DuPont Engineering Polymers introduced higher performance and higher productivity acetal resins for injection molders.
The Delrin Eleven P resins have improved fuel resistance vs. comparable acetals, the Wilmington, Del., firm claimed. DuPont also reduced the mold shrinkage to about the same level of competing acetals to allow direct material replacement.
The Eleven P resins have high thermal stability and low mold deposit and can set up as much as 15 percent faster than standard Delrin P grades.
