Section 3 Specification & Performance MECHANICAL PROPERTIES The mechanical behaviour of Marpet FS PET is characterised especially by its modulus of elasticity and impact resistance. The modulus of elasticity is a measure of the rigidity or elasticity of a material. It denotes the relationship between the force exerted on the sheet in the tensile test and the resulting elasticity. The modulus of elasticity depends on the test conditions and temperature. Luminous beam Reflection Total transmission Direct light transmission Surface scattering Haze At room temperature elastic modulus is around 2400...

Section 3 Specification & Performance CHEMICAL RESISTANCE Chemicals can affect the strength, flexibility, surface appearance, colour, dimensions or weight of plastics. The basic modes of interaction which cause these changes are: • chemical attack on the polymer chain, with resultant reduction in physical properties • physical change, including absorption of solvents, resulting in softening and swelling of the plastic; • stress cracking from the interaction of an incompatible chemical. Other factors affecting chemical resistance include pressure and internal or external stresses, length of exposure,...

Fabrication GENERAL GUIDANCE Tools Marpet-a FS and Marpet-g FS sheets may be machined using standard tools used for metal and woodworking. Carbide-tipped tools are recommended. It is important to use sharp cutting tools with the correct angles. Cooling Cooling is not necessary during the normal machining of Marpet-a FS and Marpet-g FS sheets. If overheating does occur during machining the area should be cooled with water or compressed air. The use of oil emulsions and cutting oils is not recommended as these may contain chemicals to which aPET and PETg are not resistant and could result in stress...

Hand saws A standard hand saw with fine spacing between the teeth may be used to cut Marpet-a FS and Marpet-g FS sheets. When sawing by hand it is likewise better to use blades that are narrower and have more set. Circular saws A circular saw is the easiest way to cut Marpet-a FS and Marpet-g FS sheets. Carbide-tipped circular saw blades produce the cleanest cuts. The tooth pitch of the blade varies depending on sheet thickness (fine for thin sheets, too coarse for thicker materials). Remove swarf and shavings from the cutting surface to avoid potential damage to the protective film and sheets....

HINGE EFFECT Standard metal working drills are suitable for machining Marpet-a FS and Marpet-g FS. Ensure the drill bits are sharp. Cooling during drilling is generally not necessary. For large drilling depths use water or compressed air and/or regularly withdraw the drill from the hole to reduce heat and remove shavings. Marpet-a FS has a very high level of fatigue resistance, creating scope for a diverse range of hinge effects. By pressing with a blunt blade, pre-punching or milling, it is possible to create the bent edges that may be required on the inside. Sheets of up to 1.5 mm in thickness...
