A premium product demands top quality starting materials! We construct products you can count on, every time. We are aware of the responsibility that comes with meeting your expectations. Therefore, we expect the same standards for the starting material of our work as for the finished product. That’s why we trust in our long-standing suppliers, whose materials have proven their quality for many years. Instead of wasting time searching for the cheapest starting material, we spend our time constructing a perfect product. Preferred Materials: PE: Polyethylene is by far the most commonly used plastic type worldwide. It is mainly used in packaging materials. PE has a high chemical resistance and good electrical insulation properties. However, its mechanical properties are restricted. Polyethylene is therefore suitable for all parts that are not subjected to mechanical stress or exposed to heat. For our products we prefer the more stable HDPE (high density polyethylene), which is characterized by a small number of branchings in the CH2-chains. This leads to a higher density resulting in a higher stability. PE as well as HDPE is recyclable. We use HDPE for filter housings, tanks, trickling filters and the aerator NEWBUBBLE. PA: Polyamides is a group of plastics with a various characteristics. In general they have an excellent strength and rigidity, are easy to process, and are quite resistant to chemicals. We therefore use PA for our filter housings. However, PA is sensitive to acids. Recycling is possible. PVC: Polyvinyl chloride has good resistance to chemicals, excellent durability, and low flammability. Because of its hardness, it is often used in flooring and pipes. Since PVC is rather brittle, plasticizer is added. This is important to know, especially when using PVC in food production plants. We only use PVC that doesn't release plasticizers into the environment, especially into the water. Recycling of PVC is possible. We use PVC parts for our ozone reactors, filters and skimmers. PMMA: Polymethylmethacrylate better known as Plexiglas. We use it for all components that have to be transparent, including basins, aquariums, and skimmers. It has high strength and stiffness, excellent scratch resistance, and good workability, although it is relatively expensive. However, it has a low toughness, so it is not suitable for mechanically stressed parts. It is important to note that plexiglass should not be treated with polar cleaning agents, such as esters, ketones, and chlorinated hydrocarbons. PMMA can easily be recycled.
