Q
DSTDP unstable shrinkage rate
A
Unstable shrinkage rate is caused by batch differences and temperature fluctuation; raw material and temperature control are key
Material Analysis DSTDPshrinkage ratebatch differencestable temperature controlcrystallinity consistency
Q
DSTDP internal coarse crystallization
A
Coarse crystallization is caused by slow cooling; fast cooling and nucleating agent are key
Molding Process DSTDPcoarse crystallizationspherulite refinementnucleating agentcooling rate
Q
DSTDP purging difficulty
A
Purging difficulty is caused by strong DSTDP adhesion; PE flushing and temperature reduction are key
Processing Machinery DSTDPpurging difficultyadhesionPE flushingdedicated purging compound
Q
DSTDP exudation to product surface
A
DSTDP exudation is caused by poor compatibility and excessive addition; reducing amount and improving compatibility are key
Material Analysis DSTDP exudationcompatibilityaddition amountthioester typesurface exudation
Q
DSTDP extruded pipe ovality exceeding standard
A
Ovality is caused by uneven cooling and clamping; annular cooling and uniform haul-off are key

Q
DSTDP poor weather resistance
A
Poor weather resistance is caused by photo-oxidation; UV+HALS+antioxidant triple protection is key
Material Analysis DSTDPweather resistanceUV absorberHALSphoto-oxidation
Q
DSTDP extruded film transverse ripples
A
Transverse ripples are caused by haul-off vibration and roller eccentricity; equipment overhaul and stable control are key
