TECAFORM® FG Blue (Food Grade Acetal Copolymer)
TECAFORM® FG Blue is Ensinger's new blue colored acetal designed specifically for the food industry. TECAFORM® is resistant to hot water, and typical cleaning chemicals, and it possesses good bearing and wear properties. Its blue color makes it more visible than standard grades. TECAFORM® is commonly used as bushings, rollers, wear strips and other applications requiring a combination of strength, low moisture absorption, chemical resistance and dimensional stability.
- No centerline porosity
- Low moisture absorption
- Excellent machinability
- Good combination of mechanical properties
- Resistance to food industry cleaning chemicals
TECAFORM® FG BLUE is resistant to aqueous solutions with pH values ranging from 4 to 14. - Good wear and abrasion properties
- TECAFORM® FG Blue is manufactured from resin and color components that are FDA, USDA, and 3A Dairy compliant
- Good dimensional stability
- Good property retention at elevated temperatures
TECAFORM® is used in a wide variety of food industry applications requiring good strength and toughness, dimensional stability, wear resistance and the ability to operate in a wet environment with little absorption. Material handling, filling and bottling equipment are some of the common machines utilizing TECAFORM®'s combination of properties. Typical applications are gears, wear strips, bushings, pump parts, fittings and rollers.
