POM product brittle cracking

Brittle cracking = decomposition or stress, distinguish first by smelling the odor.

Material Analysis POM；brittle cracking；decomposition；stress concentration；regrind

POM melt temperature exceeding standard decomposition (formaldehyde release)

POM melt temperature is a safety red line, not a quality preference.

Material Analysis POM；thermal decomposition；formaldehyde；melt temperature；splashing
