WINONA, Minn.—Anti-static properties are inherent throughout a new thermoplastic sheet developed by Engineered Sheet Products (ESP), providing permanent protection from the damaging effects of static electricity and dust, according to a press release from ESP, a division of RTP Company.

Known as PermaStat™, the compounded thermoplastic sheet exhibits consistent surface resistivity of 109 to 1011 ohms/square, offering “superior ESD protection and dust control” for OEMs and processors, according to the developer. When higher conductivity and lower surface resistance (107 to 108 ohms/square) are required, ESP also offers PermaStat Plus™ sheet.

“PermaStat sheets offer significant benefits over surfactant anti-static coatings,” explained Tom Gavinski, sales engineer for ESP, in the release. “Because they are made from thermoplastic compounds, the anti-static properties are inherent throughout the sheet. The sheet maintains ESD protection, even with scratches, wear, machining, or forming. PermaStat sheets also function well in low humidity—unlike migratory anti-static agents, which can be removed through product movement, cleaning agents, or evaporation.”

The PermaStat sheets are free of carbon-based additives and do not slough, suiting them well for dust-free environments. They are fully colorable and can be custom colored to meet specific application requirements. In addition, they contain no corrosive agents to out-gas on metal components, thereby eliminating costly pre-cleaning steps in electronic assembly operations.

Available in a variety of resin systems, including PP, PC, Acrylic, PETG, ABS, and others, PermaStat sheets can also be customized with structural reinforcements, flame retardant properties, and wear additives. They are made from compounds that comply with MIL-PRF-81705D static decay specifications, and can also be made from compounds that comply with UL94 V-O flame ratings.

PermaStat and PermaStat Plus sheets are available from ESP with full technical support from design through production.

ESP-Engineered Sheet Products (, a division of RTP Company, manufactures specialty engineered thermoplastic sheet with a focus on conductive, anti-static, thermoplastic elastomer, flame retardant, high temperature, structural reinforced, wear, lubricated, and color solutions.

RTP Company, headquartered in Winona, Minn., is a global compounder of custom engineered thermoplastics. The company has 17 manufacturing plants in the United States, Europe, and Asia. Engineers from RTP Company develop customized thermoplastic compounds in more than 60 different engineering resin systems for applications requiring color, conductive, elastomeric, flame retardant, high temperature, structural, and wear-resistant properties.
