Processing & Quality Control
01 / Mold & Sinter
Two-Step Fabrication
Everflon™ PTFE Granular is processed via cold preforming followed by free sintering above the crystalline melting point (344 °C). Ideal for manual mold charging of large-diameter billets.
02 / Storage Temperature
21–27 °C (70–80 °F)
Maintain resin uniformly within the optimal temperature range prior to molding to eliminate micro-cracking and prevent moisture condensation during compaction.
03 / Compliance & Packaging
FDA & Standard Drums
Complies with FDA 21 CFR 177.1550 and EU 10/2011 for food-contact surfaces. Supplied in heavy-duty 40-kg (88-lb) drums with polyethylene liners.
