Differences in Hypalon & PVC

Hypalon is chemically known as chlorosulfonated polyethylene. It is a synthetic rubber with excellent resistance to oil, temperatures and many other adversities. It has outstanding dielectric qualities and has immense color stability. PVC is chemically Poly Vinyl Chloride and is a thermoplastic vinyl polymer. These two polymers are resistant to both water and fire and therefore, both Hypalon and PVC find applications in many areas.

Basic Differences Between Hypalon and PVC

  • The basic difference that exists between PVC and Hypalon is that of quality. Poly Vinyl Chloride is used in the manufacture of cheap vessels and cannot compete with high quality Neoprene fabrics such as Hypalon, which is highly resistant even against UV rays. Hypalon is of a superior strength and endurance than PVC, though the latter is far cheaper. Thus, both cost and quality influence the demand for the products made out of Hypalon or PVC.

Differences on the Basis of Mechanical Properties

  • PVC and Hypalon have different mechanical properties. The defect of nicks or cuts occurring in rubber upon the application of tension is called a tear. The resistance to this resistance is greater in Hypalon than in PVC. The wearing of any surface due to certain mechanical actions, like erosion, scrapping or rubbing, is called abrasion and the resistance to this process under dynamic contact to an abrasive surface is called abrasion resistance. Resistance to abrasion is also greater in Hypalon.

Differences on the Basis of Chemical Properties

  • Hypalon offers good resistance to gasoline, diesel and cleaning solvents, whereas PVC can't sustain contact with them and gets dissolved. PVC provides fair resistance to grease, oils and tar derivatives but Hypalon offers a much greater resistance to these lower solvents.

Differences on the Basis of Bonding

  • In the case of PVC, there can be two methods of bonding, which include heat welding and usage of glue. The glue used for these purposes is heat deactivated. So glue failure at extreme heat conditions and in the tropics could be a matter of concern. Heat welding or thermo-welding is done using a special type of welding machine. Hypalon, being a synthetic rubber, is bonded using a special type of glue which is not heat deactivated.
