Composite materials - Import export

Riga Poliform Birch plywood ( Riga Ply) overlaid with a special composite material on both faces. Overlay colour The standard color is grey. Application Formwork systems. Advantages This product produces a superior appearance to the concrete surface whilst protecting the plywood substrate. The expected lifetime of the panels, when properly used, may exceed 100 times. The thickness of the composite face material helps to protect the plywood against swelling. The composite material is ecologically safe and recyclable. Overlay The composite material is made of wood fibres and polypropylene. The overlay is glued with D3 or D4 class glues according to the standard EN 204 requirements. The thickness of the overlay is 1.6 mm. The surface is glossy or mat. The surface of this material resists well against various kinds of damages. After use, the panels release well and maintain their performance for a long time. Moisture absorption inferior to 1.8% translates to excellent weather resistance. The UV-resistance of the HPL-overlay is from average to good. The panels can be used within a temperature range from -40°C up to +80°C. Sizes 1220 mm x 2440 / 3050 mm 1250 mm x 2500 / 3000 mm 1500 mm x 2500 / 3000 mm 1525 mm x 2440 / 3050 mm Cut-to-size panels are available in accordance with customers’ requirements. Thicknesses 9, 12, 15, 18, 21, 24 mm.

Testing machines for torsion testing are mainly used in science, research and teaching, in testing laboratories and in production control during production.They are used to determine the torque load of specimens made of different materials in static tests, e.g: Plastics, composite materials Screws, cardan shafts Twisting tests on wires according to DIN ISO 7800 and ASTM A938 as well as alternating twisting tests on wires according to DIN ISO 9649 Calibration of torque sensors
