Grade matching
Compare the current material and mandatory application requirements.
Material validation workflow
Engineering plastic sample testing and trial supply
Plan grade matching, sample testing and trial supply for PA66, PEEK and related engineering plastics before a production decision.
Material answer
A useful material trial begins with the current grade, part drawing, mandatory properties and known processing conditions. Derek-Plastics can support grade matching, sample discussion, test planning and trial supply. The customer then evaluates molding stability, dimensions, appearance and required part performance before approving a production material.
Send the current grade, part application, key requirements and trial timing. We will use them to review a suitable material direction.

Frequently asked questions
Can sample testing support qualification of a replacement grade?
Yes, after the current grade and mandatory requirements are documented. The comparison should cover the current TDS, processing behavior and agreed finished-part criteria rather than relying on material names alone.
What data is required before arranging a material trial?
Provide the current grade, TDS, part drawing, molding equipment, known settings, required test methods, approvals, visible criteria and the reason for the trial. Define pass criteria before sampling.
How are samples and trial testing organized?
First agree on the candidate and relevant checks. Then mold the sample under recorded conditions, inspect the finished parts and compare the results with the approved baseline before discussing trial supply.
What is the MOQ after a successful material trial?
MOQ starts from 500kg. The trial request should identify the validated candidate, color, required documents and expected order timing.
