Frequently asked questions
What should I include when quoting TPU Gray?
Send the current CAD, quantity and intended use. Add a drawing for critical fits, the required material condition and any finish or inspection requirements. Confirm availability and the delivered specification in the quotation.
Can I use catalog properties as acceptance criteria?
Use the catalog to shortlist a material. Ask for the exact grade data and agreed test conditions before specifying acceptance limits. Geometry, processing and finishing may affect the delivered part.
How do I choose a specialty polymer?
Describe the intended function and the behavior you need, such as repeated flex or a particular contact condition. Confirm the exact offered grade and process in the quotation.
Can flexible parts use the same drawing tolerances as rigid parts?
Review how the part will be supported and measured. Define functional dimensions and inspection conditions appropriate to the material.
