As a manufacturer, are you using plastic for the glazed windows in your sectional doors? Then it is likely that you opt for polymethyl methacrylate (PMMA), better known as plexiglass or acrylate. A good choice, but not the best. Because styrene acrylonitrile (SAN) in combination with the right UV- and scratch resistant coating offer more benefits, for both you and the end user.
PMMA is a crystal clear and shiny material. With a brightness of 92% this type of plastic is a logical alternative for layered glass or hard glass. In addition, PMMA sheet material is easy to handle for further processing, like sawing into windows. A relatively good final report marks for the glazing in your sectional doors, you would think. And right you are.
However, there is one major drawback of PMMA: it absorbs a lot of moisture, which makes your windows start warping and optically not tight!
You can avoid this from happening by using a plastic that outscore PMMA: SAN. Styrene acrylonitrile is a highly transparent and thermoplastic plastic.
SAN outperforms PMMA in 4 aspects. It is
In addition, SAN is highly resistant to the impact of UV light and weather condition and therefore very well suited for both indoor and outdoor applications.
Another big advantage: SAN sheet material is very well suited for coating. Coating is a technique in which a thin layer of transparent liquid is applied to the material. Coating improves the mechanical and optical properties, without affecting the other benefits.
In case of SAN, we recommend our UV- and scratch resistant hardcoat UV 1022 Z1. This combination makes SAN even more convenient for glazing in your sectional doors. The optical properties improve and your windows are more resistant to scratches and damage as a result of usage.
