replace POLARIS phe gasket S43

Gasketed Plate Heat Exchanger, Plate Heat Exchanger, Plate Heat Exchangers PHE plates/gaskets are non-OEM, 100% compatible with genuine parts.

All PHE Gaskets and Plates are produced under approved production conditions, and both Rubber compounds and Plate material are analyzed on a third-party lab. Entrance material-control for Plates and gaskets is made at our own lab, to ensure compliance with certificates.

NBR has excellent oil resistance. In typical NBR structures, trans accounts for approximately 78%. Because the molecular chain structure of NBR contains cyano group, its oil resistance (such as resistance to mineral oil, liquid fuel, animal and vegetable oils and solvents) is better than that of natural rubber, Neoprene and Styrene-butadiene. Compared with other rubbers, NBR has a wider range of usage temperatures, with a long-term usage temperature of 120 ℃. At the same time, NBR has good low-temperature resistance, with a minimum glass transition temperature of -55 ℃. [1]

NBR has good chemical stability and processing performance. With the increase of acrylonitrile content in its structure, its relative density increases, the vulcanization rate accelerates, and the tensile strength performance improves. However, its rebound performance decreases and its cold resistance deteriorates. Due to the susceptibility of the cyanide group in NBR to electric field polarization, its dielectric properties decrease, making it a semiconductor rubber. NBR can be divided into five categories based on the ACN content: ultra-high, high, medium high, and medium low acrylonitrile. There are two production methods: continuous and intermittent polymerization. The continuous polymerization method is usually used for small variety and high yield production, with low consumption. Intermittent polymerization method is suitable for multi variety and small batch production, with high engineering construction consumption. [1]

Although Nitrile rubber has excellent physical and mechanical properties and processing properties, its long-term use performance in acid gasoline and high temperature (150 ℃) environment is not as good as fluororubber and acrylate rubber. Therefore, hydrogenated Nitrile rubber (HNBR) with excellent performance has been developed. In addition, Nitrile rubber and carboxyl Nitrile rubber (XNBR) with super cold resistance and high purity have also been developed. [1]
