Biodegradable plastic additives have been breakthrough

2023-03-08 05:07:51
The Shanxi Academy of Chemical Research recently successfully developed a special nucleating agent for bio-based plastics and biodegradable plastics for the TMC series, marking a major breakthrough in the field of bio-based plastics and additives for biodegradable plastics. According to the person in charge of the Shanxi Provincial Institute of Chemical Industry, the newly developed TMC series dedicated bio-based plastics and biodegradable special nucleating agents include TMC-300 and TMC-306, which are innovative hydrazide compounds. Non-toxic and odorless, it is a special nucleating agent for bio-based plastics such as polylactic acid and biodegradable plastics.

High Precision Optical Glass Window

Windows are optical glass with ground and polished faces that are relatively parallel.They are used to isolate two physical environments while allowing light to pass.Windows made of BK7 material have high transmission in the visible spectral region, do not scratch easily, do not degrade under normal operating environment and hence do not need any special precaution or treatment. Anti-Reflective Coating will provide higher transmission.
China Star Optics offers all types of windows made from different materials. Such as N-BK7, Fused silica, sapphire,CaF2, Silicon, Borofloat, high borosilicate glass and other optical glass supplied by Schott and Chinese CDGM are available upon request.

Windows at shape of round,quadrate, triangular or other polygonal are also available upon request.In addition, we provide a variety of single layer or multiplayer anti-reflecting coating,HR,PR coatings on Optical Windows.
