DSTDP large dimensional change with temperature
Fenómeno del problema
DSTDP product dimension changes >2% in the range of -20 to 60°C
Análisis de la causa
DSTDP thermal expansion coefficient large; crystallinity on the low side causing high temperature sensitivity of dimensions; not annealed, residual stress present
Solución
1) Add rigid filler to reduce thermal expansion coefficient; 2) annealing treatment to stabilize dimensions; 3) select high crystallinity grades to reduce temperature sensitivity
Conclusión clave
Dimensional temperature sensitivity is caused by large thermal expansion coefficient; adding filler and annealing are key
