PMMA (Acrylic) light diffuser is embedded with specific optical chemicals. It creates a snow-white color, brighter, and more uniform effect for back-lit lightbox, ceiling lighting, and other decorative applications. Various colors such as red, blue, yellow are also available. thickness: 3, 5mm finish: gloss, single-matte, double-matte size: 800mm x 1220mm UV stable: upon request by order
Optical brightener KSN and OB-1 have similar chemical structures, and Optical brightener KSN has better whitening effects on PC and plastics than OB-1, and its compatibility is also better than OB-1.Optical brightener KSN also has high temperature resistance. But it is also more light and weather resistant than OB-1. KSN is suitable for whitening PA, PAN, film, injection/extraction molds. Optical Brightener KSN Pure Powder 99%min with CAS No. 5242-49-9.
Optical Brightener KCB is bright yellow powder with melting point 212â??, it is insoluble in water and the maximum absorption wave length is 370nm. It has very high stability and very excellent weather resistance and migration resistance, so it is very popular and very widely used in Plastic, Coating, Painting, Ink, Copolymer, Synthetic fiber, Polyester fiber etc. Optical Brightener KCB Pure Powder 98.5%min with CAS No. 5089-22-5.
Optical brightener FP-127 is a heat-resistant, solvent-soluble, chemically stable optical brightener that provides better color. It is used to offset the yellow color of the polymer and produce a whiter appearance. Optical brighteners change the wavelength of light by absorbing ultraviolet light, and then emit light in the form of fluorescence. It can also be used as a tracer in various applications and as an optical brightener in thermoplastics, coatings, printing inks, dyes, man-made fibers, waxes, fats and oils. This fine powder form is very suitable for: 1.) Reducing the clogging of the equipment is essential to increase productivity and 2.) It is essential for the application efficiency of the clear coating to disperse and smooth the appearance of the coating. Optical Brightener FP-127 Pure Powder 99%min with CAS No. 40470-68-6.

Products Information: Products Name: OPTICALBRIGHTENER OB-1; Color Index No: C.I.393 Synonyms: FBA 393; OBA 393,Fluorescent Brightener OB-1; Optical Brightener Agent OB-1 Molecular Formula:C28H18N2O2 Molecular Weight:414 CAS No:1533-45-5 EINECS No: 216-245-3 Appearance: Light yellowish green powder Melting point:358 Assay:98.5% Fineness: 200 meshes Molecular Structure: Features Optical Brightener OB-1has excellent high temperature resistance. It has wide range ofapplication, and is used for the whitening of nylon fiber, polyesters, andvarious plastics. It has outstanding brightening ability and gooddispersibility. It also has good adaption and weather resistance Applications OpticalBrightener OB-1 can be used on polyester fiber, nylon fiber, polypropylene,hard PVC, ABS, EVA, PS, polycarbonate etc. For high temperature resistantplastics, only ob-1 can be used, and the addition amount of optical brightenerob-1 is small and the whitening degree is high. Reference dosage: Every 1000kg materials to add OB-1 brightener: 1, EVA, polypropylene, nylon, polycarbonate in the amount of 75-200 g. 2. The adding amount of polyester fiber is 75g- 300g Package & Storage: 10kg or 25kg/ fiber drums. It can bepacked in other forms according to user's requirements. Shelf life: not more than 24 months inthe room temperature.
Brewster window use the characteristics of total reflection property of the material. When the incident Angle (called brewster Angle of the material) is specified, the Polarization component of S in the incident light is partially reflected, while the P component is close to the full transmission.Sunday offers a variety of Brewster Windows based on UV-fused quartz for UV applications The high-precision window is made of BK7 optical glass and UV fused quartz, the fused silica quartz window plate is suitable for high power laser that needs good thermal stability, and the window made of N-BK7 material is cheaper, which is suitable for laser applications that pay more attention to cost.Both fused quartz and N-BK7 laser window plates have precision grades of 1/10 lambda surface flatness and 10-5, 20-10 surface quality to ensure minimal interference to the transmitted beam.Sunday Optics is specialized in the processing of precision optical window,We have four-axis polishing machine, large-size ring polishing machine, two-axis machine to manufacture high precison windows for customers. we can offer 24 inch zygo flatness reports, full CA 600mm windows.Brewster window use the characteristics of total reflection property of the material. When the incident Angle (called brewster Angle of the material) is specified, the Polarization component of S in the incident light is partially reflected, while the P component is close to the full transmission.Sunday offers a variety of Brewster Windows based on uV-fused quartz for UV applications Specifications Diameter 10mm to 127mm Diameter Tol. +/-0.02mm Material JGS1 Surface Quality 10-5 standard Flatness 1/10 lambda Parallisam
