High Corrosive

Frequently Asked Questions

• 01What's the typical plastics used with high corrosive condition?

  uPVC, flame-retardant grades, POM, engineering plastics with acidic/basic additives.

• 02What are the typical applications for high corrosive plastics?

  3C electrical parts, connectors, medical components, chemical-resistant containers, construction profiles.

• 03What are the main screw and barrel requirements for corrosive plastic processing?

  Screw barrel material should be corrosive-resistant, like stainless steel, chrome plated, bimetallic casted or PVD coating base.

• 04What happens when a standard screw and barrel is used with corrosive plastics?

  Rapid corrosion, pitting, surface degradation → metal ion contamination, increased roughness, material buildup, premature failure.

• 05How do I select screw and barrel materials for highly corrosive plastics?

  The selection of matetrial should consider exact polymer processed, else additives like glass fiber and product requirement.
