The Resin Identification Code (RIC) is a technical standard with a set of symbols appearing on plastic products that identify the plastic resin out of which the product is made. [1] It was developed in 1988 by the Society of the Plastics Industry (now the Plastics Industry Association ) in the United States, but since 2008 it has been ...
Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process. The presence on an item of a recycling code, a chasing arrows logo, or a resin code , is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.
Other applications, including polycarbonate sheets, may have the anti-UV layer added as a special coating or a coextrusion for enhanced weathering resistance. Polycarbonate is also used as a printing substrate for nameplate and other forms of industrial grade under printed products. The polycarbonate provides a barrier to wear, the elements ...
CR-39 is made by polymerization of ADC in presence of diisopropyl peroxydicarbonate (IPP) initiator.The presence of the allyl groups allows the polymer to form cross-links; thus, it is a thermoset resin.
Demand for plastic resins in Europe during 2017 as a percentage of total plastic demand. [1] A comparison of standard plastics, engineering plastics, and high-performance plastics
ASA/PC (polycarbonate) blends have been prepared and are commercially available. [ 12 ] [ 13 ] In the Fused Filament Fabrication 3-D printing process, the ASA filament is used to fabricate 3-D printed parts, which above all must absorb a certain amount of impact and impact energy without breaking.

The third College Football Playoff rankings will be released Tuesday with some major questions looming for the committee to answer.
Polycarbonates do not have a unique resin identification code. Items made from polycarbonate can contain the precursor monomer bisphenol A (BPA). Susceptible to UV light, exposure results in yellowing (degradation is especially visible in headlamps that lost or didn't have proper protective coating).
