SUMIKAEXCEL PES is a transparent resin with a slightly amber color. It possesses a variety of useful properties, such as heat resistance, creep resistance, dimensional stability, flame resistance and hot water resistance. SUMIKAEXCEL PES is utilized as a molding material in many different applications, including : electronic components, such as relays and burn-in sockets ; IC trays ; printers; photocopier components; sterile medical and dental instruments ; and LCD substrate films for pagers and mobile phones.
In addition, SUMIKAEXCEL PES is also available in powder grades. Powder grades are utilized for a wide range of applications, including: impact modifier for epoxy-based composites used in aircraft ; heat resistant coatings; adhesives; flat films and hollow-fiber membranes used in the medical and other industries.
The DTUL (Deflection Temperature Under Load) for SUMIKAEXCEL PES ranges from 200 - 220 deg C and the UL temperature index designates its continuous service temperature as 180 - 190 deg C.
Its flexural modulus is very stable at temperatures ranging from -100 to +200 deg C. In particular, at temperatures of 100 deg C or greater, SUMIKAEXCEL PES shows the highest flexural modulus among most thermoplastic resins (Figure 1). As well, due to its excellent thermal stability during the molding process, the amount of gas trapped within moldings is much lower than in other engineering plastics (Figure 2).
SUMIKAEXCEL PES possesses a good impact strength. Snap-fit products can be produced with natural grades, however, additional precautions must be observed, as SUMIKAEXCEL PES is susceptible to breakage at sharp notches.
SUMIKAEXCEL PES possesses a high level of light transmittance, outstanding among most heat resistant engineering plastics.
SUMIKAEXCEL PES exhibits both a low coefficient of linear expansion and a low temperature dependence. In particular, the coefficient of linear expansion of grades having high glass fiber content (4101GL30) is 2.3 10-5/deg C. This value is similar to that of aluminum, and is maintained up to nearly 200 deg C.
SUMIKAEXCEL PES has been certified as UL94V-0 (0.43 mm) without any flame retardants. In addition, according to the results of testing conducted by the American National Bureau of Standards, it is commonly understood that, during combustion, SUMIKAEXCEL PES generates the lowest amounts of smoke among all plastics.
