Benefits of Using Plasma EPDM Profile Treatment

Treatment of EPDM rubber

EPDM rubber is commonly used in the automotive industry to make several parts of vehicles including the seals of doors, the trunk, the hood, and the windows. It is also used for other purposes such as temperature controlling because of its insulating properties. Practical uses of EPDM rubber include cold rooms, radiators, garden appliances and electrical insulators, tubes and hoses, washers, solar panels, speakers, and headphones.

EPDM rubber can either be conductive or non-conductive which is why plasma treatment is needed to activate it and to achieve a strong bond between the rubber and the adhesive during the flocking process. It is also needed to wet the rubber in the slip coating stage to obtain the desired properties for adhesion. Plasma treatment is used as a replacement of chemical treatments as chemicals are generally dangerous, low yielding, and high in cost. Read more

Adhesion and plastic surface treatment

The Adhesion problem is common in materials that possess low surface energies. Examples can include High-Density Polyethylene, Polypropylene, EPDM, and Polyethylene etc. With the surface energy ranging anywhere from twenty nine to thirty six Dyne/cm or mN/m (milinewton per meter). Surface treatment of plastic products

Bottles plastic
Recycling and reuse of plastic bottles are very important for the future of the environment

Obtaining a level of adhesion on any materials with low surface energy i.e. Polypropylene or Polyethylene etc. can sometimes become extremely difficult because of their slickness. Thus, this adhesion problem leads to the printed ink rubbing off, coatings or paint not sticking on the surface along with failed gluing and weak sealing.

Sometimes it is important to treat various different plastic surfaces. Therefore you should always look for the best solution.

In our opinion, there is a need to look for something that:

  • Is green (Greentech/green technology)
  • Presents ROI (Return on Investment)
  • Can be customized

Surface Treatment for Better Adhesion

Before and after Surface Treatment

Almost each and every surface open to the elements existing in the ordinary atmosphere goes through water and gas absorption within the molecular bounds. Oxidation processes can also bring about a change in surface conditions. Since exposure leads to the gathering of contaminants on a surface, it is imperative that the surface be treated prior to any kind of adhesion. Read more
