Problem & Solution

Q

Metallocene linear low density polyethylene film gel particles/gel granules（Variant: Startup Commissioning Scenario）

A

Gel particles are caused by insufficient plasticization or raw material quality problems, and need to be solved from temperature control and raw material quality.Targeted preventive measures need to be taken in different production scenarios.
