Usually polyester; some modern balls are based on urethanes instead. Older balls were hard rubber, which is also a polymer but would not be considered "plastic" by most people. There's a more dense "core" in the ball that's made of a composite material, so the ball weighs more than a solid piece of the outside plastic would.
A plastic cup is typically made of a type of polymer called polyethylene terephthalate (PET). PET is a common plastic material that is lightweight, durable, and easy to recycle.
A plastic slinky is typically made from a type of polymer called polyethylene, which is a versatile and durable material commonly used in various plastic products.
Plastic bags are typically manufactured from high density polypropylene (HDPE - plastic number 2) or low density polypropylene.
Ha Ha Ha actually we can't differentiate between plastic and polymer because plastic itself is made of polymer.
Yes, a rubber ball is typically made from synthetic polymers such as polybutadiene or polyisoprene. These polymers give the rubber its elasticity and bounce.
A bowling ball is made up of a plastic outercore
If the plastic in the ball weighs 0.05 lbs, and the ball contains nothing but the plastic, then the weight of the ball is 0.05 lbs.
A bowling ball is made from urethane, plastic, reactive resin or a combination of these materials.

Some are plastic, most are a resin type material.
Mainly wood for the lane, rubber or wood for the gutter, plastic or metal for the ball return.

plastic (polymer)
If the ball is made from a rubber based polymer, which I would assume it is due to elasticity, then it is NOT biodegradable.
