PP Impact Copolymer
Problem Phenomenon
PP impact copolymer; low-temperature toughness; processing protects the rubber phase.
Cause Analysis
PP impact copolymer; ethylene-propylene rubber phase; low-temperature toughness; processing protection; shear heat management; application matching.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone
Solution
①Impact grades; ②Processing protection; ③Shear heat management; ④Low-temperature verification; ⑤Application matching.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Protecting the rubber phase of PP impact copolymer is the core; shear and temperature management; verification preserves toughness.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
