Urethane casting is the process of injecting polyurethane and additive resins into a soft mold made of a silicone elastomer. The casting process is similar to injection molding but does not use hard, tooled metal molds. It is used for short-runs and low to medium volume production, which is due to the rate at which the silicone molds wear ...

Urethane is a more durable and flexible product than any plastic. While plastics do last a long time, products made of plastic will wear out before a urethane product does. They are also more likely to break, abrade, or deteriorate before urethanes will. One of the most unique aspects of urethane is the material's elastomeric ability.

The urethane balls are much more affordable to own and are also much more environmentally friendly. The urethane balls are also more lightweight than leather balls, making it easier to bowl with consistency. The urethane balls also last much longer than leather balls. This means that you'll save money and have a much longer-lasting ball.

Others will look at how many layers the ball has, but another big factor you need to consider is the cover material, which could be urethane, ionomer, or Surlyn. As a general rule, ionomer and Surlyn golf balls are cheaper and will spin less, which makes them great for beginners and high handicaps. Urethane golf balls are made for better ...

For example, unlike polyester or reactive resin bowling balls, urethane balls are well suited for dry, non-oiled lanes. Urethane doesn't absorb oil readily, so it won't create much friction. Instead, it will retain the speed and power of your throw and stay on course. Urethane balls are also great on light to medium oiled lanes, giving them ...
