Material Selection & Construction Methods
Modern fiberglass-reinforced plastics are characterized by a very low maintenance effort in applications subject to corrosion. The following materials and construction methods are mainly used by plasto-tec:
► Fiberglass-reinforced plastics with chemical protection layer
► GRP in combination with thermoplastic liners (PVC, C-PVC, PE, PP)
► GRP in combination with partially fluorinated liners (PVDF, E-CTFE)
► GRP in combination with fully fluorinated liners (FEP, PFA, M-PTFE)
Specialist for Composite Constructions
As early as 1952, Plasticon began to supply the chemical industry with composite components. The outstanding chemical resistance of thermoplastics and fluoroplastics is combined with the mechanical strength of GRP.
The liner is produced by welding and thermoforming. Starting with an adhesion-promoting intermediate layer, the load-bearing GRP laminate is built in layers. The higher costs for these high-quality composite components are generally justified by a prolonged service life, lower maintenance costs and / or a more efficient production process.
Composite constructions are increasingly being specified by our customers for applications whose operating conditions place high demands on chemical resistance and mechanical strength.
Liner selection (thermoplastic, partially and fully fluorinated).
► PVC (max. 70° C)
► PE (max. 85° C)
► PP (max. 90° C)
► C-PVC (max. 85°)
► PVDF (max. 120° C)
► E-CTFE (max. 130° C)
► FEP (max. 140° C)
► PFA-M (max. 160° C)
► M-PTFE (max. 160° C)
► PFA (max. 260° C)
Based on fully fluorinated semifinished products, foil linings are part of the standard, either clamped as loose shirts between flanges or fixed to the load-bearing wall, but also as a suspended apron to protect particularly stressed GRP areas. The following temperature limits apply to foil linings: PFA (260° C).
