Polymers such as PU & latex

Cured polymers such as polyurethane, isocyanate, latex or polyethylene are among the most stubborn contaminants in industry and manufacturing. Eco-Nova offers cleaners for these that are not classified as hazardous according to their safety data sheets, as well as specialist products for removing caked-on residues. We’ll test which one is suitable for you with a free sample.

That’s what it’s all about

Problem and Solution

The challenge

Cured polymers are chemically resistant and are virtually insoluble. Mechanical removal damages moulds and tools, and many effective polymer solvents are classified as hazardous to health. At the same time, every hour spent on cleaning means downtime in production and processing.

Our solution

We assess the type of polymer, the degree of curing and the substrate, and recommend the mildest cleaner that will do the job – such as Nova Safe S, Resinova or Combisolv TR, which are not classified as hazardous according to their safety data sheets. For cured PU residues, there are specialised products such as Purex NF or Purex; these are labelled accordingly and must only be used with the protective equipment specified in the safety data sheet. An example of this can be found in our success story on the removal of polyol and isocyanate from aluminium moulds.

Typical areas of application

  • PU foam and casting systems
  • Mixing heads and dosing systems
  • Moulds and tools
  • Latex and rubber processing
  • Plastics processing machinery

FAQ

Frequently Asked Questions

How do I remove cured PU foam?
Cured PU foam can only be removed using specialised cleaners. The right cleaner depends on the surface and the degree of curing – we test this using a sample.
Are there any polymer cleaners without hazard labelling?
Yes, for example Nova Safe S, Resinova and Combisolv TR – which, according to their safety data sheets, are not classified as hazardous. In some cases, specially labelled products are required for heavily cured residues.
What should you bear in mind when using Purex?
Purex is classified as hazardous to health; amongst other things, it can harm a foetus. It must only be used with the protective equipment and in accordance with the precautions set out in the safety data sheet. We would be happy to check whether an alternative such as Purex NF is suitable for your application.
Can I try out the cleaning products beforehand?
Yes. We provide free samples and, on request, demonstrate how to use them on site.

Effectively remove polymeric deposits

Cured polymeric residues such as polyurethanes, isocyanates or latex are among the most difficult contaminants in industry and production. Thermoplastics such as polyethylene or polypropylene are also difficult to remove - conventional processes quickly reach their limits here.

Risks associated with conventional cleaning

Harsh chemicals or mechanical methods damage materials and are often ineffective. Furthermore, many effective polymer solvents are classified as hazardous to health and require strict safety precautions.

Solution with Eco-Nova industrial cleaners

Eco-Nova offers a comprehensive range of specialised cleaners for cured and polymer residues. Where possible, we recommend cleaners that are not classified as hazardous according to their safety data sheets, such as Nova Safe S, Resinova or Combisolv TR. There are specially labelled products available for particularly stubborn curing residues. We are constantly developing our range in close collaboration with raw material manufacturers.

Areas of application & advice

Whether in plastics processing, machine cleaning or in the construction industry - Eco-Nova provides effective solutions against polymer residues. We would be happy to advise you and provide samples for your application.
