It is a smooth, closed cell foam, most commonly referred to as smooth Styrofoam ®. They are different brand names of the same type of plastic, polystyrene or number 6 plastic. The foam used to make cups technically isn’t Styrofoam.) Which is better insulation polystyrene or polyurethane? Production. When building or renovating a high-performance building envelope there are really three main kinds of rigid foam panels you are going to have to choose from - Polyisocyanurate known as Polyiso (PIR), Extruded Polystyrene (XPS) - often called Styrofoam - and Expanded Polystyrene (EPS). Polystyrene results when styrene monomers interconnect (polymerization). Safety Issues Many believe that fiberglass insulation is in itself a hazardous material, citing the fact that it had been found by the International Agency for Research on Cancer as "possibly carcinogenic" in 1988.

See the difference between STYROFOAM Brand Foam products and expanded polystyrene, which is often mistakenly referred to as Styrofoam. Polystyrene . extruded polystyrene foam. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year. Expanded vs. Extruded Polystyrene XPS & EPS Differentiators It must also be noted that stated R-values of insulations products vary under different conditions and truly credible comparisons must take into consideration the specific brands of foam and specific test conditions. When you search the web you will find all three. Deciding which material to use when insulating the walls of your home can be difficult. Polyisocyanurate (PIR), Extruded Polystyrene (XPS), Expanded Polystyrene (EPS) or Styrofoam? Referensi: 1. It is wrongly applied to expanded polystyrene foam used to form products. Expanded Polystyrene Polystyrene beads are often mistakenly referred to as STYROFOAM™ beads. The puffing of EPS resin, creating the puffed polystyrene beads is the first step in producing EPS (expanded polystyrene) blocks. The product was originally designed for use in thermal insulation. When laminated into a 1″ thick panel with standard 1/8″ substrates and aluminum skins, the polystyrene panel yields a total R-value of approximately 4.7 while the Polyisocyanurate panel will achieve an R-value of 6.4. As the experts in EPS foam block construction, we’re here to set the record straight about extruded vs expanded polystyrene so you can be better informed as a consumer in the type of materials you invest in for your next project. This is a relatively simple project that can reap great benefits, but with the wide variety of approaches you can take to insulate your garage, how do you choose the one that is right for you? Polystyreen (afgekort PS) is een thermoplastisch polymeer van het monomeer styreen.Het is een kunststof van petrochemische oorsprong. Styrofoam is in fact (as answered by others) a trade name of DOW Chemical for expanded polystyrene (XPS), i.e. It is the white brittle material that is frequently used in shipping to protect the goods inside. You may actually be looking for an expanded polystyrene (EPS) product. Celotex/kingspan have far better thermal values than polystyrene, it was always Jablite(polystyrene) under concrete house floors,now its 75mm kingspan/celotex. STYROFOAM™ vs EPS What's the difference between EPS and STYROFOAM™? Typically, you can count on a rating of R2 per inch up to a value of around R10. McIntire said his invention of foamed polystyrene was purely accidental. It is molded from tiny beads into many shapes like balls, bells, eggs, miniature fruit shapes and more. Polystyrene is pre-formed to the steel panels and is usually glued to both the front and back of the inside of the panel. Polystyrene insulation is commonly known as foam insulation or by its brand name, Styrofoam. The foam variety of polystyrene is often referred to as Styrofoam. It is actually an extruded closed cell polystyrene material." Dow Chemical’s Styrofoam Brand Foam also covers a full range of foam products for the floral, craft and special events industries. I have been looking for a good price on some balls to cover. 12 years ago. [/background] [background=rgb(224, 224, 224)]Polystyrene is used in making expanded polystyrene (EPS) … EPS is an "Expanded Polystyrene" foam like you see in drink coolers It is like photocopier which is more known as Xerox (brand name of … for EPS). Differences Between Styrofoam™ and EPS. Is there a difference between the two? This makes polystyrene much less versatile of a resource, capable of packaging reuse, and much more of a hazard to society. Polystyrene can be naturally transparent, but can be coloured with colourants. The Advantages of Expanded Polystyrene. It is a synthetic polymer made of monomer styrene. Because of its smooth surface it is excellent for painting. Polyurethane — The higher density of polyurethane makes it more expensive, but also a better insulator […] Polystyrene (left) is a synthetic aromatic polymer made from the monomer styrene which is also known as Styrofoam. Both Paper and Polystyrene Foam Have Advantages Extruded polystyrene is about as strong as an unalloyed aluminium but much more flexible and much less dense (1.05 g/cm 3 for polystyrene vs. 2.70 g/cm 3 for aluminium). Its lightness makes it easy to handle and install. So let’s take a look at the differences. construction industry. Styrofoam is a trademark brand of extruded polystyrene foam, which is manufactured by Dow Chemical. Extruded polystyrene is much denser than expanded polystyrene (2.18 lbs. PS is made by the polymerization of styrene which is a kind of building block material used to produce a variety of plastic products. As we said, Styrofoam™ is a Dow trade, blue in color, and is an extruded polystyrene (XPS) foam made for thermal insulation, construction and craft applications. 4 years ago. EPS is a lightweight insulator with a high mechanical resistance. Polyisocyanurate’s typical R-value for the same 1″ of material is approximately 6.0. Uses include protective packaging (such as packing peanuts and CD and DVD cases), containers (such as "clamshells"), lids, bottles, trays, tumblers, disposable cutlery and in the making of … Extruded Polystyrene Foam vs. Styrofoam: What's the Difference?

His invention came about as he was trying to find a flexible electrical insulator around the time of World War II. 0 0. (Polystyrene cups are commonly called Styrofoam cups, but Styrofoam is a trademarked name for a similar product that’s used to insulate buildings. This foam is rigid but able to absorb and disperse significant pressure due to its structural strength and low density. While polystyrene has higher density that doesn’t allow it to float on water, styrofoam can easily float on water because of lower density. Polystyrene has a typical R-value of approximately 4.4 per 1″ thickness of material. Comparing the sustainability, cost efficiency, ... Styrofoam packaging products can leach styrene into their surroundings and even into the products they protect. Polystyrene vs. Polyurethane Garage Door Insulation.
