Does PS mean polystyrene?
Polystyrene (PS) /ˌpɒliˈstaɪriːn/ is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle….Polystyrene.

What does 6 PS mean on Styrofoam?
Polystyrene
Polystyrene is one type of plastic which can be identified by finding a #6 “PS” symbol, and includes all foam products like Styrofoam, and some hard plastics like disposable straws and flatware.
What is the thermal conductivity of polystyrene?
The thermal conductivity of expanded polystyrene foam of density 20 kg/m3 is 0.035 – 0.037 W/ (m·K) at 10 °C.
Is PS plastic safe?
The result of these evaluations: FDA for decades has determined that polystyrene is safe for use in contact with food. In addition, FDA has approved styrene as a food additive – it can be added in small amounts to baked goods, frozen dairy products, candy, gelatins, puddings and other food.
Is PS plastic BPA free?
Items with BPA content: Avoid plastics with symbol # 3 (PVC or polyvinyl, which contains phthalates), symbol # 6 (PS or polystyrene foam or Styrofoam) and symbol # 7 (other, including BPA). Do not microwave food/beverages in plastic.
Is Type 1 plastic safe?
Usually clear in color, the vast majority of disposable disposable beverage and food containers and bottles are made of #1 plastic. This plastic is relatively safe, but it is important to keep it out of the heat or it could cause carcinogens (like the flame retardant antimony trioxide) to leach into your liquids.
What is expanded polystyrene EPS?
EPS is a rigid, closed cell, thermoplastic foam material. It is produced from solid beads of polystyrene. Expansion is achieved by virtue of small amounts of gas contained within the polystyrene bead. These cells occupy approximately 40 times the volume of the original polystyrene bead.
What is expanded polystyrene insulation?
Expanded Polystyrene Insulation, more commonly referred to as EPS, is a closed cell insulation that has been around since the 1950’s. EPS is made of 98% trapped air and only 2% plastic, making it an efficient insulator with a small amount of raw material.
What is expanded polystyrene (EPS) exactly?
Expanded Polystyrene (EPS) is the generic industry name used for white rigid material made from the expanded polystyrene beads . It is a lightweight, rigid, plastic foam insulating material produced from solid beads of polystyrene.
What is expanded polystyrene (EPS) foam used for?
Expanded PolyStyrene (EPS) is a white foam plastic material produced from solid beads of polystyrene. It is primarily used for packaging, insulation etc. It is a closed cell, rigid foam material produced from: Both styrene and pentane are hydrocarbon compounds and obtained from petroleum and natural gas byproducts.
How is expanded polystyrene beads made?
Expanded Polystyrene is made by injecting thousands of polystyrene beads into a rectangular or special shaped mold . The polystyrene beads are heated with steam. The bead will then soften and expand up to forty times its original size. At first the beads expand outwardly inside the mold until there is no more room.
What is the difference between EPs and XPS?
EPS (expanded) and XPS (extruded) are both closed-cell rigid insulation made from the same base polystyrene resins and manufactured differently, EPS is beads that are molded or cut into various sizes and shapes while XPS is extruded sheets.
