like in hockey games, and when backboards break in the Nba.

It doesn't actually turn white. The glass is designed to shatter rather than turn into large chunks which whether it is a sheet of hockey glass or a back board could cause serious damage to the players or spectators behind it. Much like auto glass, it breaks into small pieces, which can still cause some minor damage but not to the extent a large piece could cause. The reason it looks white is because the pieces of glass will rotate, spin, whatever and you can no longer see through the small pieces. If you were to pick up a small piece you could look through the two sides that were originally not attached to the rest of the glass.

Plexiglass doesn't shatter, or turn white when it breaks. Safety glass, I believe, is what you are referring to, and it doesn't turn white either. It will shatter, and is designed to break into many smaller, and lighter pieces, so not to leave any potentially dangerous large pieces to impale someone with. Plexiglass (a trade name for acrylic sheet) is used in some arenas due to it's lighter weight, will break, but I don't believe it has evolved engineering wise to a point where it will shatter into smaller pieces. When acrylic breaks, it stays in fairly large pieces prompting some arena builders to stay away from it. The plastics industry is looking further into creating a safer acrylic sheet to eliminate this problem.
Hope this helps.

All NHL arenas are mandated by law to use plexiglass. The plexiglass used in NHL rinks is manufactured by a company in St. Louis exclusively for the NHL. They have provided it to all NHL teams since 1971. Prior to 1971, there were still arenas that used regular glass around the end boards (Los Angeles Forum was the last to do this)

the white that you see is where the fractures occur withing the glass, the edges are white and so when you see the edges in the glass after it breaks, it appears white

I might be wrong, but I thought that was actually glass.
