The World's Greatest Heat Resistant Polymer XYDAR®

Liquid crystal polymer "XYDAR®" has outstanding superior heat resistance, thin-wall molding, high strength, high elasticity, dimensional accuracy and others, and the heat resistance is the highest level in the world. At present, demand is drastically increasing in the office equipment field as well as the electrical and electronic fields.
In particular, XYDAR®'s high dimensional accuracy expands the application range to high-precision parts and contributes to miniaturization of equipment and improvement of economic efficiency.

Superior properties that no other resins have

Heat resistance

XYDAR®'s deflection temperature under load is extremely high (240 - 350 °C), and XYDAR® has been used for electronic parts that are exposed to the soldering process and oven parts that are repeatedly exposed to high temperatures.

Flame resistance

XYDAR® is inherently flame resistant. As this flame resistance derives from the polymer backbone, without any flame retardant included, UL V-O certification has been obtained.


XYDAR® has remarkably superior fluidity and can easily mold even complex part shapes and thin-wall moldings. Also XYDAR® generates very little burr and sink and has superior workability.

Superior properties that no other resins have

Low burr

XYDAR® has outstanding superior thin-wall fluidity and responds to ultra-precision molding. Also, as XYDAR® generates almost no burr, a deburring process is unnecessary.

Low outgas

As XYDAR® generates very little outgas, maintenance of a die is significantly reduced and productivity is much improved.

Possible to shorten the molding cycle

As XYDAR®'s solidification speed is remarkably higher than other thermoplastic resins, the molding cycle can be significantly shortened.

Possible to mold at low die temperatures

Unlike ordinary crystalline polymers (PS, PA, PBT, etc.), the die temperature has less influence on the properties of a molding. In the case of normal molding, it is possible to mold at a die temperature of 100°C and below.
