Why should fluorescent brighteners be added to acrylic materials

 Acrylic is a kind of plexiglass, which is an important plastic polymer material developed earlier. It has good transparency, chemical stability and weather resistance, easy dyeing, easy processing and beautiful appearance, and is widely used in the construction industry. Plexiglass can usually be divided into pouring plate, extrusion plate and molding. It has the advantages of light weight, low price and easy molding.

Its molding methods include casting, injection molding, especially injection molding, which can be produced in large quantities, with simple process and low cost. Therefore, it is widely used in instrument parts, automobile lights, optical lenses, transparent pipes and so on.

However, many people encounter problems such as yellowing, insufficient whiteness and poor weather resistance when producing acrylic boards, but they don't know whether acrylic fluorescent brighteners should be added. Let's tell you why fluorescent brighteners should be added to acrylic materials.

The problems encountered in the production of acrylic board are mainly yellowing, fading and low transparency. Generally speaking, these problems are all about color and light. Yellowing is due to more yellow light reflected by acrylic board. If enough blue light is added, yellow light can be neutralized. Transparency can also be improved by supplementing light and increasing brightness.

The fluorescent whitening agent absorbs ultraviolet rays and emits blue-violet light, which just supplements the missing blue light on the acrylic board, and also increases the total amount of reflected light, making the acrylic board look whiter and brighter.
