Polymere cleaning technology

Why do metals
corrode at a much
faster rate in the
plastic industry ?

Use of
Plastics with abrasive fillers
Corrosive vapors
Plastics with high melting temperatures
Plastics which give off excessive residues, contaminants, dirt

Six-T7 gmbh maintenance products

These types of compounds can break the passive protective oxide film of stainless steel or even damage a protective coating so that corrosion penetrates.

Local Corrosion can lead to pitting and cause structural damage to metal parts. Once initiated it grows and penetrates from the surface downwards, leading to failure of the structure.

You cannot prevent exposure of steel to such plastics but you can control the corrosion and delay its degrading effect.
