CHEMICAL

Engineering plastics have been implemented in the chemical industry as a material for tanks and plants for many decades now.Polypropylene PP sheet is commonly used in the chemical and food industry. Polypropylene fabricates with standard woodworking tools and can be welded. This makes polypropylene excellent for plating tanks, acid baths and a variety of food containment applications.

  • Chemical, corrosion and rust resistance
  • High strength, light weight, maintenance free
  • Good impact and abrasion resistance
  • Hygienic
  • Enduring Integrity
  • Versatility to suit individual needs
  • Low cost fabrications
  • Dimensionally stable
  • Excellent electrical properties
  • Weldable and formable

Common applications of plastics:

Tanks for storing liquids: Plastics fulfil varying demands in chemical-tank and plant construction ranging from resistance to thermal and chemical corrosion as well as static loading and depending on the set-up – resistance to weathering influences. Round shaped and rectangular shaped tanks are manufactured using sheets in a strip winding process or as a composite tank.

Galvanic plants: In galvanic plants, items are provided with a metallic coating in an electrochemical process in order to increase their corrosion resistance. Also falling under the category of galvanic technique or electroplating are such processes as chrome-plating machine parts, zinc-coating nuts and bolts as well as anodic oxidation of aluminium parts (anodisation). Due to the diversity of these chemical processes, various plastics are used in galvanic plants.

Steel-pickling plants: In the pickling process, cold-rolled steel bands are rid of the scaling incurred on the surface by the hot-rolling process. In the past decade, application of polypropylenes in pickling tanks has been time tested and is ever increasingly substituting rubberised or brick lined steel tanks.

Water-treatment plants: Grades of engineering plastics which have a high degree of purity and are particularly chemical-resistant are used to fulfil matching to the current standards of hygiene.

Exhaust-air cleaning plants: In order to minimise damage to health and the environment through air-borne pollutants, droplet separators and gas scrubbers manufactured using engineering plastics are used to restrict the pollutant loads in emissions, because of their corrosion resistance.

Ventilation plants: Removal of polluted air is an important challenge in buildings and chemical plants. Both ventilator constructions as well as provision of air ventilation ducts and housings for plant parts are included in the field of ventilation plants. Engineering plastics are used as an in liner for ducts made of glass-fibre-reinforced plastics. Should the static, thermal and chemical load permit, complete parts can be made of these materials. Often special requirements are also made on the materials used in ventilation plants with regard to electrical conductivity and low inflammability.
