With SUMIKASUPER LCP, there is a great difference in mold shrinkage between the flow direction (MD) and the direction perpendicular to the flow direction (TD), and anisotropy is large. When considering the dimensions of the mold, set the adjustable mold shrinkage rate to a value between the MD and TD values.
It is recommended that small, thin-walled products in particular be designed with a shrinkage rate of 0% in the MD direction.

One excellent feature of SUMIKASUPER LCP is that its CLTE is extremely low. Its CLTE has linearity with almost no change even when the temperature changes, and the CLTE in the MD direction is the same level as that of metal, which is very low. However, similar to other properties, with LCP, anisotropy exists in the thermal expansion coefficient, and the CLTE in the TD direction becomes large.
Figure 3-3-3 Comparison of the CLTE of SUMIKASUPER LCP with That of Other Resins
The CLTE (Coefficient of linear thermal expansion) is the displacement amount caused by thermal expansion per 1°C of the molding.
Generally, the coefficient of linear thermal expansion indicates the average linear expansion coefficient within a certain temperature range.
The CLTE of SUMIKASUPER LCP differs greatly between the MD and TD according to the filler type, filler amount, and the flow orientation (anisotropy). In this measurement, the difference between MD and TD is clear because the CLTE of the test piece that was machined from the center of the dumbbell test piece, which tends to have relatively large anisotropy.

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.

The specific volume of thermoplastic resin, including SUMIKASUPER, changes according to the pressure regardless of whether it is in a solid or molten state. The compressibility of this resin is expressed as the relationship among Pressure, Specific Volume, and Temperature (PVT characteristics). The volume of crystalline resins such as PPS changes greatly at the melting point (crystallization), but since LCP appears to melt at the liquid crystallization temperature, there is little change in volume due to solidification. There is also little change in volume due to pressure. Therefore, it has excellent dimensional stability.
