Introduction

Electrostatic dissipative (ESD) polystyrene sheet coated with metal and plastic mixture that prevents static electricity from being generated on the plastic sheets. Anti-static ESD sheet’s coating is permanent and therefore is not affected by humidity as temporary topical anti-static coatings. In addition to its anti-static properties, it has superior impact and chemical resistance. Compared with conductive materials, static dissipative materials can make charge flow to the ground or other conductors in a more controlled and slow manner.

ESD (electrostatic discharge) materials

Material	Surface resistance (Ω/sq)	Characteristic
Conductive	103 to 105	Conductive materials have low resistance, so electrons can easily flow through the surface or inside of these materials. The charge will flow to the ground or another conductive object in contact with the material.
Static dissipation	105 to 109	Compared with conductive materials, static dissipative materials can make charge flow to the ground or other conductors in a more controlled and slow manner.
Anti-static	109 to 1012	Anti-static materials can inhibit friction and electricity generation.

Applications

• Hard Disk Manufacturing

Today’s hard disk manufacturing industry has the most sophisticated and sensitive electronic components in the electronics industry, which require clean and continuous ESD protection. This product is used for the packaging, turnover and storage of hard disk heads and other precision components;

• Semiconductor manufacturing

The semiconductor industry has more stringent requirements for cleanliness than ESD protection in the process of handling wafers and disk drive media. As IC circuits continue to shrink, ESD protection is becoming more and more important. This product is used in the turnover and storage of chips and disk drive media;

• Electronic product assembly and packaging

Since electronic products have already received a lot of ESD protection before they are assembled and packaged, in general, the requirements for ESD can be slightly reduced, and permanent static dissipation performance is required. This product is used to handle and transport electronic components, circuit boards and other components.
