PBAT excessive cost
Problem Phenomenon
PBAT raw material cost is more than 3 times that of ordinary PE, product price competitiveness is weak, and market promotion is limited.
Cause Analysis
PBAT synthesis process is complex and raw material cost is high; production capacity scale is limited; filler addition is limited so cost reduction space is small; thickness demand increases material usage; the recycling system is imperfect.
Solution
①High-filling filler modification to reduce cost; ②thickness optimization and thinning; ③multi-layer structure to reduce PBAT usage; ④recycled material utilization; ⑤large-scale procurement negotiation.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PBAT cost is the main obstacle to industrialization; high filling of filler and thinning are effective paths; multi-layer structure is the technical cost-reduction direction.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
