Definition

Coverstock is defined as the most outer portion of a bowling ball that makes contact with the lane. Coverstock material accounts for roughly 80% of the reaction seen on the bowling lane.

Coverstocks are made out of different types of material.

  • Plastic/Polyester
  • Rubber
  • Urethane
  • Reactive Resin
  • Particle Reactive
  • Epoxy

Each of these materials generate different amounts of friction with the bowling lane, this causing different reactions.

Plastic/Polyester

Polyester is the least aggressive coverstock available, thus reacting the least in the oily part of the lane and least on the dry portion of the lane. Plastic coverstock balls are usually reserved for situations where a bowler wants to go as straight as possible, such as spare shooting, or reserved for extremely dry lanes, where control and minimal reaction is a must. Most plastic balls do not come with a core, as having the dynamics of a core inside can be costly to create and have a very marginal benefit on the lanes. Plastic balls with a core tend to cater to a very

Rubber

Rubber is an old coverstock material from before the 1980's when Urethane was first released. Rubber offers slightly more reaction than plastic, and very similar to urethane. Drilling rubber balls can be an unpleasant and unhealthy experience. During the drilling process the rubber coverstock had the tendancy to heat up from friction due to the drill bit, partially melting the softer rubber shell, emitting a profound odor most can identify with if they've driller a rubber ball.

Urethane

Urethane began the original "power boom" most bowlers enjoy about the game now. Urethane has greater angle and ability to cover more boards than rubber or plastic coverstocks. The first urethane ball to introduce this type of coverstock was the AMF Angle. The covertock revolutionized the game, and provided the base material for reactive coverstocks that are very popular today.
