Why EPS Styrofoam is also called foam

The chemical name of styrofoam is EPS, the full name is expandable polystyrene, also known as expandable polystyrene. mainland China commonly known as foam, Hong Kong commonly known as styrofoam, Taiwan commonly known as styrofoam. EPS polystyrene foam is a material formed from polystyrene (PS) and a blowing agent at high temperatures, often referred to as "foam". During heating and forming, containers such as disposable tableware, fresh tray, instant noodle bowl and hamburger box can be made according to different foaming ratios. It can also be used as a shockproof packaging pad, light weight, strong and durable.

EPS styrofoam is a kind of polymer material formed by a large number of gas micropores dispersed in solid plastics. It has the characteristics of light weight, heat insulation, sound absorption, shock absorption, etc., and its dielectric performance is better than that of matrix resin. It has a wide range of uses. Almost all kinds of plastics can be made into EPS foam, and foam molding has become an important field in plastic processing.
EPS Features
(1)EPS Polaroid bulk density is very low, can reduce the packaging weight, reduce transportation costs;
(2)EPS has excellent shock and vibration energy absorption, which can greatly reduce the damage of products for cushioning and shockproof packaging;
(3)EPS stouflon has strong adaptability to changes in temperature and humidity, and can meet the requirements of general packaging conditions;
(4) the water absorption rate is low, the moisture absorption is small, the chemical stability is good, itself will not produce corrosion to the contents, and the acid, alkali and other chemicals have strong tolerance;
(5)EPS has low thermal conductivity and can be used for thermal insulation packaging, such as ice cream cups, fast food containers and insulated fish boxes;
(6) The molding process is convenient, and various foam pads, foam blocks, sheets, etc. can be made by molding, extrusion, injection and other molding methods. It is easy to carry out secondary molding processing, such as foam board can be made into various fast food containers by thermoforming. In addition, EPS styrofoam can also be used for self-bonding or bonding with other materials to make various cushioning pads.
