SUMIKASUPER LCP is a thermotropic liquid crystalline polyester that possesses the highest heat resistance among all engineering plastics.
Its basic chemical composition is shown in the diagram below. Thermotropic liquid crystalline polyester is one of the most common types of liquid crystalline polymer.

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.
