ABS Plastic Sheet: Properties, Uses, and Buying Guide

By B. Decker, Digital Content Specialist | Farco Plastics | Published: October 20, 2026

ABS plastic sheet is a tough, rigid thermoplastic made from acrylonitrile, butadiene, and styrene. It takes impact well, machines cleanly, and forms easily under heat. Standard ABS is not weatherable long term, so outdoor parts need a UV-protective cap. It is typically sold in black or white sheets from about 0.06 to 0.24 inch thick.

What Is ABS Plastic Sheet?

ABS stands for acrylonitrile butadiene styrene. It is a rigid thermoplastic that makers extrude into flat sheet for cutting, machining, and thermoforming.

ABS is a blend of three building blocks, and each one has a job:

• Acrylonitrile adds chemical resistance, hardness, and heat resistance.
• Butadiene is a rubbery phase that adds toughness, even at low temperatures.
• Styrene adds a glossy surface, stiffness, and easier processing.

The mix changes by grade. Typical ranges are 15% to 35% acrylonitrile, 5% to 30% butadiene, and 40% to 60% styrene. ABS is amorphous, so it has no sharp melting point. It softens as it heats, with a glass transition near 105 °C (221 °F).

Farco supplies ABS sheet. See the ABS product page and ABS category.

ABS Plastic Sheet Properties

Typical ABS sheet properties fall in the ranges below. Exact values change with the grade, so pull the data sheet for the sheet you plan to buy.

Source: manufacturer typical-property data. Ranges cover several grades. ASTM International publishes the test methods, such as ASTM D648 for heat deflection and ASTM D256 for Izod impact.

What the numbers mean in practice

• Impact: ABS is tough at room temperature, but cold costs you. One maker's grades fall from 5.0 to 8.0 ft·lb/in notched Izod at 73 °F to 1.4 to 4.0 ft·lb/in at −20 °F.
• Heat: Heat deflection under a 264 psi load is 170 to 190 °F. One distributor data sheet lists 160 °F as the maximum continuous service temperature. Design continuous-use parts below that number.
• Moisture: Water barely affects ABS. Sunlight does.
• Expansion: A 96-inch sheet with a coefficient of 5.0 × 10⁻⁵ in/in/°F grows about 0.24 inch across a 50 °F swing. Leave room for it in fixed installations.

Which ABS Grade Should You Buy?

ABS sheet is not one product. Makers sell several grades, and the grade decides price, impact, and finish.

Surface finish is a separate choice. Makers list smooth, matte, haircell, and calf grain textures. Stock haircell sheet is textured on one face with a smooth reverse.

UV-resistant and fire-rated grades also exist. Ask for the actual rating on the data sheet. Do not assume one.

Can ABS Plastic Sheet Be Used Outdoors?

Not without a cap. Sheet makers state it plainly: ABS is not inherently weatherable long term. Sunlight and heat cause yellowing and embrittlement through photo-oxidation.

The fix is a cap layer. A weatherable cap, laminated or co-extruded over the ABS, adds UV and chemical protection. Co-extruded ABS with an acrylic cap is sold for roofing panels and siding, boat hatches, kayaks, and golf cart and ATV parts.

If the part must also be clear, or must last for years in full sun, look at other materials. Acrylic has a reference outdoor service life of 10 to 20 years. Uncoated polycarbonate shows UV degradation in about 2 to 5 years. Our weather-resistant plastics guide covers the options.

How Does ABS Compare With HIPS, PVC, Polycarbonate, and Acrylic?

ABS sits between the entry-level and premium sheet materials. It is stronger than HIPS, and it thermoforms easily once dried.

Choose ABS when you need a tough, paintable, machinable part that forms cleanly. Choose something else in these cases:

• Low-cost indoor display or packaging: HIPS is the entry-level option. See our polystyrene sheets.
• Flat signs and displays: PVC foam board is the budget pick. See our sign substrates comparison and the LumaTek line.
• Clear, high-impact parts: Polycarbonate wins. See polycarbonate sheet.
• Clear or lit parts that live outdoors: Acrylic weathers well. See acrylic sheet.

Where Is ABS Plastic Sheet Used?

ABS shows up wherever a part needs to be tough, formable, and easy to finish.

• Automotive and transportation: dashboard components, interior trim panels, and protective casings.
• Consumer goods and appliances: appliance housings, electronics enclosures, toys, luggage, and refrigerator and ice bin liners.
• Industrial: machinery covers, prototypes and tooling, storage and shipping containers, pallets and dunnage, and medical carts and equipment.
• Outdoor, capped grades only: boat hatches, kayaks, camper and golf cart parts, pool steps, and pump covers.

How Do You Cut, Form, and Bond ABS Sheet?

ABS is forgiving to fabricate. That is a big reason shops choose it.

• Cutting and routing: Extruded ABS cuts, routes, and fabricates with common woodworking tools.
• Bonding: It solvent-bonds easily. It can also be painted or bonded with adhesive.
• Thermoforming: ABS forms well under vacuum. Formech lists a vacuum-forming range of 150 to 180 °C (302 to 356 °F). It also says ABS must be dried first and lists 90 minutes per millimeter of thickness. Follow your sheet maker's drying guidance.
• Deep draws: Some extruded grades are sold for deep-draw thermoforming because of their high melt strength.
• Machining: Machine-grade sheet is formulated for machining and offers enhanced dimensional stability.

Watch your cleaners. Ketones such as acetone, esters, and chlorinated solvents attack ABS. Alcohols are a poor match too. ABS holds up to aqueous acids, alkalis, and oils. Concentrated sulfuric and nitric acids attack it.

What Sizes and Thicknesses Does ABS Sheet Come In?

Stock sizes differ by maker, so treat these as typical, not a Farco stock list.

• Standard sheet size: 48 × 96 inches.
• Black stock thicknesses: 0.056, 0.090, 0.118, 0.177, and 0.236 inch.
• White stock thicknesses: 0.090, 0.118, 0.177, and 0.236 inch.
• Maker ranges: Sheet is commonly made from 0.060 to 0.236 inch. One maker's custom runs go from 0.020 to 0.375 inch, up to 120 inches wide, with a 5,000 lb minimum order.

Colors are usually black or white, with custom colors by request. Ask your Farco location what is on the shelf today.

How to Choose the Right ABS Sheet

Work through these five questions before you order.

1. Where will it live? Indoors, a standard grade is usually enough. Outdoors, specify a capped, UV-resistant grade.
2. What temperature range will it see? Cold lowers impact. Keep continuous heat at or below 160 °F.
3. How will you fabricate it? Machining points to machine grade. Deep thermoforming points to a thermoforming grade.
4. What finish do you need? Pick smooth, matte, or textured, and decide whether one face or both must look good.
5. Do you need paperwork? Ask for the data sheet, plus any flammability rating or FDA and NSF letter you require. Some makers offer FDA- and NSF-compliant ABS on request.

Frequently Asked Questions

What is ABS plastic sheet made of?

ABS plastic sheet is made from acrylonitrile, butadiene, and styrene. Together they form a tough, rigid, amorphous thermoplastic that is extruded into sheet.

Is ABS plastic sheet waterproof?

ABS resists water well. It absorbs only 0.3% to 0.5% of its weight in 24 hours (ASTM D570). Sunlight, not water, is the bigger risk outdoors.

Can ABS plastic sheet be used outdoors?

Only if it is capped or otherwise UV-protected. Standard ABS yellows and turns brittle in sunlight, and makers say it is not inherently weatherable long term. Acrylic-capped, co-extruded sheet is the outdoor option.

How hot can ABS plastic sheet get?

Plan for 160 °F or less in continuous use. Heat deflection under a 264 psi load is 170 to 190 °F, and the glass transition is near 221 °F. ABS softens as it heats rather than melting at a set point.

How do you cut and bond ABS plastic sheet?

Cut and route ABS with common woodworking tools, and join it with solvent cement or adhesive. Ketones such as acetone dissolve ABS, so keep them off finished faces.

Is ABS plastic sheet food safe?

Not by default. Some makers offer FDA- and NSF-compliant ABS on request. Ask for the compliance letter for the exact grade you plan to use.

What is the difference between ABS and HIPS?

ABS is stronger and costs more. HIPS is the entry-level option with moderate strength. ABS needs drying before thermoforming, and HIPS does not.

What thicknesses does ABS plastic sheet come in?

Sheet is commonly made from 0.060 to 0.236 inch thick, with custom runs from 0.020 to 0.375 inch. A standard sheet is 48 × 96 inches. Ask your Farco location for current stock.

The Bottom Line

ABS plastic sheet is the practical choice for tough, formable, machinable parts that live indoors or wear a UV cap. Match the grade to the environment, confirm the numbers on the data sheet, and keep solvents away from finished faces.
