Q
DSTDP large impact strength fluctuation
A
Impact fluctuation is caused by dispersed phase and crystallization instability; stabilizing processing is key
Molding Process DSTDPimpact fluctuationdispersed phase particle sizenucleating agentprocessing stability
Q
DSTDP poor antistatic effect
A
Poor antistatic effect is caused by insufficient addition; increasing antistatic agent is key
Molding Process DSTDPantistaticantistatic agentsurface resistancemigration rate
Q
DSTDP processing temperature fluctuation
Q
DSTDP surface stress whitening
A
Stress whitening is caused by orientation and internal stress; reducing orientation and annealing are key
Molding Process DSTDPstress whiteningorientation stressannealing treatmentstress concentration
Q
DSTDP large compression set
A
Large compression set is caused by insufficient crosslinking; increasing crosslinking degree is key
Molding Process DSTDPcompression setcrosslinking degreeelastic recoveryreinforcing filler
Q
DSTDP internal coarse crystallization
A
Coarse crystallization is caused by slow cooling; fast cooling and nucleating agent are key

Q
DSTDP extruded film thick edges and thin middle
A
U-shaped thickness is caused by die flow channel and swell differences; coat-hanger die and gap fine adjustment are key

Q
Insufficient Dissolution in CMC Solution Preparation
A
CMC dissolution needs pre-dispersion and full stirring to prevent surface gel coating
Molding Process CMC dissolutionpre-dispersionstirring speedsurface gel layerdissolution time
Q
CMC Hardness Too Low
A
Low hardness is caused by material softness and excessive plasticization; adding filler is the key
