Plastics include a wide range of materials, but can be generally categorized as synthetic polymers produced in film, fiber, or resin form. They tend to be more malleable than most metals, and are considered easier to deform. There are many types of plastics, such as silicones, polyurethanes, acrylics, thermosets, and thermoplastics, each with their own distinct set of properties. In addition, there are numerous proprietary and special-purpose plastics developed for specific applications. Plastics are used for a broad range of manufacturing purposes to create either plastic-based products and components, or compound materials.
Like plastic, rubber is a polymer substance that can be industrially synthesized, and can also occur naturally, as latex. Its chief property is elasticity, which allows it to undergo a great deal of stress without deforming. Natural rubber has weak temperature resistance, but through the process of vulcanization, which is a type of chemical heat treatment, it can be made considerably more durable and resistant to deteriorating effects. Rubber is used to create a large number of common products, such as tires, tubing, and gloves.
