Acid-resistant mortar consisting of epoxy resin, siliceous aggregates (col-ored quartz sands), a mix-ture of organic catalysts (polyamide ammines), and a liquid additive (di-isopropilnaftalen).
Thermoplastic poly-urethane (TPU) with shape-memory (SMP) properties. When the TPU is deformed the printed QR code(quick response) is unreadable but due to the nature of the SMP, the material will revert to its original form when heated.
Paper loaded with ceramic (Al2O3, alumi-num oxide) particles integrated within the wood pulp fiber layers.This semi-finished ceramic material offers cost reduction, a smooth surface, with uniform wall thickness and cus-tomizable porosity.
