After the expiry of the The catalyst could also act as a catalyst again be separated from the plastic.
- a polyolefin or ethene-containing is preferred as the plastic Plastic, especially polyethylene or a Olefin polymer or olefin copolymer used, so that results in an elastomer.
- the metallic part of the metallocene can only be titanium or zirconium or a mixture thereof, if it is a Titanocen or Zirkonocen. This results in a particularly good networking with Transition from the monomeric to the polymeric molecular structure or in the chain formation of the molecules.
- Another improvement can be achieved in that the plastic as a molecular Structure instead of a pure polymer, a co-polymer, e.g.
- the weight fraction of the ⁇ -olefin suitably at least 3% and at most 40%, in particular at least 5% and at most 30%.
- the ⁇ -olefin suitably has two to six carbon atoms.
- the plastic is very solvent or chemical resistant and has high softening temperatures, with little extractable components. Furthermore the plastic is odorless and tasteless. He has high shock resistance, good or dense surface quality, a slight thermal distortion as well as a very good stress crack resistance.
- the radiation intensity expediently at least 85 kGy and at most 120 kGy, in particular is about 100 kGy.
- This also enables networking of the molecular chains or the gel portion of the plastic increase.
- the properties mentioned are special significantly improved compared to plastics, which are manufactured with the usual catalyst systems were, for example with so-called Ziegler-Natta or Phillips catalysts.
- Irradiation by an electron beam accelerator o Like.
- All Components of the device 1 are made of plastic, so that they are recycled together can.
- the respective spring is in accordance with Art a coil spring, but the turns of which are not just close together along the helix slope, but also in one piece transversely to each other via connecting sections are connected, the one compared to the spiral pitch have a steeper slope or along the circumference of the spring the axial connections between adjacent spiral sections form. This allows the spring in the manner of a Bellows to be formed.
- the support bodies 32, 41, the valve body 21 or 22, the control piston 33, the counter member 36 and the shaft 65 including the outlet body 52 can consist of the refined plastic.
