SUMIKASUPER LCP
Description
SUMIKASUPER LCP is a thermotropic liquid crystalline polyester that possesses the highest heat resistance among all engineering plastics.
Prosessing:
It is not necessary to dry SUMIKASUPER LCP for a long time, as it has extremely low water absorption of 0.02%. In general, the drying time required is between 4 hours and 24 hours, when a hopper dryer is utilized at a temperature of approximately 130°C. SUMIKASUPER LCP does not require high injection pressures, as it possesses low melt viscosity and high moldability.
Flame Retardancy
SUMIKASUPER LCP possesses excellent flame retardancy without any flame retardant agents. In addition, the gases produced as a result of combustion are mainly carbon dioxide and water.
Electrical Properties
SUMIKASUPER LCP products all possess low, stable values for the dependence of dielectric constant and dielectric dissipation factor on temperature and frequency. However, the absolute values for these properties are higher than those of other engineering plastics (Figure 2.10 and Figure 2.11). In other words, although heat generation tends to be greater at higher frequencies, this does not cause problems during actual usage, due to the extremely high deflection temperature under load. Moreover, the dielectric dissipation factor for liquid crystal polymers is low within the GHz region.
Water Absorption
SUMIKASUPER LCP shows very low water absorption of only 0.02%.As well, even if left in water over extended periods of time, almost no changes in weight or dimensions will be observed.
Chemical Resistance
SUMIKASUPER LCP possesses outstanding chemical resistance and will not expand or deteriorate when exposed to oils, even at high temperatures.
Hot Water Resistance
SUMIKASUPER LCP still demonstrates effective levels of strength, even after 2000 hours of soaking in hot water, at a temperature of 80°C. However, when exposed to steam at temperatures of greater than 120°C, hydrolysis begin to occur,causing large strength degradation and rendering the product unusable.
