Polystyrene foam is a lightweight, strong plastic with natural shock absorption and moisture resistance. It can be shaped into various products, including packaging, insulation, and food storage containers, and offers effective thermal insulation.
Polystyrene foam is a type of plastic made from petroleum-based hydrocarbon particles infused with air. This material can be extruded or shaped to form shipping and packaging products, food storage containers, or even building insulation. The manufacturing process to make this foam gives this material a uniform and consistent cellular structure which makes it very stiff and strong. In addition to its strength and stability, polystyrene foam offers a number of additional benefits, including effective insulating properties, natural resistance to moisture and the ability to absorb shock or impact.
One of the main advantages of this material is its high strength-to-weight ratio. Polystyrene foam is very strong, but consists mostly of air, resulting in a very low weight. Its light and airy texture allows this material to be easily shaped or molded to form a variety of products. It can be formed into custom packing or shipping containers or cut to fit wall cavities on a construction site. Even expanded polystyrene sheets can be cut using just a simple utility knife rather than complex tools or saws.
The many air cavities within the polystyrene foam also give it natural shock absorption abilities. This makes this material an effective option for protecting fragile electronics during shipping. Many manufacturers create custom packing containers that reduce the risk of damage to electronics and other devices and can absorb shock or impact if the item is dropped in transit. This material is also used to make meat packing trays and egg crates due to its ability to protect these items from damage.
Polystyrene foam is also highly resistant to moisture. When used for packing and shipping, this foam protects items from rain and other sources of moisture. It can be used to hold food or drinks and will not leak or penetrate container walls. When used as building insulation, the moisture resistance of this foam offers many advantages over traditional fiberglass insulation. Unlike fiberglass, foam does not rot, mold, or lose its effectiveness when exposed to moisture.
Another major benefit associated with polystyrene foam is its ability to act as an effective insulator. When used in food preservation, this foam keeps hot foods hot and cold foods cold as they are transported from a restaurant to the home. This foam can also be used to insulate a freezer or refrigerator. When used as building insulation, this material offers a much higher level of thermal resistance than standard fiberglass blankets or mats. This helps maximize the energy efficiency of the facility and keep energy bills as low as possible.
