- Once 'set' these plastics cannot be reheated to soften, shape and mould.
- Thermosetting Plastics are made up of lines of molecules which are heavily cross linked. It creates a rigid molecular structure.
- They may be heated the first time and shaped but they become permanently stiff and solid.
- Unlike thermoplastics, they retain their strength and shape even when heated.

How does thermoplastic material differ from a thermosetting material?
Thermoplastic and thermoset materials both fall under the broad category of Polymers. The biggest difference between a thermoplastic and thermoset is that a thermoplastic can be recycled. Whereas a thermoset irreversibly cure. Thermoplastic: PE, PP, PVC. Thermoset: Bakelite, Epoxy.
Are cells in a tissue similar or dissimilar?
They are similar in origin but may differ from structure.
How does the density differ between a glass and a plastic cup that have almost exactly the same volume?
Higher molecular interaction force contribute to higher density. In additional, higher molecular weight give tendency to higher density at same intermolecular force. Even plastic had different density, some plastic is lighter than water but some can be twice heavy, PVC for example.
How does the basic structure of a steroid differ from other macromolecules such as carbonhydrates?
I have no freaking clue how and if you do you are a nerd!!
How does the usage of milk plastic differ from normal plastic?
Milk plastic is a biodegradable plastic made from casein protein found in milk while normal plastic is made from petrochemicals. Milk plastic is more environmentally friendly as it is biodegradable, whereas normal plastic is not easily biodegradable and contributes to plastic pollution. Milk plastic has a shorter life span compared to normal plastic but is a better alternative for single-use or short-term applications.

What is the difference between RTP pipe and RTR pipe?
RTP (Reinforced Thermoplastic Pipe) and RTR (Reinforced Thermosetting Resin Pipe) differ primarily in their materials and applications. RTP is made from thermoplastic materials that are reinforced with fibers, offering flexibility and resistance to corrosion, making it suitable for transporting fluids in various industries. In contrast, RTR is composed of thermosetting resins reinforced with materials like fiberglass, providing higher temperature and pressure resistance, which makes it ideal for applications like chemical and wastewater transportation. Ultimately, the choice between RTP and RTR depends on the specific requirements of the application, including temperature, pressure, and chemical exposure.
Where does plastic come from?
Thermoplastic, also known as a thermosoftening plastic,[1][2] is a polymer that turns to a liquid when heated and freezes to a rigid state when cooled sufficiently. Most thermoplastics are high-molecular-weight polymers whose chains associate through weak Van der Waals forces (polyethylene); stronger dipole-dipole interactions and hydrogen bonding (nylon);[3] or even stacking of aromatic rings (polystyrene). Thermoplastic polymers differ from thermosetting polymers (e.g. phenolics, epoxies) in that they can be remelted and remoulded. Many thermoplastic materials are addition polymers; e.g., vinyl chain-growth polymers such as polyethylene and polypropylene; others are productions of condensation or other forms of polyaddition polymerisation, such as the polyamides or polyester.

Why array is differ from structure?
An array is an aggregate of the same type. A structure is an aggregate of different types.
What are the key differences between TPR and TPE materials, and how do these differences impact their performance in various applications?
Thermoplastic rubber (TPR) and thermoplastic elastomer (TPE) materials differ in their chemical composition and properties. TPR is a blend of rubber and plastic, offering good flexibility and durability, while TPE is a versatile material with a softer feel and better resistance to chemicals and weathering. These differences impact their performance in various applications, with TPR being more suitable for applications requiring toughness and abrasion resistance, while TPE is preferred for applications needing flexibility and resistance to harsh environments.
