Media Features:


~Generally used for severe chemical environments at high temperatures

~Excellent resistance to acids, alkalies, hydrolysis, oxidation, solvents

~Abrasion resistance is generally superior to protein fibers but not as good as most synthetics

~Requires a 20 verticalwire minimum support cage when used in tubular bag form

~Expensive-excellent chemical and thermal resistance

~Continuous operating temperature 500oF (260°C)
