Praktische Antworten auf häufige Herausforderungen mit Kunststoffmaterialien

11636 Fragen
Q
POE product elliptical deformation
A
Elliptical deformation is caused by asymmetric demolding force; uniform ejection is key
Molds & Tooling POEelliptical deformationsymmetric ejectionuniform coolingsizing time
Q
POE film moisture barrier insufficient
A
POE moisture barrier insufficiency requires thickening, co-extrusion and coating to improve
Material Drying POE filmmoisture barrierWVTRPOE/HDPE co-extrusionPVDC coating
Q
POE film self-adhesion too strong
Q
POE internal delamination cracking
A
Internal delamination is caused by poor interface and shrinkage difference; compatibilizer and uniform cooling are key
Extrusion & Post POEinternal delaminationinterfacial adhesioncompatibilizeruniform cooling
Q
POE surface snakeskin pattern
A
Snakeskin pattern is caused by low-temperature extrusion and elastic recovery; raising temperature and reducing speed are key
Extrusion & Post POEsnakeskin patternextrusion temperatureelastic recoverydie temperature control
Q
POE internal black speck carbonization
A
Black specks are caused by thermal carbonization and carbon deposits; lowering temperature and regular cleaning are key
Processing Machinery POEinternal black speckthermal carbonizationscrew cleaningtemperature control
Q
POE product twist deformation
A
Twist deformation is caused by asymmetric cooling; symmetric cooling is key
Molds & Tooling POEtwist deformationsymmetric coolinggate arrangementannealing
Q
POE/carbon black conductivity unstable
A
Conductivity stability is affected by dispersion and network breakage; supercritical addition is needed
Material Analysis POE conductivitycarbon black dispersioncritical concentrationconductive networkcarbon black structure
Q
POE flexural modulus low
A
Low flexural modulus is caused by soft material and insufficient filler; adding rigid filler is key
Material Analysis POEflexural modulusrigid fillernucleating agentcrystallinity
Q
POE film puncture strength low
A
Low puncture is caused by low modulus and thin thickness; thickening and stiffening
