- Consistent surface resistivity of 109 – 1011 ohms/square
- Anti-static properties inherent throughout the sheet
- Free of carbon-based additives
Engineered Sheet Products (ESP), a division of RTP Company, has developed a thermoplastic sheet with anti-static properties inherent throughout, providing permanent protection from the damaging effects of static electricity and dust.
Consistent surface resistivity of 109 – 1011 ohms/square
Marketed under the name PermaStat sheet, this compounded thermoplastic sheet features consistent surface resistivity of 109 to 1011 ohms/square, making them suitable for OEMs and processors who require best possible ESD protection and dust control. In case higher conductivity and lower surface resistance (107 to 108 ohms/square) are required, the company also offers PermaStat Plus sheet.
Anti-static properties inherent throughout the sheet
PermaStat sheets offer significant benefits over surfactant anti-static coatings. As 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. The sheets also function well in low humidity, unlike migratory anti-static agents, which can be removed through product movement, cleaning agents, or evaporation.
Free of carbon-based additives
The sheets are free of carbon-based additives, and do not slough, making them suitable for dust-free environments. They are fully colorable. In addition, they contain no corrosive agents to out-gas on metal components, thereby eliminating costly pre-cleaning steps in electronic assembly operations.
Based on various resin systems, incl. PP, PC, Acrylic, PETG, ABS
PermaStat sheets are available in a variety of resin systems, including PP, PC, Acrylic, PETG, ABS, among others. The sheets can also be customized with structural reinforcements, flame retardant properties, and wear additives.
