Polystyrene (PS) / ˌpɒliˈstaɪriːn / is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. [5] . Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to air and water vapor and has a relatively low melting point. [6] .

A classic material choice for takeout containers, PS is a versatile plastic resin used in both foam and rigid forms for food packaging.

A lightweight foam, EPS is very popular for countless craft projects, and its easy to work with. EPS’s unique closed-cell structure allows almost total resistance from moisture & water vapor and will not rot or attract fungi or mildew.

PS is a synthetic aromatic hydrocarbon polymer made by ‘stringing’ together styrene monomers. It can be made as a foam or a solid and used in various consumer products.

Dec 10, 2014 · Find out everything you want to know in our polystyrene foam physical data sheet. We include general information, properties, and potential applications.

Find out key properties, processing & recyclability of Expanded Polystyrene (EPS), a lightweight rigid foam used for packing, insulation etc.

Mar 8, 2022 · KT board（PS foam board) is a new type of advertising material made of PS particles through foaming to form board core and surface lamination. The board body is straight, light, not easy to deteriorate, and easy to process.

Jun 20, 2024 · PS foam exists in two types: extruded polystyrene and expanded polystyrene (abbreviated as XPS and EPS, respectively). EPS has more applications in our daily lives, such as making Styrofoam cups or packing foods for export.

Expanded Polystyrene (EPS), is the generic industry name for a white rigid material made by expanding polystyrene beads with steam and bonding the beads together under pressure in a block or shape mold. EPS is used in the construction industry for insulation and void fill.

PS foam composites with fibers or fillers: These composites combine PS with materials like glass fibers or mineral fillers to improve strength, thermal resistance, or mechanical properties, making them suitable for more demanding applications.
