About floral foam

Floral foam is a type of sponge-like lightweight synthetic plastic with water-absorbing properties that is bought and placed at the bottom of flower vases to support flower stalks. After dry foam for flowers was introduced in the 1950s, its popularity grew rapidly. It has become a popular option for florists, business owners, event planners, and homeowners who wish to keep flower petals and leaves fresh and puffy for a long time.

Having superb qualities, the floral sponge is made of carbon black, formaldehyde, and phenolic acid. Formaldehyde first reacts with phenolic in an airtight chamber and controlled environment to form crumbly plastic.
