Πίνακας Χημικής Συμβατότητας

R : Resistant

nr : Not Resistant

L : Limited resistance (possible inflating / crystallizing action)

T(°C)/L : Limited resistance / maximum working temperature of T(°C)

T(°C) : Chemical agent tested up to temperature T(°C)

– : Chemical not tested

O : Resistant (on PTFE/FEP/PFA products where it’s not been possible

to test all chemicals in the product’s wide working temperatures

range, it has been given only a general resistance to the chemical

without specifying the maximum working temperature when under

the effect of the aggressive agent)

a : In presence of chemicals for this product it’s recommended the

usage of fittings that work on both internal and external diameter.

The usage of automatic push in fittings is not suggested

b : Hydrolysis: only the use of PA continuously over many years with

water at a maximum temperature of 65°C or higher makes

hydrolysis a prevailing degradation mechanism. An aggravating

factor for the hydrolysis process is the presence of acids.
