PEX, or cross-linked polyethylene, alters the properties of polymer by creating a network of covalent bonds between polymer chains during the cross-linking process. This structure enhances the thermal stability and resilience of the material, preventing it from melting and allowing it to retain its shape when heated. As a result, PEX exhibits improved resistance to deformation and better performance under temperature fluctuations compared to non-cross-linked polyethylene. This makes PEX suitable for applications like Plumbing and heating systems where shape retention is crucial.

Melting sugar is an example of a?
physical change. When sugar is heated, it changes from a solid to a liquid state without changing its chemical composition.
Are polymer malleable?
Polymers can exhibit malleability, but this property varies depending on their structure and composition. Thermoplastic polymers, for example, can be heated and reshaped multiple times, making them malleable. In contrast, thermosetting polymers harden permanently after curing and are generally not malleable. Overall, the malleability of a polymer depends on its specific type and the conditions applied.
What is thermoplastic?
Thermoplastic is a polymer that can remelted and remolded many times.Thermoplastic is a polymer resin based plastic that softens/melts when heated.Thermoset-plastic is a polymer resin based plastic that polymerizes and/or crosslinks when heated, hardening it. If heated more it just chars.
Is forms of gas when heated a physical or chemical property?
The formation of gas when a substance is heated is generally considered a physical change, as it often involves a change in state (like from liquid to gas) without altering the substance's chemical composition. However, if the heating causes a chemical reaction that produces gas (like combustion), it is a chemical change. Thus, whether it is a physical or chemical property depends on the context of the reaction.
Does talc change color if heated?
Talc don't change the color if heated.
Is polyvinyl chloride thermoforming or thermosetting?
Polyvinyl chloride (PVC) is a thermoplastic polymer, which means it can be heated and molded multiple times without undergoing a chemical change. This property makes PVC suitable for thermoforming processes where it is heated and shaped into desired forms.
When producing a different gas when heated what property is it?
That would be a chemical property demonstrated by a chemical change.
When iron becomes red-hot when heated is that a chemical or physical property?
No, it is a chemical change Iron turns green means it is oxidized to ferrous (Fe+2) state.

Is water heated and changed to steam a physical or chemical change or both?
physical only, you are only changing its state, not its composition.
Give an example of a reversible change?
An example of a reversible change is an ice cube meting into water and then changing back to an ice cube again if frozen. Another is chocolate melting when heated and changing back to a solid when cooled.
