Polymere cleaning technology

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

Use of
1
Plastics with abrasive fillers
2
Corrosive vapors
3
Plastics with high melting temperatures
4
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 tometal 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.

purging material

solid ready mix purging compound

Professional program, flexible, quick

Our Purging Material is a non-corrosive, non-abrasive purging compound that performs by means of mechanical forces released from high viscosity polymers as well as scrubbing minerals and blowing agents. The blowing agents increase the pressure inside the barrel and allow the high viscosity polymers and the scrubbing minerals to reach all the “dead spots” inside the cylinder, the nozzle and the hot runner and therefore releasing all the residual polymers pigments and other contaminants.

Purging Solution

Today purging is not anymore only a way to clean and maintain the equipment. It is also a solution for an efficient cost saving as well as a controlled production process.
