Lenzburg, Switzerland – April 4, 2012 - A common issue of polymer plates is internal stress. Internal stress can cause the material to deform and hinder machining of parts which require even and smooth surfaces. In some cases, if plates with high internal stresses are exposed to high temperatures, they can even become distorted and affect the performance of the end application. It is therefore an important issue and one we continue the focus on improving.
At Quadrant, all major existing processing techniques are available to convert raw materials into sheets and plates, including extrusion, calendering and compression molding. With the upgraded extrusion-calendering technology, internal stress will be further decreased and a smooth surface quality can be achieved, the results are plain and glossy plates. Smooth surfaces are a necessity where plates are used without further surface processing, e.g. in wet bench or chemical tank applications.
In order to better protect the enhanced surface of calendered PVDF and ECTFE sheets, a film is applied on both sides of the product. The film can be removed easily and is resistant enough to prevent damage and scratches during handling.
In applications which require further machining of the plates, low internal stress means that you can expect virtually no dimensional changes from the drawing to the machined part, improving productivity and reliability of the finished part.
We offer calendered plates of 1 mm to 30 mm, with a maximum width of 1500 mm. Films/thin sheets are also available on rolls.
The investment advances particularly our portfolio of Symalit® fluoropolymer materials and applications as well as our POM and PA range.
