2011-11-04 · 2.2. Effect of chain polarity. Polymers can be polar or non-polar. This feature affect significantly the dielectric properties. Examples of polar polymers include PMMA, PVC, PA (Nylon), PC while non-polar polymers include PTFE (and many other fluoropolymers), PE, PP and PS.
Polymer composite materials with hierarchical porous structure have been advancing in many different application fields due to excellent physico-chemical properties. However, their synthesis continues to be a highly energy-demanding and environmentally unfriendly process. This work reports a unique …

It is the most widely used plastic in the world, being made into products ranging from clear food wrap and shopping bags to detergent bottles and fuel tanks. The physical and chemical properties of polymers vary widely, based on their monomers, structures, and additives. Among the other properties that can be modified based on these factors include solubility in H 2 O and other solvents, melting point, flammability, color, hardness, transparency, film thickness, wetability, surface friction, moldability, and particle size—the list goes on.

Plastics are semi-organic materials that come from oil or petroleum. They are routinely labeled as polymers, as they are comprised of polymers. Plastics are produced by condensation and addition polymerization reactions. They are classified either as thermosetting polymers or thermoplastic polymers.

Plastics are semi-organic materials that come from oil or petroleum. They are routinely labeled as polymers, as they are comprised of polymers. Plastics are produced by condensation and addition polymerization reactions. They are classified either as thermosetting polymers or thermoplastic polymers. Thermosetting polymers solidify into a Gore-Tex is a brand of expanded PTFE (ePTFE), a material incorporating a fluoropolymer membrane with micropores. The roof of the Hubert H. Humphrey Metrodome in Minneapolis, US, was one of the largest applications of PTFE coatings.
