Practical answers to common plastic material challenges

740 questions
Q
EEA Large Compression Set
A
Large compression set is caused by insufficient crosslinking; increasing crosslinking degree is key
Molding Process EEA compression set crosslinking degree elastic recovery reinforcing filler
Q
EEA Surface Stress Whitening
A
Stress whitening is caused by orientation and internal stress; reducing orientation and annealing are key
Molding Process EEA stress whitening orientation stress annealing treatment stress concentration
Q
Coarse EEA internal crystallization
A
Coarse crystallization is caused by slow cooling; fast cooling and nucleating agent are key
Molding Process EEAcoarse crystallizationspherulite refinementnucleating agentcooling rate
Q
Material sticking to the sizing sleeve of EEA extruded pipe
A
Sizing sleeve sticking is caused by elastomer adhesion characteristics; polishing and lubricating water are the key
Molding Process EEA pipesizing sleeve stickingpolishinglubricating waterelastomer adhesion
Q
EAA hardness too low
A
Low hardness is caused by material softness and excessive plasticization; adding filler is key
Molding Process EAAlow hardnessrigid fillerplasticizercrystallization control
Q
Large EAA impact strength fluctuation
A
Impact fluctuation is caused by unstable dispersed phase and crystallization; stable processing is key
