Package Handling Sorter

Before PolySource

package handling sorter package handling sorter

OEM specified and was using DELRIN® 100P.

However

  • Lead time on purchasing product by current supplier extended to “we don’t know when we can ship your order”.
  • No commitment from supplier meant an expected production shutdown.

Application Requirements

  • Similar mold shrinkage to DELRIN® 100P.
  • Provide comparable dimensional stability to the current material.
  • Provide stiffness and impact strength to meet the demanding requirements.
  • Provide low coefficient of friction, (COF), to provide needed lubricity during operation.
  • Chemical resistance to greases and lubrication oils found in the package handler operation.
  • New product needed to be tested and approved ASAP
