What is Polystyrene?

Polystyrene (PS) is a synthetic polymer product that comes in foam or solid form. It is one of the most common thermoplastic materials in the world. Reschcor extrudes solid or rigid PS. With an understanding of your application, we can suggest specific grades of either General-Purpose Polystyrene (GPPS) or High-Impact Polystyrene (HIPS). Each has unique properties that should be taken into consideration when deciding which one is best for your project and end-user.

Polystyrene Properties

General-Purpose Polystyrene (GPPS), sometimes referred to as Crystal PS comes in water clear and slightly blue tints. It has a glass-like clarity suitable for transparent packaging, medical, optics, and consumer applications. It has low impact strength but is better for use in higher heat applications.

High-Impact Polystyrene (HIPS), is produced with rubber additives and has much better impact strength. In its natural state, it is opaque in appearance. HIPS is often specified for low strength, low heat structural applications where low cost, impact strength, and machinability are required. Due to the durable nature of HIPS, it is often used in signage, barriers, display materials, appliances, automotive, and packaging.


Reschcor extrudes HIPS in a variety of profiles used for signage, shelving, trim, and tubing.
