Covestro Bayfit® 566 Polyurethane Flexible Foam System, 80 Index
Categories: Polymer; Thermoset; Polyurethane, TS; Thermoset Polyurethane Foam, Unreinforced

Material Notes: Characterization: Bayfit 566 is a moldable high resilience (HR) polyurethane flexible foam system.

Properties / Applications: Bayfit 566 is a water-blown (MDI)/polyether based foam system used to manufacture high resilience (HR) cold-cure flex molded foam with medium to high load bearing properties. This system is characterized by good flow behavior in a wide variety of parts. Applications include office furniture, recreational seating, armrests and cushions. Bayfit 566 foam made at indices ranging from 80 to 105 typically passes the requirements of CAL-117 for flame resistance. Foams made at higher indices typically do not. As with any product, use of the Bayfit 566 system in a given application must be tested (including field testing, etc.) in advance by the user to determine suitability.
