Businesses in the rubber and plastic category make, process or supply products and materials made from these substances. Rubber products can include seals, gaskets, hoses, belts, flooring and vibration-control components. Plastic products range from packaging, containers and household items to sheets, rods, pipes and parts for machinery, vehicles or electrical equipment. Some businesses specialise in particular materials, production methods or industries, while others supply a wider range of goods. Typical services include moulding, extrusion, casting, cutting, machining, welding and assembly. Customers may be able to request components made to drawings or specifications, as well as standard items and raw materials for further manufacture. Suppliers can advise on material grades and properties such as flexibility, strength, resistance to chemicals or suitability for outdoor use.
