PS sheet refers to Polystyrene sheet, which is a type of thermoplastic polymer commonly known as styrofoam or foam board. Polystyrene is a versatile material widely used in various industries due to its lightweight, rigid, and insulating properties. PS sheets are produced by extruding or molding polystyrene resin into flat, thin sheets.

There are two main types of PS sheets:

Extruded Polystyrene (XPS) Sheet: XPS sheets are made by extruding the polystyrene resin through a die to form a continuous sheet. XPS sheets are commonly used for thermal insulation in buildings, as they have excellent insulating properties and can be easily cut to fit into various shapes.

Expanded Polystyrene (EPS) Sheet: EPS sheets are made by expanding polystyrene beads using steam, resulting in a foam-like structure. EPS sheets are lightweight, rigid, and have good shock-absorbing properties, making them suitable for packaging, cushioning, and disposable food containers.

Key characteristics of PS sheets include:

Lightweight: Polystyrene sheets are relatively light, which makes them easy to handle and transport.

Insulating: Both XPS and EPS sheets have good thermal insulation properties, making them suitable for use in construction and packaging applications.

Low Water Absorption: Polystyrene sheets have low water absorption, which helps maintain their mechanical properties even in damp conditions.

Rigid: The molecular structure of polystyrene provides rigidity to the sheets, making them suitable for various structural and protective applications.

Ease of Fabrication: PS sheets can be easily cut, shaped, and molded, making them adaptable to different design and application requirements.

PS sheets find applications in a wide range of industries, including construction, packaging, signage, displays, model making, and arts and crafts.
