A:Corrugated Plastic “Coroplast”

Durable because it is water proof and resistant to stains and most chemicals. At regular temperatures most oils, solvents, and water have no effect, allowing it to perform under adverse weather conditions or as a product component exposed to harsh chemicals. Wide range of colors. 4mm is a common thickness; 10mm is very heavy and rigid. Coroplast is a popular brand.

Foam Core
Extruded polystyrene foam core laminated on both sides with heavy white or black smooth coated paper. Designed for interior mounting applications requiring rigid, lightweight, and relatively inexpensive material. Typically, foam core is used for short-term usage as it dents readily and does not hold up well to certain glues, such as superglue and some paints.

Ultra Board
Heavy-duty, all-plastic panel that features a litho-grade, high-impact polystyrene surface for permanent displays and signs. Ultra Board is designed primarily for interior use, but can be used outdoors, and it is durable. Dent-resistant styrene liners are secured to the foam center with a bond that keeps the panel flat and rigid. Moisture does not penetrate.

Solid or corrugated plastic core with aluminum laminated to both surfaces. Extremely flat surface that will not warp or distort. Excellent durability in outdoor applications. Alumalite, Alumacor, Dibond, and Omega-bond are popular brand names.

Extruded high impact material used primarily as an indoor panel or for outdoor usage up to 1 year.

Expanded PVC
Expanded PVC is lightweight, rigid board of moderately expanded closed-cell polyvinyl chloride (PVC). Low gloss matte finish. Will not rust, rot, peel, or absorb water. Suitable for display, exhibit, interior, or exterior signage and for photo mounting. Soften at about 150*F. This means that you can easily heat up thin (3mm or thinner) pieces and mold as needed. Sintra is popular brand name.

Magnetic Sheeting
Permanent magnetic sheet used primarily in vehicle magnetic signs. Vehicle magnetic signs are typically .030″ thick and 18″ x 24″. However, the largest magnetic sheet available is 24″ x 50″.

Sign board
Exterior grade wood products with a variety of aluminum, vinyl, or enamel surfaces. Excellent for exterior signage.

Lightweight, high optical quality, high impact strength, and excellent weather ability. Ideal for backlit signage.

Polycarbonates are Lightweight, high impact strength and excellent weather ability. They come in clear and white. Primarily known by the trademarked names Lexan, Makrolon, Makroclear and are a particular group of thermoplastic polymers. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications. Ideal for backlit signage.
