Only process chemicals that have been tested and approved (e.g. VAH/

DGHM or FDA approval or CE mark) and which are compatible with the

product’s materials according to the chemical manufacturers’

recommendations may be used for processing the product. All process

parameters specified by the chemical’s manufacturer, such as

temperatures, concentrations and exposure times, must be strictly

observed. Failure to do so can result in the following problems:

• optical changes of materials, e.g. fading or discoloration of aluminum.

For aluminum, pH >8 in the application/process solution is sufficient

to cause visible surface changes.

• material damage such as corrosion, cracks, fracturing, premature aging

or swelling.

¾ Do not use process chemicals that cause stress cracking of plastics

such as PPSU, or attack softeners e.g. in silicone and cause brittleness

of the material.

5.2 Cleaning/Disinfecting

CAUTION

Damage to the product due to inappropriate

cleaning/disinfecting agents and/or excessive

temperatures!

¾ Use cleaning and disinfecting agents according

to the manufacturer’s instructions. The cleaning

and disinfecting agent must

- be approved for plastics and high-grade

steel

- not attack softeners (e.g. in silicone).

¾ Observe specifications regarding concentration,

temperature and exposure time.
