AI Technical Summary
Existing polyethylene films are prone to static electricity during processing, and the migration of antistatic agents is unstable, affecting processing stability and film quality. At the same time, excessive use of heat stabilizers leads to increased costs, reduced toughness, and higher haze.
By optimizing the chain length ratio and mutual proportion of antistatic agents and heat stabilizers in polyethylene, the migration rate of antistatic agents can be controlled, the acid absorption efficiency of heat stabilizers can be improved, the dispersion effect of nucleating agents can be enhanced, more heterogeneous crystal nucleation sites can be formed, and the haze can be reduced.
This achieves durable antistatic properties, excellent thermal stability and transparency of the film, reduces haze, and improves the optical and antistatic properties of the film.
