From mass-produced to high-performance: plastics optimized by radiation crosslinking
Radiation crosslinking gives inexpensive commodity plastics and technical plastics the mechanical, thermal and chemical properties of high-performance plastics. This upgrading of the plastics enables them to be used in conditions which they would not be able to withstand otherwise.
The energy-rich beta or gamma rays trigger chemical reactions in the plastics which result in a ‘crosslinking’ reaction of the molecules – forming a network comparable to the vulcanization of rubbers, which has been in industrial use for so long.

Since it is the finished plastic product which is modified in this way, it is even possible to vary the degree of crosslinking within one component by shielding parts of the product during irradiation. In this way BGS helps you to optimize the material properties of plastics, and opens up new application fields for established raw materials.

Process at room temperature, normal pressure
The process takes place at room temperature and under normal pressure
Advantages of thermoplastic and thermosets combined
Irradiation takes place after the moulding process. In this way, the processing advantages of thermoplastics are combined with the properties of thermosets
Flexible parameters
Parameters can be flexibly adapted to individual requirements in each case
Substancial cost savings
Substantial cost savings from the use of relatively inexpensive commodity and engineering plastics. It is not generally necessary to invest in new injection moulding tools
No admixture of crosslinking chemicals
The admixture of crosslinking chemicals such as peroxides is no longer necessary. This cuts material costs, and brings benefits for reproducibility and processing. For instance, without the need for in-line crosslinking, extrusion times for PE pipes are three to four times faster
No impact on process speed
Because crosslinking takes place as an external step after the manufacturer’s production process, optimal process speed is not affected. Another advantage of irradiating the finished injection moulded parts is that plastic production waste (for instance mould gate residues) can simply be returned to the production process.
Suitable for combination of materials
Radiation crosslinking is also suitable for combinations of materials; even metals in combination with polymers can be irradiated
