WebNov 10, 2024 · Whitening agents / optical brighteners are additives that impart brightness to polymers and intensify the degree of whiteness. These agents function on the basis of the ‘fluorescence effect’; they absorb light in the UV spectrum and emit light in the blue region of the visible spectrum to yield a brighter and fresher appearance to the plastic. WebApr 15, 2024 · This review focuses on recent developments in additive manufacturing (AM) of precision optical devices, particularly devices consisting of components with critical features at the micro- and nanoscale. These include, but are not limited to, microlenses, diffractive optical elements, and photonic devices.

Whitening Agents / Optical Brighteners: Additives for Plastics

WebIn the broadest sense, additive manufacturing is a process for creating 3D objects directly from CAD (computer aided design) files. While there are quite a variety of additive techniques, they all share a common approach. First, the system software renders the object design into a series of slices, and then controls a machine that deposits ... WebOptically active additive (OAA) is an organic or inorganic material which, when added to a coating, makes that coating react to ultra violet light. This effect enables quick, non … WebJun 1, 2003 · Optical brighteners, also known as fluorescent whitening agents, are additives that alter the visual properties of polymers. Optical brighteners have been used for many years to improve the colour of various plastics. They mask inherent yellowness in discoloured polymers and impart unique, robust colour to speciality plastic products. jopベテラン 登録
