1️⃣ Surface Defects (Pitting, Dullness):
💡 Solution: Increase processing temperature; add Dispersants or Brightening Masterbatch for a premium finish.
2️⃣ Warping & Shrinkage (Dimensional Instability):
💡 Solution: Slow down the cooling rate; incorporate CaCO3 (Calcium Carbonate) Filler or Talc Masterbatch to enhance stability.
3️⃣ Brittleness & Low Impact Strength:
💡 Solution: Reduce filler ratio; blend with LLDPE/POE or add Toughening/Stiffening Masterbatch to boost durability.
4️⃣ Blocking & Demolding Issues (Sticky Film):
💡 Solution: Add Slipping & Anti-blocking Masterbatch; slightly lower the processing temperature for smoother release.
5️⃣ Bubbles, Flow Marks & Moisture:
💡 Solution: Ensure raw materials are pre-dried; enhance venting; or simply add Desiccant (Anti-foaming) Masterbatch to absorb moisture.
6️⃣ Poor Transparency:
💡 Solution: Minimize filler usage; add Clarifying/Nucleating Masterbatch to achieve crystal-clear results.
7️⃣ Aging & Yellowing (UV Degradation):
💡 Solution: Add Anti-aging & UV Stabilizer Masterbatch to extend outdoor product life.
8️⃣ Color Spots & Inconsistency:
💡 Solution: Switch to Professional Color Masterbatch; add dispersants; reduce screw speed; and limit the use of recycled materials.
