On behalf of the Polycarbonate/BPA Global Group of the American Chemistry Council (ACC), I am submitting these comments in response to OEHHA’s Notice of Proposed Rulemaking regarding the proposed Maximum Allowable Dose Level (MADL) for bisphenol A (BPA). The Polycarbonate/BPA Global Group consists of the leading global manufacturers of BPA and polycarbonate plastic, which for many years have su...

UNLABELLED The human opportunistic pathogen, Acinetobacter baumannii, has the propensity to form biofilms and frequently cause medical device-related infections in hospitals. However, the physio-chemical properties of medical surfaces, in addition to bacterial surface properties, will affect colonization and biofilm development. The objective of this study was to compare the ability of A. bauma...

1. Production of polycarbonate Polycarbonate (PC) is an amorphous, thermoplastic and transparent plastic. Current annual production of polycarbonates amounts to two million tons worldwide and expected to increase about 5-10% annually (Ref [1],[2]). At present, PC is made mainly by a phosgene-based technique. Phosgene is highly toxic and considered a serious pollutant. DMC can provide an environ...

The widespread application of thermoplastic polymers in different aspects of industries has motivated researchers and companies to improve and upgrade their forming, joining and assembling processes to overcome their limitations. One of the newest joining methods of thermoplastics is friction stir welding which is based on frictional heat generated through contact between a rotating tool and th...

Mechanofluorescent polymer probes were used to visualize stresses and bond scission in polystyrene polycarbonate. Sonication of with a molar mass 1.1 × 105 g·mol–1 solution resulted 30% activation after 1 h, while shorter showed lower percentages. Single-asperity sliding friction tests performed on mechanophore-containing polycarbonate films. Polystyrene clearly visible crack formation correlat...
