Maxar Red, one of several lines of dual laminate piping available from RPS Composites, is now manufactured using Kynar Flex PVDF as the corrosion barrier layer. Kynar Flex PVDF copolymer is designed for increased chemical resistance in the pH range of <<1 up to 13.5. Kynar Flex has higher tensile elongation than traditional PVDF materials leading to ductility at ambient and colder temperatures and allowing for easier assembly and flaring. The material has a UL RTI rating of 130℃ and is a strong barrier against permeation of acids, chlorine and bromine at lower temperatures.
Suggested applications for Maxar Red piping include hot strong acids such as benzoic, chromic, citric, fatty olefin, fluorosilicic, hydrobromic, hydrochloric, hydrofluoric, methane sulfonic, nitric, phosphoric, salicylic and sulfuric. Other applications include brine, brominated solutions, chlorinated solutions, aliphatic and aromatic hydrocarbons and wastewater mixtures of these chemicals. Kynar and Kynar Flex PVDF materials are also highly abrasion resistant thermoplastics, making them useful for applications with slurries or other abrasive media.
In acidic environments, the performance of a non-metallic is a real advantage. RPS Maxar Red offers longer life, less maintenance, no venting or collection systems and more assembly options than lined steel. By replacing unnecessary flanges with shop or field joints, the fully bonded, seamless Maxar Red is less expensive and more dependable than lined steel.
