Surface treatment systems are available for virtually any surface format including dimensional objects, sheets and roll goods that are handled in a web format. Corona treatment is a widely used surface treatment method in the plastic film, extrusion, and converting industries. [1] [2]
Polycarbonate is mainly used for electronic applications that capitalize on its collective safety features. A good electrical insulator with heat-resistant and flame-retardant properties, it is used in products associated with power systems and telecommunications hardware. It can serve as a dielectric in high-stability capacitors. [6]
Poly(glycolide-co-trimethylene carbonate) is a commercial monofilament used for suture with slow biodegradation rate which allows maintenance of high mechanical strength compatible with the surgical recovery. [9] Poly(caprolactone-co-trimethylene carbonate) has been proposed as biomaterial for conduits in the regeneration of central nervous system.
Researchers from the University of British Columbia have developed a "groundbreaking coating" that could make blood-contacting devices safer. Dr. Jayachandran Kizhakkedathu discusses the benefits.
In 2003, U.S. consumption was 856,000 tons, 72% of which used to make polycarbonate plastic and 21% going into epoxy resins. [8] In the U.S., less than 5% of the BPA produced is used in food contact applications, [9] but remains in the canned food industry and printing applications such as sales receipts.
BPA is used to form a number of flame retardants used in plastics. [61] Bromination of BPA forms tetrabromobisphenol A (TBBPA), which is mainly used as a reactive component of polymers, meaning that it is incorporated into the polymer backbone. It is used to prepare fire-resistant polycarbonates by replacing some bisphenol A
Typically used to treat breast cancer, tamoxifen has been shown to prevent the progression of Peyronie’s disease in vitro when combined with the ED medication tadalafil. The applicability of ...
Other types of organ dysfunction can occur in the systems of the body, including the gastrointestinal, respiratory, and urological systems. Implants are used in those and other locations to treat conditions such as gastroesophageal reflux disease, gastroparesis, respiratory failure, sleep apnea, urinary and fecal incontinence, and erectile ...
