Wafer Cushion Foam Discs – Antistatic Foam Protection for Semiconductor Wafers

Malaster’s Wafer Cushion Foam Discs provide advanced cushioning and ESD protection for semiconductor wafers, substrates, and other sensitive electronic components during storage, handling, and transport. Designed for contamination-sensitive environments, these antistatic foam discs help reduce the risk of surface damage, particle transfer, abrasion, and electrostatic discharge.

Available in standard wafer diameters from 2″ through 12″, along with square and rectangular formats for specialized applications such as solar wafers and custom substrates, Malaster Wafer Cushion Foam Discs are manufactured using carefully selected antistatic foam materials engineered for semiconductor and electronics packaging applications.

This category includes two specialized foam material options designed to support different cushioning and protection requirements.
