Optical Brightener Ob-1 China Manufacturer CAS No. 1533-45-5

Optical brightener OB-1 is a heat resistant and chemically stable fluorescent whitener that increases whiteness and provides brighter looking colors. It is used to offset the yellowness of a polymer and to yield a whiter appearance. Optical brighteners create brilliance by a fluorescence process involving absorption of invisible UV light and emission of visible blue light. Optical brightener OB-1 is especially useful in polyester and nylon fibers, as well as in high temperature engineering plastics

Optical brightener OB is recommended to increase the whiteness of polyester and polyamide fibers as well as high temperature engineering plastics, including polycarbonates, polyesters, and polyamides (nylon). The product can also be used in styrenic and acrylic polymers.

What is Optical brightener OB-1?

Optical brightener OB-1, also known as fluorescent brightener 393, is a type of chemical compound that is used as a brightening agent in various industries, such as textiles, plastics, and paper. It works by absorbing ultraviolet light and emitting blue light, which makes the material appear brighter and whiter. OB-1 is often used in the manufacturing of plastic products, such as PVC pipes and packaging materials, to improve their appearance.

How does Optical brightener OB-1work?

Optical Brightener OB-1 is a fluorescent whitening agent that works by absorbing invisible UV light and re-emitting it as visible blue light. When added to materials, such as plastics, OB-1 molecules penetrate the material's surface and attach themselves to the fibers. When exposed to UV light, the OB-1 molecules absorb the UV light and transform it into visible blue light, which gives the material a brighter and whiter appearance.

OB-1 works by converting UV rays into blue light, which has a shorter wavelength and is visible to the human eye. The blue light enhances the material's brightness and whiteness, making it appear more vibrant and attractive. Optical Brightener OB-1 is highly effective in enhancing the brightness of materials and is widely used in many industries, including textile and plastic manufacture.

What is the advantage of Optical brightener OB-1?

Enhances brightness: Optical brightener OB-1 is a highly effective brightening agent that can significantly improve the brightness and whiteness of materials, making them appear more vibrant and attractive.

Cost-effective: Optical brightener OB-1 is a cost-effective solution for achieving brighter and whiter materials, as only a small amount of the compound is needed to achieve the desired effect.

Stable and durable: Optical brightener OB-1 is a stable and durable compound that can withstand various environmental conditions, such as high temperatures and exposure to UV light.

Versatile: Optical brightener OB-1 can be used in a wide range of materials, including all kinds of plastics, making it a versatile solution for achieving brighter and whiter materials.

Non-toxic: OB-1 is a non-toxic compound that is safe to use in various applications, including food packaging materials
