Corrosion Resistance Test (*2) No corrosion No corrosion No corrosion
(*1) The test procedure for cross-cut adhesion is as follows: Using a safety razor, create a mesh of intersecting cuts (the shape of lines on a Checker board) into a base material that has been coated with SUMIKAEXCEL 5003P. The cuts must be deep enough to reach the base material and should be spaced 1 mm apart, to form a series of 1 mm x 1 mm squares, over an area of 100 mm2. Place adhesive tape over the area of the cuts and apply pressure, then remove the tape. Check the squares to determine the number of squares that still contain the PES coating.
(*2) The test procedure for corrosion resistance is as follows: Place several drops of a solution containing 15% (vol) nitric acid onto the test surface that has been coated with SUMIKAEXCEL 5003P. Cover the surface with a glass plate and let it stand for 24 hours. Observe any changes in the surface appearance.

(Note) 1)G1c values were measured under flat surface distortion conditions at -65°C.
2) Tg values were measured using torsion DMA.
The table above indicates a large increase in fracture toughness (G1c). It is also apparent that Tg does not decrease as significantly.

Applications for Membranes
High molecular weight grades of PES 4800P, 5200P and 7600P are utilized mainly in applications as membranes. The remarkable features of polyethersulfone membranes include: excellent heat and chemical resistance, and compatibility with the majority of sterilization methods.
The features and applications of PES are described below, using examples.
Example 1. Polyethersulfone UF Membranes
Features
¡Ü Polyethersulfone UF membranes are suitable for repetitive heat sterilization, as is required in order to maintain stringent sanitary conditions for applications within the food and pharmaceutical industries, and for fermentation processes.
¡Ü Polyethersulfone UF membranes can be utilized over a wide range of pH values, from pH 1 - 14. They also have excellent resistance to chemicals and can withstand strong cleaning agents, thus facilitating easy recovery of membrane performance.
Applications
Manufacturing Processes for Medicinal Preparations
¡Ü Manufacture of biogen-free water and sterile water
¡Ü Concentration and desalination of protein and enzyme preparations
Fermentation and Brewing Processes
¡Ü Concentration and recovery of yeasts and fermentation microbes
¡Ü Refining of fermented products
¡Ü Sedimentation prevention for fermented and brewed products
Food Manufacturing Processes
¡Ü Recovery and refining of usable substances
¡Ü Separation and refining of usable products
