Q
Material Hang-up and Carbon Deposits on CMC Extrusion Die
A
Die carbon deposits are caused by thermal oxidation and untimely cleaning; PE flushing and timely cleaning are the key
Extrusion & Post CMC extrusiondie carbon depositPE flushingstagnation zonethermal oxidation
Q
Delamination in Blending CMC with Incompatible Resins
A
Blends with large polarity differences require reactive compatibilizers to form chemical bonding at the interface to solve the problem

Q
Connected Pellets in CMC Extrusion Pelletizing
A
Connected pellets are caused by elastic recovery and low-temperature pelletizing; high-temperature water cutting and fast cutting are the key

Q
Severe Parison Sag in CMC Extrusion '2079851475616104457
A
Parison sag is caused by low melt strength; micro-crosslinking and wall thickness control are the key

Q
Yellowing of CMC Products After Processing
A
Yellowing is caused by thermo-photo-oxidation and metal catalysis; improving the antioxidant system and UV absorber is the key

Q
CMC product long-term storage dimensional change
A
Dimensional change is caused by physical aging; annealing treatment and slight crosslinking are the measures to stabilize the size
Material Analysis CMC dimensional stabilityphysical agingannealingsecondary crystallizationslight crosslinking
Q
CMC extrusion melt fracture
Q
CMC and filler interface bonding poor
Q
CMC injection thick wall bubbles
A
Thick wall bubbles are caused by a combination of insufficient holding pressure, moisture and poor venting
Material Drying CMC injectionbubbleholding pressurethick-walled productmold venting
Q
CMC injection demolding difficult
A
Difficult demolding is caused by adhesion and insufficient mold design; increasing the draft angle is the fundamental measure
