Transparency-Changing Acrylic - Turns opaque when heated
This acrylic plastic (PMMA) changes its transmittance of light and solar radiation as a function of temperature. The transparency changes gradually as the ambient temperature rises from 24°C to 31°C. The change in transparency is reversed completely when the acrylic cools down again.
The acrylic is used as a self-regulating shading material. It is used in skylights, façade elements, canopies, bus shelters, and greenhouses.
The change in transparency has been shown in laboratory tests to work for at least 20 years. The active substance is delivered in a masterbatch that is added to acrylics before extrusion or moulding. Solid sheets, multi-walled sheets, and corrugated sheets are available.
Produce transparency-changing sheets that homeowners can attach to window glass in rooms that get too warm in direct sunlight.
You get a functional moulded sample as seen in the product photo. Put the sample in hot water and watch as the transparency changes.
All samples come with a laminated information card, which includes contact details for the supplier
