Rubber Grommet

Rubber grommets are any variation of eyelets or rings which are used as insulation devices. The term "grommet" had its origin in the garment industry and used as a type of fastener. Today, "grommet" has become an industrial standard term for cable management and modular wiring systems. Grommets are eyelets that are used to strengthen or protect an opening. They are also used to insulate and protect an object passing through an opening. They are inserted into a hole in a mechanical part to prevent grounding, chaffing or mechanical grounding. Rubber grommets are widely used to ensure safety and flexibility in the cable management system.

Types of rubber used to make grommets

• Butyl rubber or isobutylene isoprene elastomer
  • This rubber is resistant to water, steam, alkalis, and oxygenated solvents.
  • It has low gas permeation.
  • It is capable of providing both high-energy absorption (dampening).
  • It has good hot tear strength.
• Nitrile and styrene butadiene rubber (SBR)
  • This rubber is used with most oils, hydraulic fluids.
  • A variety of proprietary compounds are available for specific applications

         Applications
        Grommets have a wide range of applications:

• They are found in shoes, clothing, corsets, curtains, leather, and other fabrics. Grommets that are small in size are called eyelets and are used in clothes.
• Surge protectors, fax/modem lines, electrical wiring outlets and computer cables can be organized properly by using large oval and rectangular grommets.
• Grommets are also used on commercial tarp which is used to cover outdoor furniture, woodpiles or boats, cars etc.
• Cable management means managing large amounts of cabling under floors and this is done by using grommets.
