Optical properties of polystyrene

 

The most important characteristic of polystyrene is that it has very good thermal stability and fluidity during melting, so it is easy to form, especially injection molding, and is suitable for mass production. The molding shrinkage rate is small, and the dimensional stability of the molded article is also good.

Polystyrene has excellent optical properties and can transmit visible light of all wavelengths, which is second only to acrylic polymers such as plexiglass. However, due to the poor weather resistance of polystyrene, it may cause turbidity and yellowing due to the action of sunlight and dust during long-term use or storage. Therefore, when using polystyrene to make high transparent products such as optical parts, it is necessary to consider adding appropriate varieties and The amount of anti-aging agent.

We are a chemical company-Leili Chemical Co.,Limited specializing in the production of expanded polystyrene with many years of export experience. We look forward to working with more customers from all over the world and working hard for this goal.
