Styrofoam: History, Properties and Building Applications

Styrofoam is a brand name for Polystyrene Thermal Insulation material (sometimes referred to as “extruded polystyrene foam”). It is a trademark of Dow Chemical and among the most popular plastics in use today. Styrofoam is manufactured in blue sheet foam. It is mostly used in building materials and pipe insulation. It was invented in during World War II by Ray McIntire as he sought to create a flexible electrical insulator. It is usually supplied to manufacturers in form of small foam beads. It can be molded and processed to fit different purposes. The word Styrofoam is inappropriately used in Canada and the United States to refer to expanded polystyrene foam such as cushioning material in packaging, coolers, and disposable coffee cups. These are made of expanded polystyrene beads, and not from the extruded polystyrene normally used in Styrofoam insulation. There is also a different form of Styrofoam used in craft applications which is green and white in color.

The Properties of Styrofoam

Chemical Representation
Styrofoam’s chemical representation comprises of a hydrocarbon chain linked with a phenol group to every single carbon group. Styrofoam’s chemical equation has a (Ph) with a C6H5 ring.

Polystyrene
Polystyrene’s density is 1050kg/m3 as compared to water which has a density of 1000kg/m3. Although it is denser than water, polystyrene floats and doesn’t sink. It can break down when combined with a strong acid.

Polymer and Thermoplastic
A polymer is a Styrofoam molecule. It is an extensive chain of recurring atoms through the connection of many molecules (monomers) derived from petroleum. Styrofoam is also a thermoplastic as it hardens when cooled and softens when heated. As a liquid, it can be easily molded which makes it suitable for various applications in different industries.

Shock Absorber and Lightweight
Styrofoam is an excellent shock absorber and extremely lightweight. It is composed of approximately 90 percent air. This is why expanded polystyrene is very popular as a cushioning material. Styrofoam is easy to transport as its shock-absorbing features keep it well protected from harm.

Insulator
It is a superb insulator that limits thermal transfer. This major aspect makes it a top insulating material as it effectively maintains a comfortable temperature indoors, regardless of the weather conditions outdoors.

The Uses of Styrofoam in Buildings

Insulation
Styrofoam is used by many builders as an insulating material. It has a closed cell structure which ensures its insulation has a high R-value (a material’s ability to conduct heat). The more value a material has, the more resistance it has to conducting heat. When a building is properly insulated, heat is not transferred out of a building or into it which reduces drafts and decreases cooling and heating costs. Styrofoam is used to insulate basement walls, underground walls, and above ground walls as it significantly reduces energy loss. It is cut into sheets that are attached to a building’s frame or installed in its outer foundation walls. The foam is afterwards covered with certain material to create a specific look, such as marble, stone, or stucco. Styrofoam is also used in insulating floors and roofs. On roofs, it is cut and positioned to provide the proper drainage. Plywood or other materials are placed over Styrofoam after it has been laid on ceiling material. Afterwards, shingles can be installed on top. Styrofoam is used on floors as it is an excellent load-bearing material for different types of floors. Its closed cell structure makes it very rigid and highly resistant to compression in load-bearing applications. Styrofoam is also used in commercial and industrial piping applications. It is used in low-temperature systems to prevent surface condensation and to minimize heat gain. It retains its main insulating properties in environments with high-moisture conditions, high humidity and in low-temperature applications.

Waterproofing
Styrofoam’s insulation structure leaves virtually no vacant space between the cells which makes it waterproof and strong. It has a natural resistance to water vapor, snow, and rain and retains its primary physical integrity and insulation performance in exposed conditions for a long time. Since the material is resistant to water, mold and mildew cannot grow on its surface.

Hygiene
Styrofoam has a low susceptibility to rot hence fungal and mold growth and reduced. The boards are odorless, clean and unaffected by dust. This ensures that a structure’s integrity is maintained and the occupants stay in a hygienic environment.

Permanent Laser Hair Removal Brisbane

Laser Hair Removal is a becoming a popular treatment, as the current fashion for both men and women is to have the clean look consisting of little or no body hair. Excess or unwanted hair growth is usually a result of genetics, hormones or certain medications. Recent advances in the technology have meant that the hair removal treatments are now a lot more effective and there is less risk of side effects from occurring, making it safer for consumers.

When discussing Laser Hair Removal, it is important to note that the body has 3 cycles of hair growth – Anagen (active), Catogen (transitional) and Telogen (resting). The laser energy destroys hairs in the Anagen or active phase, targeting the cells at the base of the hair follicle which are responsible for hair growth. As Laser Hair Removal targets only the hairs in the active phase, only a percentage of hairs are treated with each session. A series of treatments is required to clear an area, though less hair will return with each treatment and the regrowth will become fine, soft and sparse.

Laser hair removal treatments target melanin which is the dark pigment contained within the hair. Red hair contains a different type of melanin and consequently the treatments can be less effective for redheads.
The area must be shaved prior to treatment to allow the laser energy to be directed under the skin, and not to heat up the surface by having dark hair above the skin level. Any plucking or waxing must be stopped for several weeks before starting treatment, as the hair needs to be in the follicle for it to work.

The effectiveness of the Laser Hair Removal treatments is mostly dependant on the quality of machine used, the parameters or correct setting and proper candidate selection. An ideal candidate for Laser Hair Removal has light coloured skin and dark coloured hair. This stark contrast of colour allows the laser light to easily target the hair and pose little or no risk of harm to the skin. This is also why it’s important to avoid sun exposure and tanning when undergoing a course of permanent hair removal treatments.

It is important for the full area to be treated by the laser with each hair removal appointment so hairs are not missed. Any missed patches will require additional treatments in the future and the area may look patchy or have uneven hair growth. Hairs that do not fall out or shed within about 14 days have usually not been treated effectively. This is due to poor spacing by the operator or incorrect technique, which can often be avoided by finding a reputable laser clinic that has licensed and experienced operators.
