Q
Poor Chemical Resistance of CMC
A
Poor chemical resistance is caused by CMC chemical affinity; selecting chemical-resistant grade and coating are the key
Material Analysis CMCchemical resistancechemical attackmicro-crosslinkingsurface coating
Q
Strong Odor in CMC Processing
A
Strong odor is caused by CMC decomposition and volatilization; temperature control and ventilation are the key
Material Analysis CMCprocessing odorvolatilesventilation and exhausttemperature control
Q
Internal Shrinkage Voids of CMC
A
Shrinkage voids are caused by thick-wall shrinkage and insufficient holding; extending holding is the key
Molds & Tooling CMCshrinkage voidthick wallholding timegate freezing
Q
Large Creep Deformation of CMC
A
Large creep is caused by the nature of the elastomer; micro-crosslinking and rigid filler are the key
Material Analysis CMCcreepmicro-crosslinkinghigh molecular weightrigid filler
Q
Poor Antistatic Effect of CMC
A
Poor antistatic effect is caused by insufficient addition; increasing antistatic agent is the key
Molding Process CMCantistaticantistatic agentsurface resistancemigration rate
Q
Processing Temperature Fluctuation of CMC
A
Q
Insufficient Tensile Strength of CMC
A
Insufficient tensile strength is caused by molecular weight and poor interface; selecting a high MW grade is the key
Material Analysis CMCtensile strengthmolecular weightcoupling agentorientation control
Q
CMC Screw Slippage
A
Screw slippage is caused by premature melting; cooling the feeding section is the key
Extrusion & Post CMCscrew slippagefeeding section temperaturepremature meltingflight deepening
Q
Large Dimensional Change of CMC with Temperature
A
Dimensional temperature sensitivity is caused by large thermal expansion coefficient; adding filler and annealing are the key
Extrusion & Post CMCdimensional temperature sensitivitythermal expansion coefficientrigid fillerannealing treatment
Q
CMC Hardness Too High
A
High hardness is caused by crystallization and filler; adjusting cooling and filler are the key
