh has reviewed the kinetics of stabilizer distribution, Vink has... 

The OIT method is a testing method used to evaluate the effect of stabilizers, see Section 2.1.3.4.2. However, the thermal oxidative degradation behavior of plastics and their service life cannot be predicted using this method, Figure 2.23. 

However, the use of nanoparticles in nanocomposites may also have less desirable side effects. For instance, thermo-oxidative stability may be reduced, which may have negative consequences for performance and service time [13,14]. Furthermore, polymer degradation under solar irradiation may be increased, and hazardous nanoparticles may be released during their life cycle (which starts with resource extraction and ends with final disposal) [15,16]. The release of engineered nanoparticles from nanocomposites and the scope for reduction of hazard and risk to health during the nanocomposite life cycle are considered in this chapter. This chapter also deals with other environmental aspects of...
