 Product DescriptionAlthough the Hot Plate Film Shrinkage Apparatus is not controlled by any International test standards, it is still a very widely used apparatus, providing information sufficient for most quality control procedures. Where precise results are essential, the Ray-Ran Unrestrained Linear Thermal Film Shrinkage Apparatus should be used. The principal of both the hot plate and the immersion methods are the same, notably to determine the amount of shrinkage of a film when heated to release the internal stresses produced due to the manufacturing methods. The hot plate method is very simple and quick to understand. A film sample of round or rectangular shape is placed on a hot plate maintained at a constant temperature, and with its surface lightly oiled with Silicone oil to ensure good heat transfer from the hot plate to the film. A light cover plate which keeps the film flat is placed on the top of the film sample. After a set time the film is re-measured and its percentage shrinkage determined.
Standard features include
Digital temperature display and control, Test sample template, Test sample cover lid, Small bottle of Silicone oil, Product user manual, CE mark of conformity, 1 year return to base warranty
Optional Accessories include
50mm dia Test Sample Cutter, Hand operated Cutting Press.
Test DescriptionA Test Sample of the material is cut and its orientation with respect to the manufacturing process marked. It is then lightly coated with Silicone Oil and placed on the Hot Plate for the required time, after which its measured and the shrinkage determined.
