PELESTAT/PELECTRON Anti Static Agent

PELESTAT/PELECTRON -Anti Static Agent or Additive

PELESTAT and PELECTRON are Inherently Dissipative Polymers (IDP) which function as permanent antistatic additives when added to thermoplastic compounds. They are block copolymers which combine the static dissipation effectiveness of polyethyleneoxide(PEO) with the physical properties of either polypropylene or polyamide. The performance of PELESTAT/PELECTRON is superior to other antistatic additives for these reasons:

  • Permanent Anti Static Performance, Effective Immediately, Lasts Forever.
  • Protects against electrostatic discharge.
  • Will Not Wipe or Wash Off.
  • NOT Dependent of Relative Humidity – Works in DRY Environments
  • Light Color – Can be Used in Colored Compounds.
  • Minimal Effect on Compound Physical Properties
  • No Particulate Contamination of Cleanroom Environments
  • Excellent Uniformity
  • Low Ionic Content, Low Outgassing
  • Used in Medical Applications

Questions Asked About PELESTAT/PELECTRON and Other FAQs

We are all familiar with electrostatic discharge.  It’s the “shock” you feel or spark you see when you shuffle across your carpeted living room on a winter morning and reach to touch the light switch.  While painful, these shocks are not the worst side of electrostatic discharge. When handling semiconductors (computer chips) electrostatic discharge can destroy thousands of dollars of value in a split second. In ATEX applications in a mine or oil refinery or flour mill, electrostatic discharge can ignite an nightmarish inferno resulting in unimaginable death and destruction. Fortunately, electrostatic discharge can be avoided with the use of static dissipative materials which gradually “bleed off” (dissipate) any build up of static charge.

Among the materials most vulnerable to electrostatic discharge are everyday plastics.  Virgin (uncompounded) plastics are inherently insulative.  When PELESTAT or PELECTRON are added to them, plastics become dissipative.  Since PELECTRON and PELESTAT are plastic additives, they must be added to plastic compounds with compounding equipment such as mixing extruders which employ powerful shear forces and high temperatures to disperse the additives evenly throughout the compound.

An antistatic additive is added to plastic compounds to eliminate problems caused by the buildup of static electric charge.

Static buildup in plastic parts can cause numerous problems.  In addition to the painful shock  we have all experienced, static charge attracts dust and dirt creating a dirty appearance. Also, static charge can cause thin film and sheet to stick together, reducing productivity.  Finally, for plastic components used in flammable environments such as flour mills, mines, refineries and oil drilling operation, static charge can ignite an explosion.

Traditionally, antistatic additives are migratory in nature, meaning that they function by constantly bleeding or blooming to the plastic surface.

Since they function on the surface, these migratory antistatic additives are easily rubbed off or washed off, reducing their effectiveness and contaminating adjacent items.  Also, they lose effectiveness over time, and since they must attract  atmospheric moisture to function they do not work well in dry environments.

Inherently dissipative polymers are also known as permanent antistatic additives.  Since they are polymers, they do not migrate, do not wear off, do not wash off, offer permanent performance and are not dependent on atmospheric humidity

Most plastics are naturally insulative, meaning they do not conduct electricity and will hold a static electric charge.  A static dissipative plastic is one which has been compounded with a suitable additive to allow a slow discharge of static electricity.  A slow discharge of static electricity is essential in flammable environments in order to avoid sparking which can ignite an explosion.

The recommended test is ASTM D257.  Results are expressed as “Ohms per square”.  Higher numbers indicate higher electrical resistance and slower dissipation.  Lower numbers mean lower electrical resistance and faster dissipation. 

That depends. Traditional migratory antistatic additives must absorb moisture from the atmosphere in order to function.  As a result they do not perform well in dry environments.

However, permanent antistatic additives do not rely on atmospheric moisture and this perform well in all environments, including the very dry.

The ATEX Directives (2014/34/EU & 1999/92/EC) are regulations of the European Union intended to protect employees from possible ignition of flammable or explosive atmospheres.

Examples of applicable industries would be oil/gas drilling operations, refineries, mines and powder processing operations such as sugar and flour mills. These directives require the dissipation of static electric charges.
