A lens barrel includes a lens containing resin, and a lens holder configured to hold the lens via an adhesive. The lens includes a first area, and a second area, the adhesive being applied to the second area, and the second area being adhered to the lens holder and containing more oxides or modified materials of the resin than the first area.

Polymer compositions include a recycled polyamide and an electronic device and a protective case for an electronic device including the same. The polymer composition according to various embodiments of the present disclosure may include a recycled polyamide, a new polyamide including at least one polyamide component, a glycidyl group-modified ethylene-octene-based copolymer, and an inorganic filler. In some embodiments, the recycled polyamide may include a polyamide collected from marine plastic waste.

This invention relates to a polymeric pipe, and more particularly a polymeric pipe where the pipe comprises a cross-linked polyolefin formed from extruded polyolefin comprising a bismaleimido crosslinker. This invention relates to the manufacturing of plastic pipes and tubing of polyolefinic polymers such as polyethylene, with crosslinking by a bismaleimido crosslinker, to produce crosslinked polyethylene (PEX) pipes and tubing.
