What is the main component in glass?
silicon dioxideCommercial glass composition Such glasses are made from three main materials—sand (silicon dioxide, or SiO2), limestone (calcium carbonate, or CaCO3), and sodium carbonate (Na2CO3)..
What are the physical properties of a rubber band?
Elasticity is the mechanical property of a material to return to its original shape where Tensile Set is the amount on extension remaining after being stretched. A rubber band would have a low Tensile Set percentage. After stretched it relaxes close to, if not exactly to, its original length.
What are the physical properties of wood?
The main physical properties of wood include: color, luster, texture, macro-structure, odor, moisture, shrinkage, internal stresses, swelling, cracking, warping, density, sound – electro – thermal conductivity. Сolor, shine, texture and macrostructure determine the appearance of wood.
Why is rubber used?
Natural rubber is one of the most important polymers for human society. Natural rubber is an essential raw material used in the creation of more than 40,000 products. It is used in medical devices, surgical gloves, aircraft and car tires, pacifiers, clothes, toys, etc.
What are the properties of a good timber?
Qualities of Good TimberHardness. A good quality timber should be hard enough to resist deterioration.Strength. It should have sufficient strength to resist heavy structural loads.Toughness. It should have enough toughness to resist shocks due to vibrations. … Elasticity. … Durability. … Defects. … Fibres and Structure. … Appearance and Colour.More items…•Jun 17, 2015
What are the two types of rubber?
There are basically two broad categories into which the rubber types can be placed. These are- Natural Rubber and Synthetic Rubber. Sometimes vulcanized rubber is also taken to be a type of rubber.
What is the hardest type of rubber?
Nitrile (also known as Buna-N) is a copolymer of butadiene and acrylonitrile and one of the strongest rubber materials in applications involving oil and fuel.
How rubber is made step by step?
Natural rubber Latex is gathered from the trees by making a cut in the bark and collecting the runny sap in cups. This process is called tapping. In order to prevent the sap from solidifying, ammonia is added. Acid is then added to the mix to extract the rubber, in a process called coagulation.
What are the physical properties of glass?
The main characteristics of glass are transparency, heat resistance, pressure and breakage resistance and chemical resistance.
What is rubber and its properties?
It has excellent tensile, elongation, tear resistance and resilience. It has good abrasion resistance and excellent low temperature flexibility. Without special additives, it has poor resistance to ozone, oxygen, sunlight and heat. It has poor resistance to solvents and petroleum products.
What is rubber and its type?
Rubber is a natural polymer of Isoprene (2-Methyl -1, 3 – Butadiene). It is a linear, 1, 4 – addition polymer of Isoprene. Natural rubber has elastic properties and it undergoes long range reversible extension even if relatively small force is applied to it. Therefore, it is also known as Elastomer.
What is rubber used for?
Uses of RubberRubber moulded products are widely used industrially (and in some household applications) in the form of rubber goods and appliances.Rubber is used in garden hoses and pipes for small scale gardening applications.Most of the tyres and tubes used in automobiles are made up of rubber.More items…
What are physical properties of water?
1 Physical Agents. Physical properties of water are related to the appearance of water, namely, the color, temperature, turbidity, taste, and odor.
What is another use for rubber?
Other household rubber items include boots, raincoats, pond liners, mattresses and cushions, pillows, grips on garden tools, bathtub plugs, doorstops, earplugs, hot water bottles, aquarium tubing, faucet washers and rug backings.
What are the physical properties of vinegar?
Physical properties: Vinegar is a colorless liquid with corrosive pungent vinegar-like odor with a sour taste. Its density is 1.05 g/mL, and its melting and boiling point are 16 ºC and 118 °C, respectively. It is highly miscible in water, methanol and ethanol.

What are rubber products?
Rubber products are usually divided into three major classes: (1) tires, (2) industrial rubber goods used in motor-vehicle, aircraft, and ship construction, agricultural machine building, railroad transport, and construction, and (3) consumer goods, including footwear (the most important in this category), mats, …
How are rubber products made?
First, you have to gather your latex from the rubber trees using a traditional process called rubber tapping. That involves making a wide, V-shaped cut in the tree’s bark. … The latex from many trees is then filtered, washed, and reacted with acid to make the particles of rubber coagulate (stick together).
What is special about rubber?
Rubber can stretch and shrink. Rubber can contain gases. Rubber can fetch off lightning And/or electricity.
