Types of plastic
- polyethylene (HDPE or LDPE) found in plastic bags and shampoo bottles
- polystyrene (PS) found in computer cases
- polypropylene (PP) found in dishwasher safe containers
- polyethylene terephthalate (PET) found in soda bottles
- polyvinyl chloride (PVC)
More generally speaking in engineering, plastics are divided into thermoplastic plastics and thermoset plastics
These are based on their properties upon reheating after the plastic is molded. Thermoplastic plastics when heated will melt whereas thermoset plastics will not melt but only burn
This is due to the way the branches of polymers coordinate. Thermoplastic plastics governed by largely van der waals forces. Thermoset plastics are crosslinked by covalent bonds
What else can I help you with?
Why are there different recycling numbers?
There are different recycling numbers on different plastics because all plastics are different. Many recycling facilities need to separate these types of plastics because they all melt at different temperatures and can be reused for different things.
What is a resin identification code?
A resin identification code is a number within a triangular recycling symbol on plastics that identifies the type of resin the plastic is made of. This code helps with sorting and recycling different types of plastics.
Can plastics be used in medical implants?
Yes, plastics can be used in medical implants. There are certain types of plastics, known as biocompatible plastics, which are specifically designed to be safe and non-toxic for use in the human body. These plastics can be used for various medical implants such as joint replacements, dental implants, and cardiac devices.
What is the chemical properties of plastics?
There are many different kinds of plastics that have many different chemical properties. However, some of the most common are chemical resistance, water reactivity, solubility, and thermal stability.
What are the different types of petrochemicals and their uses?
Some common types of petrochemicals include ethylene, propylene, benzene, and xylene. They are used in various industries for manufacturing plastics, synthetic fibers, detergents, solvents, and pharmaceuticals. These petrochemicals serve as building blocks for numerous consumer products and industrial applications.
Types of thermosoftening plastics?
Thermosoftening plastics soften and can be given any shape when hot. The different types thermosoftening plastics are Polyethylene, Polystyrene, Poly Vinyl Chloride, ABS plastics.

there is no exact amount of plastics used in america because there are many different types of plastics.
What is a M249 light machine gun made of?
Mainly different types of steel, and some plastics.
Distinguish between plastic?
There are different types of plastics named polystone, resin, vinyl, PVC and ABS.
How do you separate plastics?
You can separate plastics by color to make it easier for recycling companies. You can also separate it by the types of plastics.
What type of plastics are thermo plastics?
three types of thermo plastics are POLYETHENE.....,POLYPROPYLENE........and.......POLYVINYL CHLORIDE(PVC)
PET plastics are coded with what number?
PET plastics are coded with the number 1 within the resin identification coding system (RIC). This code helps recycling facilities identify and segregate different types of plastics for recycling efficiency.
Why are there different recycling numbers?
There are different recycling numbers on different plastics because all plastics are different. Many recycling facilities need to separate these types of plastics because they all melt at different temperatures and can be reused for different things.
