Plastics for chemical tanks and plants

The performance capacity of chemical tanks and plants is determined by many factors. High operating safety is required even at aggressive chemical media, high thermal and static stress. Constructors need materials specifically suitable for such requirements. Our plastics have been in use in the chemical industry for more than 50 years. They are particularly chemicals-resilient, heat-resilient and easy to process. Around the world, they help constructors build low-maintenance tanks and facilities with a high process safety.

Tried and tested applications of our plastics in the chemical processing industry include:

Secure join – what matters when welding

The welded seam plays a crucial role for the operational safety and service life of tanks. In order to ensure weldability, regular tests are carried out on welded joints in our development centre. This allows us to ensure the highest quality of existing materials while simultaneously incorporating its expertise into the development of new materials. But how can the suitability of materials for welding actually be tested and what tests are used to check the quality of welded joints?Read more about the weldability of plastics

Tests for dual laminate constructions

Special requirements as to the strength and dimensioning of tanks can require a laminate of various materials such as thermoplastic and composites. A very high bond strength is required to ensure that tanks with this dual laminate construction have high operational security. Measurements to assess whether materials are suitable for this are the interlaminary shear strength and the tear resistance. Both tests are described in the DIN EN 13121-3.
