Polymer modification
We are ideally setup for all type of polymer modification with our tray conveyer which can handle liquid or granular products as same as packed boxes or piece goods.

Polymer Crosslinking
The advantages of crosslinking by using accelerated electrons are the

increase of:

  • tensile and impact load
  • comparative tracking index
  • durability
  • fastness to solvent and chemical
  • abrasion resistance
  • resistance to stress cracking
  • thermal stability and temperature limits

Electron beam crosslinking can be used for all kind of products, for example:

  • granular products
  • tubing on small reels or in pieces up to 2400mm length
  • all kind of packing material, bags and foils
  • bottles, tubes
  • all kind of bottle and bag closures
  • boxes
  • housing for electrical devices
  • automatic circuit breaker
  • plastic parts for automotive industry

Curing of high performance composite products
Electron Beam curing is a non-thermic process to cause the resin to crosslink and therefore produces high performance composite parts. It opens the possibility to build complicated composite structures without the need of autoclaves and expensive, high pressure and temperature resistant moulding tools.

Controlled degradation
For certain materials the electron beam radiation can improve properties by controlled degradation or chain scission.

Nucleation of Polymers by electron beams
During the cooling of the melting of polymers like PA 6, PP, PE, Polyoxymethylene (POM) and Polybutylene Terephthalate (PBT), spherulite structures can form. A slow cooling will produce only a few relatively large spherulites. To enhance some characteristics of these polymers, the formation of many small spherulites is necessary. This can be influenced by using boron nitrid, silicates, metal oxides or metal salts of organic acids. These usually toxic substances are built into the matrix of the polymers which can negatively affect mechanical properties.

By irradiating a part of the granule with electrons, it can be used to influence the nucleation. Toxic substances are no longer necessary. The amount of irradiated granule and the energy dose being used might be different for each polymer. The following enhancements can be achieved by using this method:

  • Thermal stability due to a higher melting point
  • Mechanical strength
  • Creeping
  • No toxic substances necessary
  • Shorter cycle times during injection molding due to faster cooling/ crystallization
  • Specific modification of the melt index

Reducing microorganism contamination
By using electron beam irradiation all type of bacteria, viruses, yeasts, fungi and fungal spores will be eliminated. For objects of art or archaeology the electron beam can be used for disinsection respectively disinfestations as a non-destructive process.
