thermosettings and thermoplastics. A thermoplastic can be remelted and reused, a thermoset cannot.
I don't know, but poo does!
Plastic. Vinyl and Teflon are two of the most common plastics used.
Berry Plastics was created in 1967.
Thermosetting plastics
The main use of natural gas is for heating homes and buildings, generating electricity, and powering vehicles. It is also used as a raw material in the production of fertilizers, chemicals, and plastics.
By properties they are Thermosetting plastics and Thermoplastics
The main building block for plastics is not an element but rather a molecule that's called 'monomere' which turns into a 'polymere' by combining many molecules together (polymerisation reaction) in plastics
Paper, Plastics and Metals are the main material that can be recycled.
1 and 2 and 3
I don't know, but poo does!
Two of the earliest plastics were:Bakelite = phenol formaldehydePolyurethane = urea formaldehyde
thermoplastic plastics (recyclable)thermosetting plastics (non-recyclable)
thermoset which can withstand higher temperatures in comparison to the other type thermo plastics
PVC and ABS
It occurs when two dissimilar platics or the highly rare event that you have more than two plastics working together to accomplish a common goal.
Two significant disadvantages of using plastics are their environmental impact and health concerns. Plastics can take hundreds of years to decompose, leading to pollution in oceans and ecosystems, harming wildlife. Additionally, certain plastics can leach harmful chemicals into food and beverages, posing risks to human health.
Plastics, which are polymers plus some additives, are their main use.
