All substances are composed of molecules, and there is also mutual attraction between molecules. Molecules are composed of substances because they have atoms, and their atoms are not single. The nucleus and its surrounding electron group are composed of electrons. The electrons have a negative charge, and the atomic charge has a positive charge. , Just like the polarity,

Just as a positively charged anode and a negatively charged cathode among the molecules, those that can be divided into anode and cathode in the molecule are called polarities. Polar molecules are called polar molecules, and non-polar ones are called non-polar to distinguish them. Polar molecules are like molecules that attract the anode and cathode like a magnet. The cohesion becomes larger and has different characteristics from non-polarity.

The following are the materials of polar rubber and non-polar rubber Introduces  Rubber Rings Manufacturer  .

Polar rubber:
Neoprene, nitrile rubber, HNBR, XNBR, fluororubber, polyurethane rubber, polyether rubber, polysulfide rubber, ACM acrylate rubber, CM/CSM rubber.

Non-polar rubber:
Natural rubber, styrene butadiene rubber, butadiene rubber, ethylene propylene rubber, butyl rubber.
