Quoted from Breger1:
Can someone explain the theory behind playfield rubbers? titans, superbands, etc. I've always just stuck with what's in the machine. Specifically durability/longevity, difference in bounce/ball travel/playability. Or a link if posted in forum elsewhere. I have 7 newer era machines and before making a big financial investment it would be nice to know, as I've always ignored it and just played my games.
Super-Bands are made of polyurethane, and were the original non-rubber bands and rings. They are made in the United States (Cranberry Township, PA). Polyurethane is more durable than rubber or silicone. Super-Bands are translucent and come in 9 colors. Super-Bands are available from Marco, Cointaker, and Pinball Life.
Titans are silicone. Not sure if they are made in the U.S. or overseas. Silicone is generally not as durable as polyurethane.
Rubber quality varies rather dramatically between manufacturers.
Some people prefer the look and feel of rubber. Others prefer polyurethane or silicone.
