Properties of material

Ecological

Biodegadable

· Biodegradable polymers are a special class of polymer that breaks down after its intended purpose by bacterial decomposition process to result in natural byproducts such as gases (CO2, N2), water, biomass, and inorganic salts. ... Their properties and breakdown mechanism are determined by their exact structure

Toxic

A chemical property is a property of a substance that is observed when a substance under goes a chemical change. ... Toxicity, or the toxic and/or poisonous attributes of a substance. Flammability, which refers to whether or not a substance will burn

Recycable

Recycling is the process of converting waste materials into new materials and objects reducing: energy usage, air pollution (from incineration), and water pollution (from landfilling).

Toughness and brittleness is the ability of a material to absorb energy and plastically deform without fracturing.

Technological

Resilience

resilience is the ability of a material to absorb energy when it is deformed elastically, and release that energy upon unloading.

Elasticity/Plasticity

Elasticity and plasticity describes the deformation of a (solid) material undergoing non-reversible changes of shape in response to applied forces

Malleability/Ductility

Malleability and ductility are the ability of a solid to bend or be hammered into other shapes without breaking.

Toughness/Brittelness

Hardnes

Resistance of a material to deformation, indentation, or penetration by means such as abrasion, drilling, impact and scratching.

Chemical

Subtema

Corrsion

Corrosion involves the deterioration of a material as it reacts with its environment. Corrosion is the primary means by which metals deteriorate. Corrosion literally consumes the material reducing load carrying capability and causing stress concentrations.

Oxidation

Oxidation is the loss of electrons. It happens when an atom or compound loses one or more electrons. Some elements lose electrons more easily than others.

Physycal

Mechanical

strength

Shear, torsion, tension, compresion and flexion.

Mechanical properties are also used to help classify and identify material. The most common properties considered are strength, ductility, hardness, impact resistance, and fracture toughness.

Optical

Transparent

When the light can pass perfectly

Translucent

When the light can pass a little bit

Opaque

When the light can't go through

The optical properties of a material define how it interacts with light.

Thermal

Heat is the transfer of energy from a one object to another due to a difference in temperature. Heat can be measured in joules or calories.

Welding

Flexibility

Expansion/Contraction

Electricity is a type of energy that can build up in one place or flow from one place to another. When electricity stays in one place it is known as static electricity; electricity that moves from one place to another is called current electricity.

Electrical

Semiconductivity

Insulation

Conductivity

Density

Density is how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass).
