POTICON
POTICON is a series of plastic compounds utilizing our ultra-fine Potassium Titanate fiber, TISMO. POTICON is used in a wide variety of applications including micro-reinforcement applications, such as LED reflectors and camera modules, as well as sliding parts, particularly in the demanding automotive industry.
Advantages
Microscopic Reinforcement:
Length(10 ~ 20μm) of TISMO is nearly equal to the diameter (about 10μm) of other reinforcing fibers. This helps to enhance the strength of precision components such as watch gears and camera modules.

Excellent Abrasion Properties:
Hardness of TISMO is lower than that of other reinforcing fibers.
Using fibers of microscopic size, the surface of molded parts is smoother than using Glass or Carbon fibers.
These characteristic features helps to reduce friction and improve wear durability.
