HDPE is a rigid yet slightly flexible material that maintains its shape under normal handling stress. Note that HDPE is not recommended for autoclaving and may be affected by concentrated oxidizing acids and certain aromatic or chlorinated solvents at elevated temperatures.\u003c\/p\u003e\n\u003ch2\u003eQuality \u0026amp; Procurement\u003c\/h2\u003e\n\u003cp\u003eMade in USA, Caplugs® Evergreen screw caps are manufactured under ISO 9001 quality management from BPA-free, phthalate-free, latex-free resin.
