Deflection temperature under load

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

Continuous Service Temperature and DTUL

カジノ シークレット 登録 方法P has an excellent balance between the continuous service temperature and DTUL.

Thermal Decomposition Temperature

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

Dynamic viscoelasticity (DMA)

The following data show the temperature dependence of 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カジノ シークレット 登録 方法, while LCP maintains high mechanical properties even at 200カジノ シークレット 登録 方法 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.

Hot Water Resistance

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

Soldering Heat Resistance

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

Table 3-1-3 Soldering Heat Resistance of カジノ シークレット 登録 方法P

Sample size:	JIS K7113 No. 1(1/2) dumbbell x 1.2mm
Solder:	H60A (60% tin, 40% lead)

*The values within the above table represent the limit, in seconds (">60" means the product will not deform, even when dipped in a solder bath for 60 seconds).
Blistering may occur, even in temperatures less than the above deformation temperatures, depending on the molding condition.

Long-Term Heat Resistance

カジノ シークレット 登録 方法P has excellent long-term heat resistance. The following data show the relative temperature index (RTI) for カジノ シークレット 登録 方法P. The RTI indicates the temperature at which the impact strength (Imp) and tensile strength (Str) of 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 of the test piece.

Arrhenius Plot

The temperature range where the resin can be used for a long time is limited by the thermal stability of 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 of the aging temperature (K).
