View Typical Property Values

ENSIFONE® is a transparent engineering plastic known for its chemical resistance, rigidity, high-temperature performance, and its ability to operate in an autoclave environment. ENSIFONE® is FDA and NSF compliant and holds its excellent mechanical properties over a wide range of temperatures.

• Autoclave resistance

(ENSIFONE® maintains dimensional stability through repeated autoclaves.)
• Excellent electrical properties
• Good chemical resistance

(ENSIFONE® performs well in mineral acids, alkali, salt solutions, and hydrocarbons.)
• Superior resistance to creep
• FDA and NSF compliant
• High-temperature performance

(ENSIFONE® has a heat deflection temperature of 345°F and a long-term continuous use temperature of 285°F.)
• Excellent hydrolytic stability
• High strength and rigidity
• Flame retardant

(ENSIFONE® is rated UL94 V-O)

ENSIFONE®s unique combination of chemical and hydrolytic resistance, high-temperature performance, good mechanical properties, and agency approvals make it an excellent choice for applications in the pharmaceutical, medical, food service equipment, semiconductor processing, and electronic equipment industries.
