Properties and Behaviour
Hearing these words, you first think of the materials our clothing is made of. But all objects surrounding us in everyday life consist of one or several materials. They are objects that are made, for example, of metal, wood, rubber, plastic. In chemistry these objects are also called ‘solids‘.

Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines.
