摘要:
Disclosed herein is a multilayered sheet comprising a core layer comprising a thermoplastic polymer and an IR absorbing additive; a first cap layer comprising a thermoplastic polymer and an electromagnetic radiation absorbing additive; wherein a surface of the first cap layer is disposed upon and in intimate contact with a surface of the core layer. Disclosed herein too is a method for manufacturing a multilayered sheet comprising melt blending a composition comprising a thermoplastic polymer and an IR absorbing additive to produce a core layer; melt blending a composition comprising a thermoplastic polymer and an ultraviolet radiation absorber to produce a first cap layer; combining the core layer with the first cap layer in such a manner that the cap layer is disposed upon and in intimate contact with a surface of the core layer.

Disclosed herein is multilayered sheet comprising a core layer comprising a thermoplastic polymer and an IR absorbing additive; wherein the IR absorbing additive is a metal oxide; and a first cap layer comprising a thermoplastic polymer and an electromagnetic radiation absorbing additive; wherein a surface of the first cap layer is disposed upon and in intimate contact with a surface of the core layer. Disclosed herein too is a method for manufacturing a multilayered sheet comprising melt blending a composition comprising a thermoplastic polymer and an IR absorbing additive to produce a core layer; melt blending a composition comprising a thermoplastic polymer and an ultraviolet radiation absorber to produce a first cap layer; combining the core layer with the first cap layer in such a manner that the cap layer is disposed upon and in intimate contact with a surface of the core layer.
摘要:
A composition is disclosed, comprising a polycarbonate resin, an inorganic infrared shielding additive, and carbon black, wherein an article prepared from the composition has the inorganic infrared shielding additive present at about 0.01 to about 1.0 grams per square meter, and carbon black present at about 0.001 to about 2.0 grams per square meter. The article prepared from the composition meets at least one scale requirement for European Norm EN 169 and/or EN 171, and is useful for preparing infrared shielding protective eyewear with low haze.
