My Evaglobe Material - EVA PE - Shore 45 Technical characteristics: • Color: White • Dimensions: 1000 x 1000 mm • Thicknesses: 5 mm / 10 mm • Material: EVA (Ethylene-vinyl acetate) and PE (Polyethylene) • Shore A: 45 • Thermoformable: 120°C All your materials may be cut in half without your consent for logistical reasons. Thank you for your understanding. The material sheets come from a block that needs to be cut to obtain them. The slicing generates a "beak" at the entry and a "leak" at the exit. This only affects a small part of the sheet, and the rest can be used. Here is a schematic diagram: A quality control is carried out on each sheet in advance by our teams to ensure that these thickness differences do not exceed a certain threshold. Therefore, the presence of these irregularities being a consequence of the production process cannot in any case be a reason for complaint or return.
