What is a material transmits some of the light that reaches it?
A material that transmits some of the light that reaches it is called a transparent material. These materials allow light to pass through them, making them see-through to varying degrees depending on their properties. Glass, water, and clear plastics are common examples of transparent materials.
How can plastic be harder than metal?
Some types of plastics, such as plastics reinforced with fibers or fillers, can have higher strength and hardness than certain types of metals. This is achieved by manipulating the molecular structure of the plastic material to enhance its mechanical properties, making it harder than some metals. Additionally, the specific properties, such as flexibility and weight, can also affect the overall perception of hardness when comparing plastic to metal.
What materials do you need to make it bounce?
To make a material bounce, you would typically need a material with elasticity and resilience. Rubber, for example, is a common material used for bouncing due to its ability to deform and then return to its original shape. Other materials with similar properties, such as certain plastics or foam, can also be used for bouncing.
What type of material that can expand?
Certain types of materials, such as rubber, foam, and certain plastics, are known to exhibit expansion properties when subjected to heat or pressure. These materials have the ability to stretch or increase in size when specific conditions are met.
What are the physical properties of nonmetallic materials?
Nonmetallic materials generally have low electrical conductivity, low melting and boiling points, and are brittle in nature. They may also exhibit properties such as being transparent, lightweight, and having low thermal conductivity. Examples include ceramics, plastics, and rubber.
What chemical and physical properties of plastic make it a perfect material as substitute to other thing?
Some examples: - plastics have a very low density - plastics are not corroded - platics are easily machined - plastics are non-corrodable
What goes into plastics manufacturing?
Plastics are usually synthetic organic polymers. The first step to manufacturing plastics is to get the materials. Step 2 is to synthesize the polymer. Step 3 involves compounding the polymer into a material that can be used and step 4 involves shaping the plastic into it's form.
When did plastics manufacturing begin to rebound?
In the early 2000s, plastics manufacturing began to rebound from the slump begun in the mid-1990s.
What is inert filler?
Inert filler is a substance added to a material or product to increase its bulk or volume without significantly altering its properties. Inert fillers are chemically stable and do not react with other materials in the product, serving mainly as a cost-effective way to adjust the physical characteristics of the material. They are commonly used in industries such as plastics, construction, and cosmetics.
What is the difference between polysaccharides and plastics?
Polysaccharides are natural carbohydrates made up of sugar units, whereas plastics are synthetic polymers derived from petroleum products. Polysaccharides are biodegradable and eco-friendly, while plastics are non-biodegradable and can persist in the environment for a long time, causing pollution.
What are the physical and chemical properties of a computer?
The physical properties of a computer include its size, weight, shape, and material composition. Computers are typically made of materials such as plastic, metal, and silicon. The chemical properties of a computer refer to the elements and compounds present in its components, such as silicon chips, copper wiring, and various plastics. Additionally, computers utilize chemical reactions within their components, such as those that occur in batteries or semiconductor materials.
How is ammonia used in various industries?
Ammonia is used in various industries as a fertilizer for agriculture, in refrigeration systems for cooling, in cleaning products for its disinfectant properties, and in the manufacturing of plastics and explosives.
What are the names of the two main gropes of plastics?
By properties they are Thermosetting plastics and Thermoplastics
Why is barium sulfate used in plastics?
Barium sulfate is used in plastics as a filler to improve the material's density, stiffness, and flame retardant properties. It also helps to enhance the plastics' resistance to heat and chemicals, making the final product more durable and suitable for various applications.
What is the advantage of using plastics?
Plastics offer advantages over metal in weight, manufacturing costs, and corrosion resistance.
What has the author Bill Fry written?
