Care Tips and Uses for Styrofoam

What is Polystyrene?

Polystyrene is known as several names, such as styro, styrofoam, polyfoam and even deco foam.

Polystyrene is a plastic filled with air and was invented 50 years ago by the Dow Chemical Company. This foam contains about 90 percent air that is whipped into the plastic during the manufacturing process and then allowed to dry and cure. The combination of air and any combination of styrene, urethane, neoprene or vinyl make polystyrene so light and moisture resistant.

What is polystyrene or Styrofoam used for?

Styrofoam wreaths and shapes are used in floristry to create decorative floral arrangements.

Styro wreaths are widely used as sympathy tributes as flowers for this occasion are prepared before the event and do not need to drink water and last long. The white wreath is wrapped with green plastic wreath wrap to hide the white base and the fresh flowers are wired and inserted into the wreath base.

The main use for Styro wreaths in floral decoration is using them for artificial and dried flower arrangements. They have wire stems and are easy to insert into the foam. Styrofoam is not as soft and dusty as wet or dry floral foam and is often preferred for artificial flower arranging.

Polystyrene/styrofoam hearts, cones, stars and eggs are great for Christmas, Wedding, Valentine’s or Easter craft. High quality Styrofoam/polystyrene can be decorated and painted with acrylic hobby paints, glitters and sequins. Also think about decorating with yarns, strings and threads.

Wrap styro floral foam wreath bases with ribbons, fabrics and other materials to hide the white foam. Polyfoam is safe for kids and often used for faces or planets of the solar system.

Polystyrene boxes are great for packing fruit, vegetables and even fresh seafood as they keep the fresh produce insulated. Polystyrene is also used in the walls of cool rooms for added insulation.

Which glue should I use for gluing polystyrene or Styrofoam?

You can use a spray adhesive to glue polystyrene. Most aerosol adhesives offer a quick, convenient way to glue Styrofoam. These types of glue sprays are designed to work on a variety of surfaces and are multipurpose glues for odd jobs in the home.

Design Master Tack 1000 and Design Master Tack 2000 are suitable aerosol adhesives sprays that can be used to glue polystyrene.

Generally an all purpose PVA glue that is water-based and safe for use by children can be used for gluing Styrofoam. These conventional PVA glues (wood working glue) are thick and suitable for use on virtually all craft surfaces.

Glue has to be tacky style glue. There are specific styro craft glues on the market. Even UHU glue that is used in an office can glue Styrofoam.

When gluing two pieces of Styrofoam together you may wish to consider adding some tooth picks or skewers stuck into and between the foam.

Never use hot glue directly on to Styrofoam. Hot glue is one of the worst glues to use on Styrofoam because it will melt the foam if directly applied. Hot glue is not recommended if you want to attach two Styrofoam pieces together. If you really have no other choice, apply the hot glue to the object that you want attached to the Styrofoam and wait for it to become tacky before applying it to the Styrofoam.

Never use an adhesive that contains a solvent. It will erode the Styrofoam releasing all sorts of toxic fumes.

Choose adhesives that are suited for not porous materials. Styrofoam’s are plastics and plastics are non-porous.
