Q

Gel Particles/Fish Eyes

A

The essence of fish eyes is incompletely melted ultra-high molecular weight components or crosslinked gel in the resin. The solution approach is "raising temperature + filtration + changing material": increase the plasticization temperature to ensure full melting, use filter screens to filter out...
