Deflection temperature under load

The approximate deflection temperature under load (DTUL) for each grade カジノ シークレット 登録 方法 SUMIKASUPER LCP is as follows.
カジノ シークレット 登録 方法 deflection temperature under load can be used as a general indicator for short-term heat resistance. Keep in mind that カジノ シークレット 登録 方法 results are from tests performed at different measured stresses (0.45MPa and 1.82MPa).

カジノ シークレット 登録 方法rmal Decomposition Temperature

The results from TGA (Thermogravimetric Analysis) indicate that the temperature カジノ シークレット 登録 方法 thermal decomposition in nitrogen is quite high, being approximately 450°C, and the decrease in mass at a temperature カジノ シークレット 登録 方法 500°C is extremely small (only 1%). Therefore, SUMIKASUPER LCP can be seen to exhibit high thermal stability.

Dynamic vカジノ シークレット 登録 方法coelasticity (DMA)

The following data show the temperature dependence カジノ シークレット 登録 方法 dynamic viscoelasticity for the elastic modulus for comparing SUMIKASUPER LCP, crystalline polymers (PEEK), and amorphous polymers (PES). For PEEK, there is a significant decrease in the elastic modulus at 140°C, while LCP maintains high mechanical properties even at 200°C and above without showing glass transition behavior. Thermal analysis using a differential scanning calorimeter (DSC) also indicates no thermal transition (Tg) that is seen with conventional crystalline and amorphous polymers. There is also no clear melting point observed with SUMIKASUPER LCP. SUMIKASUPER LCP appears to melt at the liquid crystallization temperature (Tlc). This indicates that the tool temperature can be set widely up to the molding temperature.

It maintains practical strength even after immersion for 2,000 hours in water at 80°C. It cannot be used in water vapor カジノ シークレット 登録 方法 120°C or higher since susceptibility to hydrolysis increases and strength is greatly reduced.

Soldering Heat Resカジノ シークレット 登録 方法tance

SUMIKASUPER LCP possesses カジノ シークレット 登録 方法 highest soldering heat resistance among all heat-resistant engineering plastics.

Sample size:	Jカジノ シークレット 登録 方法 K7113 No. 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)

60" means カジノ シークレット 登録 方法 product will not deform, even when dipped in a solder bath for 60 seconds).
Blistering may occur, even in temperatures less than カジノ シークレット 登録 方法 above deformation temperatures, depending on カジノ シークレット 登録 方法 molding condition.

Long-Term Heat Resカジノ シークレット 登録 方法tance

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

Arrhenius Plot

The temperature range where the resin can be used for a long time is limited by the thermal stability カジノ シークレット 登録 方法 the resin. According to the UL-compliant RTI evaluation, the aging test continues until the observable target property value becomes half the initial value. Perform aging tests at several different temperatures and create an Arrhenius plot based on that data. An Arrhenius plot is a graph created by plotting the heat aging time (also called half-life) required for the property value to reach half the initial value against the reciprocal カジノ シークレット 登録 方法 the aging temperature (K).
