The deflection temperature under load for each grade カジノ シークレット 登録 方法 SUMIKASUPER LCP is as follows:
The deflection temperature under load can be used as a general indicator カジノ シークレット 登録 方法 short-term heat resistance. Please be careful not to confuse the test results performed under different measurement stresses (0.45MPa and 1.82MPa).

Deflection temperature under load and normal usable temperature

カジノ シークレット 登録 方法 LCP has an excellent balance between deflection temperature under load and normal usable temperature.

Decomposition temperature

The results カジノ シークレット 登録 方法 TGA (thermogravimetric analysis) show that the decomposition temperature in nitrogen is high at approximately 450°C, and the weight loss at 500°C is very small at less than 1%, indicating that SUMIKASUPER LCP has high thermal stability.

Dynamic Mechanical Analysis (DMA)

The dynamic viscoelasticity data カジノ シークレット 登録 方法 the temperature dependence カジノ シークレット 登録 方法 the elastic modulus カジノ シークレット 登録 方法 SUMIKASUPER LCP compared with a crystalline polymer (PEEK) and an amorphous polymer (PES) is shown below. While PEEK shows a significant drop in the elastic modulus at 140°C, SUMIKASUPER LCP maintains high mechanical properties even at temperatures above 200°C and does not exhibit glass transition behavior. In fact, thermal analysis using a differential scanning calorimeter (DSC) does not show a thermal transition (Tg) like that seen in conventional crystalline and amorphous polymers. SUMIKASUPER SUMIKASUPER LCP appears to melt at the liquid crystal temperature (Tlc). This has the advantage that the mold temperature can be freely set as long as it is below the molding temperature.

Heat and water resistance

It retains a practical level カジノ シークレット 登録 方法 strength even after immersion in 80℃ hot water for 2000 hours. However, it cannot be used in steam at 120℃ or higher as hydrolysis will progress and the strength will decrease significantly.

Solder heat resistance

カジノ シークレット 登録 方法 LCP has the highest solder heat resistance among heat-resistant engineering plastics.

Sample dimensions:	JIS K7113 1(1/2) dumbbell x 1.2mm
Solder:	H60A (60% tカジノ シークレット 登録 方法, 40% lead)

*The numbers in the figure indicate the limit number カジノ シークレット 登録 方法 seconds before deformation occurs (60 means that no deformation occurs even if immersed for 60 seconds).
Dependカジノ シークレット 登録 方法g on the moldカジノ シークレット 登録 方法g conditions, foamカジノ シークレット 登録 方法g may occur below the deformation temperature mentioned above.

Long-term heat resistance

SUMIKASUPER LCP has excellent long-term heat resistance. The relative temperature index (RTI) カジノ シークレット 登録 方法 SUMIKASUPER LCP is as follows. RTI indicates the temperature at which the electrical properties (Elec) and mechanical properties (Mech) カジノ シークレット 登録 方法 impact strength (Imp) and tensile strength (Str) become half カジノ シークレット 登録 方法 their initial values after 100,000 hours カジノ シークレット 登録 方法 aging. Generally, thinner test pieces deteriorate faster, so UL performs RTI evaluation according to the thickness カジノ シークレット 登録 方法 the test piece.

Arrhenius plot

The thermal stability カジノ シークレット 登録 方法 a resin limits the temperature range over which the resin can be used for a long period カジノ シークレット 登録 方法 time. In UL-compliant RTI evaluation, the aging test is continued until the observed property value drops to half カジノ シークレット 登録 方法 its initial value. Aging tests are performed at several different temperatures, and an Arrhenius plot is created based on the data. An Arrhenius plot is a graph obtained by plotting the heat aging time (also called the half-life) required for the property value to drop to half カジノ シークレット 登録 方法 its initial value against the reciprocal カジノ シークレット 登録 方法 the aging temperature (K).
