High-indexplastic or glass lenses bend light more effectively than lenses made of plastic or polycarbonate material. The result is thinner and lighter eyewear that is comfortable to wear. High-index lenses are great for people with strong prescriptions. However, they are more costly than plastic o...

Aryl-terminated low-mol. polycarbonate - as plasticiser for high-mol. polycarbonate, raising melt indexLow mol. wt. polycarbonates with terminal aryl gps. have formula (I), where R is C6H5, C6H4C(CH3)3, or C6H2Hal3; R' is H, Cl or Br; Z is =C(CH3)2, =C=CCl2, or SO2;...
Based on degradation studies at different temperatures and subsequent calculation of activation energy for abiotic hydrolysis, propensity for degradation depends on functional groups and polymer structure such that PCL (81 kJ mol−1) > bisphenol A polycarbonate (PC) (92 kJ mol−1)...
(polystyrene). The non-recyclable plastic is under the category of thermosetting plastics and synthetic fibres, e.g. multilayer and laminated plastic, Teflon, PUF (polyurethane foam), Bakelite, polycarbonate, melamine and nylon. Figure3shows the classification of different plastics and their suitable...
Briefly, we withdrew 400 ml (sampling points 1, 12 and 24 h) and 200 ml (sampling points 48, 96, 168, 336 h) with sterile 1 L glass bottles and filtered the sample on a polycarbonate filter (0.2 µm). Sampling volume was less for the last four samplings as filters ...
Recovering materials for recycling includes transforming electronical waste and compounded polycarbonate into pellets [212] and pharmaceutical blister packaging using switchable hydrophilicity solvents [253]. Two pieces of research investigated polymeric blend properties that include the design of polymeric blends...
Likewise, apart from PET, other types of plastic scraps (i.e. polyethylene, polycarbonate, polystyrene, polyvinyl chloride) could also be used to make different components of the TENG device such as an alternative tribolayers, device casing and packaging. However, employing different recycled ...
