It is made for 1/3rd from acrylic substances (methyl methacrylate) and from rock minerals for the remaining 2/3rds. The combination of methyl methacrylate, non-porous, and minerals - homogeneous, durable and stable in time - is the result of sophisticated industrial processes and of a chemical reaction, the so-called polymerisation. This created a material that maintains both components’ characteristics unaltered and preserves the best intrinsic ones. . Avoid direct contact with too hot products, strong acids, solvents, chlorinated solvents or a combination of the latters, and unclogging acidic products. LG HI-MACS is antistatic, non-toxic, hygienic; it does not encourage the growth of bacteria and is inert to mould.
