BRIGHTENER PL-1

FLUORESCENT WHITENING AGENT FOR PLASTICS

INTRODUCTION :

Optical whiteners function by absorbing ultraviolet radiation and re-emitting blue light.

The emitted blue light will reduce the yellowness of a polymer and provide the whiter-than-white appearance.

OPTICALWHITE PL-1 : optical brighteners significantly improve the whiteness in both textile fibers and plastics . in polyester and nylon fibers ,

OPTICALWHITE PL-1 optical brighteners impart a pleasing whiter-than-white appearance and give more intensity to some colors as well. Because of its excellent brightening ability , good thermal stability , and compatibility whit many polymers ,

OPTICALWHITE PL-1 is an effective brightener for many plastics .

OPTICALWHITE PL-1 provides an excellent white , permanent color since the brightener is dissolved in the polymer or fiber during manufacturing . this permanence gives much better brightness retention over time versus other methods such as bleaching or surface treatment with optical brighteners .

CHEMICAL NAME : 2,2'-(1,2-Ethenediylidi-4, 1-phenylene)bisbenzoxazole

EMPIRICAL FORMULA : C28H18N2O2

CAS : 1533-45-5

 

APPLICATIONS :

Thermoplastic – OPTICALWHITE PL-1 can be used to impart excellent brightness to various thermoplastics, including: polyvinyl chloride, polyethylene, polypropylene, polystyrene, polystyrene, polycarbonate, acrylics, polyolefin, adhesives, polyurethane, linear polyester, polyamides, rigid PVC and the like.

Man-made fibers – OPTICALWHITE PL-1 imparts a lightfast brightness with good textile fastness properties to both PVC and acetate fibers . it has good effect on PP, PE, PU and Nylon-6.

STORAGE :

OPTICALWHITE PL-1 should be stored in a cool, dry area. Extended storage at elevated temperatures or exposure to direct heat or sunlight could reduce product life. Keep Container sealed not in use.
