When a customer wants additional cabinet protection, why does MBA install white polyethylene wear plates and steel hopper plates instead of black rubber curtains?
MBA will install black rubber curtains if the customer insists, however most customers prefer the benefits of the white polyethylene wear plates. Black is the most common and least expensive color for rubber; that is why it is used. However, black rubber absorbs important cabinet light. In addition, the thin, flexible rubber curtains on the cabinet walls and doors are susceptible to the air and abrasive from the blast nozzle. Most rubber curtains are held in place with bolts and fender washers. The air causes the curtains to flex and the abrasive causes stress around the fender washers. It is not unusual for the curtains to tear away from the anchors and begin flapping inside the cabinet. MBA uses 3/16″ white polyethylene wear plates. The white polyethylene is resistant to wear and does not absorb light. The plates are rigid so it cannot tear free from the anchors and flap. Abrasive can get behind the rubber liners causing lifting or ballooning. For this reason, MBA offers steel hopper
