Informações Resistência Química
Our Chemical Resistance Database provides you information on chemicals and fluids known to attack or be compatible with the Quadrant materials listed.
For our database, please consider the information given as a guideline. For more specific information please contact us.
Quadrant Engineering Plastics - Chemical Resistance Database
A : Resistant. Little or no change in weight. Small effect on mechanical properties. Generally suitable for practical use.
B : Partially resistant. In course of time, there is a distinct deterioration in mechanical properties and a change in weight. In many cases a short exposure may be considered allowable.
C : Non-resistant. After a short time, the material is seriously affected (considerable reduction of the mechanical strength and changes in weight). Using the material under these conditions is not recommended.
O : The plastics material dissolves in the chemical.
A number, e.g. 20, indicates “20 g of solute per 100 g of aqueous solution” (20 % by weight).
UD : Undiluted (technically pure chemical)
SS : Saturated aqueous solution (at 23°C)
CA : As commercially available
RT : Room temperature (15 – 25 °C).
* The resistance ratings given for Ertalon®/Nylatron® and Ketron® PEEK are in first instance valid for the unreinforced grades. As far as the glass fibre reinforced grades are concerned (Ertalon® 66-GF30 and Ketron® PEEK GF-30), it has to be noted that they are more affected by hot aqueous solutions than the unreinforced grades. Therefore, preliminary testing under actual service conditions is strongly recommended.
The ratings given here, derived from raw material supplier data and from literature related to the chemical resistance of plastics, are intended as a guide only and not as an alternative to actual testing. Therefore in practice, it is strongly recommended to carry out preliminary tests on a prototype under actual service conditions, to evaluate the final suitability of the selected plastics material for your application.
