WebDisplayed in Figure 3 are the CTE values measured on an epoxy printed circuit board below and above Tg. Figure 3. TMA results on epoxy PCB showing assessment of coefficients of thermal expansion Below Tg, the printed circuit board has a CTE value of 50.5 µm/m°C, while above Tg, the value of the CTE increases to 270.7 µm/m°C. WebThe only polymer with zero water absorption is PTFE. Plastics with very low water absorption are polymers such as PEEK, PPS, PSU, PPSU, PEI, PVDF, PET, PPE, PP and PE. Furthermore, low water absorption is exhibited by POM, PA12, PC and ABS. Polyamides (nylons) generally show higher water absorption than other engineering …
