kemikaalikestävän

Kemikaalikestävän is a Finnish term that translates to "chemical resistance" or "chemical durability" in English. It refers to the ability of a material or substance to withstand degradation or damage when exposed to chemicals. This property is crucial in many applications where materials come into contact with various solvents, acids, bases, or other corrosive substances.

The degree of chemical resistance varies significantly between different materials. For example, certain plastics like PTFE (polytetrafluoroethylene) are known for their exceptional chemical resistance, making them suitable for use in aggressive chemical environments. Metals can also exhibit chemical resistance, often through the formation of protective oxide layers, though they can be susceptible to corrosion by specific chemicals. In contrast, some organic materials may readily degrade or dissolve when exposed to certain chemicals.

Assessing chemical resistance typically involves exposing a material to specific chemicals under controlled conditions and observing changes in its physical and chemical properties. These changes can include swelling, discoloration, loss of mechanical strength, or complete dissolution. Understanding a material's chemical resistance is essential for selecting appropriate materials for manufacturing, construction, and laboratory equipment, ensuring longevity and safety in applications involving chemical exposure. This property is a key factor in determining the suitability of materials for products such as protective clothing, laboratory glassware, seals, gaskets, and chemical storage containers.
