Plastic Chemical Resistance - Chemical Resistance of Engineering Thermoplastics

This Dotmar Plastic Chemical Resistance comparative index should be considered only as roughly indicative. There are too many variables including chemical type, concentration, temperature and contact time. Even the internal stress level of plastic parts can influence the degree of Chemical Resistance and your choice of material.

Inorganic Acids, bases and salts are used in a variety of concentrations, as mixtures, or on their own. For pure solutions and mixtures the pH value of the solution is a reliable tool when assessing the chemical resistance of semi-crystalline plastics.

How are Graphene Batteries Made?

The primary distinction between graphene-based batteries and solid-state batteries lies in the composition of either electrode. Although the cathode is commonly changed, carbon allotropes can also be employed in fabricating anodes.
