Did you throw away the green sponge for flower arrangement after use?

You can't throw it away. You can keep it.

Sponge is a porous material with good water absorption and can be used for cleaning articles. Sponges commonly used by people are made of lignocellulosic fibers or foamed plastic polymers. In addition, there are natural sponges made of sponges, which are mostly used for body cleaning or painting. In addition, there are three kinds of synthetic sponges made of other materials, namely low-density polyether (non-absorbent sponge), polyvinyl alcohol (super absorbent material without obvious pores) and polyester. PU sponge mainly includes polyester and polyether, which can be sliced or rolled, and can also be processed by compound processing, hot pressing and sandblasting according to customer requirements. PU sponge is involved in various industries, including automobile industry, battery industry, cosmetics industry, bra and underwear manufacturing industry and high-end furniture manufacturing industry, because of its characteristics of heat preservation, heat insulation, sound absorption, shock absorption, flame retardant, antistatic and good air permeability.
