Density - the degree of compactness of a substance.

Reactivity

# data[].attributes.body
the quality of being reactive or the degree to which something is reactive.

# data[].attributes.body
Polymers have a low reactivity as they contain strong intermolecular and intramolecular bonds.

# data[].attributes.body
Whilst polymers are made from readily available oil and even coal, moving carbon from long term geographical storage into the atmosphere can result in climate change.

biodegradability

# data[].attributes.body
biodegradability - the capability of a substance being decomposed by bacteria or other living organisms and thereby avoiding pollution.

# data[].attributes.body
The strength, durability, density and other physical traits of polymers can be altered

# data[].attributes.body
Plastics produce toxic gases when burnt at low temperatures to provide energy

# data[].attributes.body

# data[].attributes.body
Recyclability
convert (waste) into reusable material.

# data[].attributes.body
Density is an object's mass per unit of volume

# data[].attributes.body
Durability

# data[].attributes.body
Durability is the ability to withstand wear, pressure, or damage.

# data[].attributes.body
Can be burnt to provide energy after use.

# data[].attributes.body
Not very biodegradable as the plastics are broken down into micro-plastics which can still harm some animals.

# data[].attributes.body
Biodegradability- is the ability of organic substances and materials to be broken down into more simple substances through the action of enzymes and microorganisms

Durability

# data[].attributes.body
Durability - the ability to withstand pressure, wind and other forms of damage.

# data[].attributes.body
Are made from readily available materials - e.g. coal and oil

# data[].attributes.body
While they can be recycled, most aren't and need to be separated, resulting in landfill.

# data[].attributes.body
durability
low density
nonreactive
resistant to biological decomposition

# data[].attributes.body
light
cheap and convenient
good insulators of heat and electricity

# data[].attributes.body
some of them can't be decomposed by the environment
burning them can create lots of toxic gases
