When was acrylonitrile butadiene styrene invented

Dehydrogeneration processes are used extensively to produce aromatics and styrene in the petrochemical industry. There are two types: One is for the extrusion of shapes and the other is a thermoplastic used for molded products. ABS composites are usually half styrene with the rest balanced between butadiene and acrylonitrile.

ABS blends well with other materials such as polyvinylchloride, polycarbonate, and polysulphones. These blends allow for a wide range of features and applications. Although it was not useful in that application, it did become widely available for commercial applications in the s.

Today ABS is used in a diverse group of applications including toys. Also molding at high temperatures improves the gloss and heat-resistance of the material while molding at low temperatures results in high impact resistance and strength. The different amounts so f each monomer can be added to the process to further vary the finished product. The versatility of ABS plastic properties contributes largely to its popularity across several industry sectors.

From computer keyboard keys to LEGO, products made from ABS can be found all around the world in multiple domestic, commercial and specialist settings. The acrylonitrile in ABS provides chemical and thermal stability, while the butadiene adds toughness and strength.

The styrene gives the finished polymer a nice, glossy finish. ABS has a low melting point, which enables its easy use in the injection moulding process and 3D printing. It also has high tensile strength and is very resistant to physical impacts and chemical corrosion, which allow the finished plastic to withstand heavy use and adverse environmental conditions. ABS can be easily moulded, sanded and shaped, while its glossy surface finish is highly compatible with a wider range of paints and glues.

ABS plastics takes colour easily, allowing finished products to be dyed in exact shades to meet precise project specifications. As well as its uses in computer keyboard components and LEGO bricks, ABS is commonly used to make plastic face guards for wall sockets and protective housing for power tools.

It is commonly used in the automotive field too, for items such as plastic alloys and decorative interior car parts. In the construction industry, ABS comes into its own in the manufacture of plastic tubing and corrugated plastic structures.

Look for blue edges around the yellow flame, indicating it's ABS plastic. Notice a pungent smell if the plastic is ABS. ABS plastic has a very strong, acrid smell when it burns. Acrylonitrile Butadiene Styrene, often abbreviated as ABS , is an opaque engineering thermoplastic widely used in electronic housings, auto parts, consumer products, pipe fittings, lego toys and many more.

Determining if materials can be used safely for their intended use is one of the responsibilities of the U. It may be used outdoors if the pipe contains pigments to shield against ultraviolet radiation, or jurisdictions may require the pipe to be painted with water-based latex paint for outdoor use. ABS Acrylonitrile butadiene styrene is a petroleum-based, non-biodegradable plastic.

And it's inherently more toxic plastic than PLA. Plastic is basically a general term! There are various types of plastics differentiated in various manner! And if you mean normal plastic as Polyethylene then its a general plastic. In this process, high purity plastics are separated by water streams from a mixture of plastics.

ABS production may be dangerous in vapor form for workers. But while the individual ingredients aren't good for you, it's unlikely you will encounter them because ABS doesn't break down easily or leach anything into food, water or soil. Plasticizers like phthalate aren't required, so there are none to be released. ABS has a tensile strength of about psi, while polypropylene has a tensile strength of about psi. These include domestic appliances, telephone handsets computer and other office equipment housings, lawn mower covers, safety helmets, luggage shells, pipes and fittings.

Because of the ability to tailor grades to the property requirements of the application and the availability of electroplatable grades ABS is often found as automotive interior and exterior trim components. Automotive construction places particularly high requirements on the materials used. Under extreme stresses they have to be dimensionally stable and must not warp, even when faced with great temperature variations.

Electrical and eletronics industries increasingly require surfaces which are not only highly scratch- and wear-resistant but also decorative and easy to maintain. Attractive products with elegant design and high quality create a feeling of well-being at home and in the office. ABS can create exciting and varied color schemes.

Grades can also be electroplated, emboss-stamped or metallized. Depending on the molding equipment used. Surfaces can be matt, glossy or satin. British Plastics Federation.
