The industry has many different operating conditions. Especially when transporting aggressive, acidic media, the robust properties of plastics guarantee operational reliability for many years. A wide variety of plastics in chemical industrial use therefore suit a wide variety of materials, such as Polypropylene, Polyethylene and PVDF.
Polyethylene
Unique features
- Can be used outside
- moisture repellent
- Can be used at temperatures from –30°C to +80°C
About Polyethylene and chemicals
Hard Polyethylene belongs to the group of polyolefins. It is a very strong material with good chemical resistance and electrical insulation. It is resistant to sunlight and other weather influences (black), moisture-repellent and can be used at temperatures from -30°C to +80°C. High-density Polyethylene is ideally suited for making plastic tanks (round, square and rectangular) and collection trays, HDPE is available in the types HDPE 300, HMWPE 300 and UHMWPE 1000. Polyethylene can be welded excellently by means of wire welding, extrusion welding, butt welding, socket welding, electro-socket welding and infrared welding (rill arm).
Polypropylene (pipes)
Unique features
- Excellent chemical resistance
- Can be welded excellently
- Various versions
About Polycarbonate and chemicals
In addition to the chemical resistance of plastics, which ensures a long service life and safety, plastic pipes offer other advantages. Due to the smooth inner wall, the pressure loss in plastic pipes is lower than that of metal pipes. Polypropylene is characterized by a high impact resistance and a high temperature range. These properties, combined with the exceptional chemical resistance, mean that PP is widely used in the chemical industry. In addition to tanks and receptacles, it is also extremely suitable for dosing cabinets and filling cabinets.
ECTFE
Unique features
- Excellent chemical resistance
- Good diffusion resistance
- Wide working temperature range
About ECTFE and chemicals
The biggest advantage of ECTFE is not only the good diffusion resistance or the wide working temperature range (up to a maximum of 140 °C), ECTFE also has excellent chemical resistance against most organic and inorganic chemicals (pH value 0 to 14) and solvents (max. 120 ° C). In addition, ECTFE has excellent resistance to various acids with a high concentration such as sulfuric acid (98%), hydrochloric acid (37%), nitric acid (100%), caustic soda (50%) and also chlorine compounds such as chlorine dioxide or sodium hypochlorite. ECTFE can be welded excellently by means of wire welding, extrusion welding, butt welding, socket welding and infrared welding (less and creased).
