Overview of 4,4-Bis 2-Benzoxazolyl Stilbene

4,4-Bis(2-Benzoxazolyl) Stilbene is a benzoxazole-based fluorescent brightening agent widely known as Optical Brightener OB-1. Its CAS number is 1533-45-5, molecular formula is C28H18N2O2.

It absorbs ultraviolet light and emits blue fluorescence, helping reduce the visible yellow tone of suitable polymers and improve perceived whiteness and brightness. This makes it particularly useful in plastics and fibre applications where improved visual appearance is required.

OB-1 is valued for its strong whitening effect, good lightfastness, and high-temperature resistance, making it suitable for polymer-processing environments where heat stability is important.

The 4,4-Bis(2-Benzoxazolyl) Stilbene price depends on purity, grade, quantity, packing, market availability, freight, and delivery destination.

Applications of 4,4-Bis 2-Benzoxazolyl Stilbene

Plastic Manufacturing

4,4-Bis 2-Benzoxazolyl Stilbene is widely used in plastic processing to improve brightness and reduce yellowish appearance in finished polymer products.

It is especially relevant in applications where manufacturers want a cleaner, brighter visual finish without changing the base polymer colour significantly.

Polypropylene Products

4,4-Bis(2-Benzoxazolyl) Stilbene can be used in polypropylene films and other PP-based materials as an optical brightening additive.

Polymer processors should select dosage according to resin type, colour target, processing temperature, and finished-product requirements.

Polyester Fibres

4,4-Bis 2-Benzoxazolyl Stilbene is used as a fluorescent brightener in polyester fibre applications where high brightness and whitening performance are desired.

Its heat resistance makes it suitable for selected high-temperature polymer and fibre-processing conditions.

Recycled Plastics

Optical brighteners can help compensate for yellowing or dull appearance in recycled polymer materials by increasing visible blue fluorescence.

This makes 4,4-Bis 2-Benzoxazolyl Stilbene useful in recycled plastics where manufacturers want to improve product appearance and perceived whiteness.

Masterbatch Manufacturing

Masterbatch producers may use 4,4-Bis 2-Benzoxazolyl Stilbene in whitening or brightness-enhancing additive concentrates for plastic processing.

The required concentration should be selected according to polymer compatibility, final dosage, colour target, and processing method.

PVC and Coating Applications

4,4-Bis 2-Benzoxazolyl Stilbene may also be used in selected PVC coating and fluorescent material applications where optical brightening or fluorescence is required.
