Expanded form

The main disadvantage to OPS is that it is brittle, and will crack or tear easily. Typical values range from 0. Due to its technical properties such as low weight, rigidity, and formability, EPS can be used in a wide range of applications. Then you have zero tenths.

And you might say hey, how do I know whether I should multiply or add first. Common applications of HIPS include toys and product casings.

Copolymers[ edit ] Pure polystyrene is brittlebut hard enough that a fairly high-performance product can be made by giving it some of the properties of a stretchier material, such as polybutadiene rubber.

And we have four thousandths. The bright, star-shaped hole at the center of the image is an air-gap between the beads where the bead margins have not completely fused.

And we are done. Foams are also used for non-weight-bearing architectural structures such as ornamental pillars. Water absorption of polystyrene foams[ edit ] Although it is a closed-cell foam, both expanded and extruded polystyrene are not entirely waterproof or vaporproof.

In recent years the expanded polystyrene composites with cellulose [28] [29] and starch [30] have also been produced. The boards containing a flame retardant when tested in a tunnel using test method UL or ASTM E84 will have a flame spread index of less than 25 and a smoke-developed index of less than This 5 is in the ones place.

The two such materials can never normally be mixed because of the small mixing entropy of polymers see Flory-Huggins solution theorybut if polybutadiene is added during polymerisation it can become chemically bonded to the polystyrene, forming a graft copolymer ,[ citation needed ] which helps to incorporate normal polybutadiene into the final mix, resulting in high-impact polystyrene or HIPS, often called "high-impact plastic" in advertisements.

Polystyrene

Decomposition X years, still decaying Polystyrene is commonly injection moldedvacuum formedor extruded, while expanded polystyrene is either extruded or molded in a special process.

Several other copolymers are also used with styrene. It literally represents five ones, or you could just say it represents 5. The boards containing a flame retardant when tested in a tunnel using test method UL or ASTM E84 will have a flame spread index of less than 25 and a smoke-developed index of less than Extruded polystyrene material is also used in crafts and model building, in particular architectural models.

And we have four thousandths. And what does this actually represent?. An interactive math lesson about Place Values.
