Acceleration parameters have been determined for bisphenol A polycarbonate (PC) exposed to blue light emitting diodes (LED) in a commercial apparatus for testing optical components using absorbance at 360 nm as a proxy for yellowing. The effect of te

Microbial growth, presumably fungus or mildew, has been found growing on samples of aromatic engineering thermoplastics after 6–24 months of outdoor exposure at Miami, Florida test sites. Similar growth has been reported on automotive coatings, and

A series of 31 aromatic engineering thermoplastic formulations was exposed at outdoor sites in Florida, Arizona, and the Kingdom of Saudi Arabia (KSA) for 24 months as well as under modified ISO 4892-2 xenon arc accelerated weathering conditions. The
The NIST (National Institute of Standards and Technology) SPHERE (Simulated Photodegradation via High Energy Radiant Exposure) was used to obtain acceleration parameters, such as activation energies, for bisphenol A polycarbonate (PC), poly(butylene

A series of 31 aromatic engineering thermoplastics was exposed to modified ISO 4892-2A xenon arc accelerated weathering and to natural weathering in Miami, Florida and two desert sites. The xenon arc conditions were chosen to give rational accelerati

Predicting outdoor service life of polymers and coatings requires knowledge of the spectral power distribution (SPD) of the sunlight and the amount of radiant energy they receive. Standard solar SPDs such as ASTM G173 and ASTM G177 are snapshots of t

Free radical chain autoxidation is the primary oxidation mechanism for many polymers, but it is not the only way that organic materials can react with oxygen. Organic chemists have identified several ways that molecular oxygen can react directly with

Service life prediction, in general, and weathering lifetime, in particular, have been persistent problems despite nearly a century of work. Part of the problem has been a gap between the work of scientists studying material degradation and the pract
