ABS (acrylonitrile-butadlene-styrene) is a low-cost engineering thermoplastic that is easily machined, fabricated and thermoformed.
Is ABS Food Safe?
ABS plastic is generally considered safe for use in food-contact materials by regulatory agencies such as the FDA (U.S. Food and Drug Administration) and the EFSA (European Food Safety Authority) when it is used in accordance with their guidelines and regulations. It can be safely used in food processing and food handling operations. However, it’s important to note that the safety of ABS for food-contact applications can also depend on the specific additives, colorants, and processing methods used in its production. It’s recommended to use ABS materials that are specifically formulated and tested for food contact use, and to follow the manufacturer’s instructions for safe use and handling.
So, yes, in general, ABS is food safe for processors.
This thermoplastic material has excellent chemical, stress and creep resistance. ABS offers a good balance of impact, heat, chemical and abrasion resistance, dimensional stability, tensile strength, surface hardness, rigidity and electrical characteristics.
ABS plastic remains hard, rigid and tough even at low temperatures. It is available in fire-retardant, heat-resistant and platable grades. Impact strength varies by grade. See the chart below for ABS yield strength, Young’s modulus (ABS elasticity), tensile yield strength of ABS plastic, mechanical properties of ABS plastic, and other properties.
Most natural ABS resins are translucent to opaque, but they can be produced in transparent grades and can be pigmented to display almost any color.
This material is primarily for indoor use. General purpose grades may work for some outdoor applications, but prolonged exposure to sunlight causes color changes and reduces surface gloss, hardness, impact strength and elastic modulus. Set the chart below for details of the material properties of ABS.
As a thermoplastic, ABS material is recyclable.
