thermosettings and thermoplastics. A thermoplastic can be remelted and reused, a thermoset cannot.
I don't know, but poo does!
thermoplastics and thermosetting plastics thermoplastics go soft when exposed to heat thermosetting plastics set (harden) when exposed to heat only thermoplastics are recyclable
Plastic. Vinyl and Teflon are two of the most common plastics used.
Berry Plastics was created in 1967.
Thermosetting 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.
The main uses for coal are Fuels, Plastics and Electricity
1 and 2 and 3
I don't know, but poo does!
Two of the earliest plastics were:Bakelite = phenol formaldehydePolyurethane = urea formaldehyde
Two companies that specialize in testing plastics in the United States are Instron and Intertek. They test plastics for specific industries such as medical, aerospace and cars.
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.
