There are many classifications of plastics, and PET plastics are widely used in electronic appliances. For example, switches, electrical sockets, circuit breaker casings and other products, and most of these products are white in appearance.
The appearance of PET plastic is milky white or light yellow, and the surface is smooth and flat. With excellent physical properties, it can still maintain good creep resistance, fatigue resistance and dimensional stability under the environment of temperature up to 120℃. However, because its own whiteness and brightness cannot reach the aesthetic level of consumers, it is necessary to add fluorescent whitening agents and titanium dioxide in the production process to improve its whiteness, so that it has a higher appearance and better weather resistance. .
The types of fluorescent whitening agents suitable for PET plastics are: OB, OB-1, KSN
Fluorescent whitening agent OB, the color light is bright blue light, with good light transmittance; fluorescent whitening agent OB-1 color light is blue light; fluorescent whitening agent KSN, color light is blue-violet light.
