Q
Modified cellulose acetate butyrate weather resistance not up to standard
A
Weather resistance needs to be addressed from UV absorbers and antioxidants
Material Analysis weather resistanceultravioletantioxidantyellowing
Q
Unsatisfactory toughening effect of modified cellulose acetate butyrate
A
Toughening effect needs to be addressed from addition amount, compatibility and dispersion
Material Analysis tougheningimpact strengthcompatibilitydispersion
Q
Low PVA flexural modulus
A
Low flexural modulus is caused by soft material and insufficient filler; adding rigid filler is the key
Material Analysis PVAflexural modulusrigid fillernucleating agentcrystallinity
Q
Large smoke in PVA processing
A
Large smoke is caused by volatiles evaporation; temperature reduction and exhaust are the key
Material Analysis PVAprocessing smokevolatilesexhaust systemtemperature reduction
Q
Insufficient PVA toughness, brittle fracture
A
Insufficient toughness is caused by low molecular weight and coarse crystallization; selecting high MW is the key
Material Analysis PVAinsufficient toughnessmolecular weightcrosslinking controlcrystallization refinement
Q
Poor PVA chemical resistance
A
Poor chemical resistance is caused by PVA chemical affinity; selecting chemical-resistant grade and coating are the key
Material Analysis PVAchemical resistancechemical attackslight crosslinkingsurface coating
Q
Large odor in PVA processing
A
Large odor is caused by PVA decomposition and volatilization; temperature control and ventilation are the key
Material Analysis PVAprocessing odorvolatilesventilation and exhausttemperature control
Q
Large PVA creep deformation
A
Large creep is caused by the elastomer nature; slight crosslinking and rigid filler are the key
Material Analysis PVAcreepslight crosslinkinghigh molecular weightrigid filler
Q
PVA processing temperature fluctuation
Q
Insufficient PVA tensile strength
A
Insufficient tensile strength is caused by molecular weight and poor interface; selecting a high MW grade is the key
Material Analysis PVAtensile strengthmolecular weightcoupling agentorientation control
