Many things are made out of "Non Thermoplastics", which are called Thermosetting Polymers.
Basically there are two kinds of Plastics:
Thermoplastic, which are heated and injected under pressure into molds to create new items. These are plastics that get soft when heated.
And Thermosetting Polymers that are resins that are either combined with a substrate or used alone, then poured into a mold, then subjected to heat and pressure to create items or sheets. These are plastics that get hard when heated.
Things that are made from Thermosetting Polymers (Non thermoplastic): sheets of fiberglass and phenolic out of which circuit board found in computers are made from, knobs, wheels, etc.
What else can I help you with?
is a plastic a thermosetting or thermoplastic?
thermoplastic
Is HIPS plastic thermosetting?
No, HIPS (High-Impact Polystyrene) is a thermoplastic, not a thermosetting plastic. Thermoplastics can be melted and reshaped multiple times, while thermosetting plastics undergo a chemical reaction during curing that makes them rigid and non-meltable.
Is thermoplastic elastomer safe for use in food packaging?
Yes, thermoplastic elastomer is generally considered safe for use in food packaging as it is non-toxic and does not leach harmful chemicals into food.
Is thermoplastic rubber safe for use in children's toys?
Yes, thermoplastic rubber is generally considered safe for use in children's toys as it is non-toxic, durable, and flexible. However, it is important to ensure that the specific type of thermoplastic rubber used meets safety standards and regulations for children's products.
Is polypropylene a thermoplastic or a thermosetting?
It is a thermoplastic! :)
Is a ruler thermoplastic or thermosetting?
Thermoplastic
What Flammable thermoplastic material is used to make photographic film?
Celluloid
What is high density polyethylene?
HDPE is high density polyethylene used to make plastic pipe which is flexible, thermoplastic and non biodegradable. it is used in refineries for the transportation of water, gas, sewage etc.
Are thermoplastic elastomers safe for use in consumer products?
Yes, thermoplastic elastomers are generally considered safe for use in consumer products as they are non-toxic, durable, and have good chemical resistance. However, it is important to ensure that the specific type of thermoplastic elastomer being used meets regulatory standards for the intended application.
Is plastic bottles thermosetting or thermoplastic?
thermoplastic
Is Teflon thermosetting or thermoplastic?
Teflon is a thermoplastic.
What is a non thermoplastic?
A non-thermoplastic material is one that does not soften or flow when exposed to heat and instead undergoes a permanent chemical change. Examples include thermosetting plastics like epoxy resins or phenolic resins, which form irreversible chemical bonds when heated and cooled, making them resistant to high temperatures.
