Material Selection

Primarily, the mechanical, thermal and chemical loads the construction material must withstand determine the choice of materials. However, cost-effectiveness considerations such as over-all maintenance costs, including downtime-costs, must also be taken into account.

Plasto-tec GmbH supplies plant components manufactured out of a wide range of plastics: From straight thermoplastics such as PE or PVC to modern glass-fiber reinforced thermosets with integrated chemical protection layer.

Specialist in Composites

Composite materials combine the respective advantages of thermoplastics and glass fiber reinforced thermosets (GRP). Already since 1952, Plasticon supplies the chemical and other industries with such components. The excellent chemical resistance of thermoplastics and fluoroplastics is combined with the mechanical strength of GRP. First of all, the so-called liner is manufactured out of thermoplastics by welding and thermoforming. This structure provides excellent chemical resistance, but cannot cope with the mechanical strength required. Thus, the load-bearing GRP laminate is assembled layer by layer on this liner. An adhesive intermediate layer is responsible for combining the two materials adequately. Although the production efforts are significantly higher for such high-quality composite components, they pay off in general: The service life of such components is extended, consequently downtimes and maintenance costs are reduced and the hours of continuous operation increased. Thus, the over-all efficiency of production improves.

► Thermoplastic plastics (PE, PP, PVC)
► Fiberglass-reinforced plastics (GRP) with chemical protective layer (CSS)
► GRP in combination with thermoplastic liners made of PVC, C-PVC, PE, PP
► GRP in combination with partially fluorinated liners made of PVDF, E-CTFE
► GRP in combination with fully fluorinated liners made of FEP, PFA, M-PTFE


Sheet Linings

Based on fully fluorinated semi-finished products, loose linings are now state-of-the-art. They are either clamped between flanges as a so-called “loose shirt” or mounted via fixed points on the load-bearing wall. For the protection of particularly stressed areas, they are also carried out as a “suspended liner”. The temperature limit for such linings is currently 260°C (requires the use of PFA).
