What's great about Sanyo Chemical's Permanent Antistatic Agent "PELESTAT"
1
Full Lineup for Various Resins and Molding Methods
When added to various resins such as ABS, PP, and PE, it quickly exhibits antistatic performance and permanently prevents problems caused by static electricity.
2
Low Pollution
Since "PELESTAT" is an ion-conductive polymer, there is no contamination of the resin surface due to bleed-out of antistatic agents.
3
Retention of Mechanical Properties
Minimizes the effect on hardness and heat resistance of plastics when added. While imparting an antistatic effect, there in almost no change in mechanical properties.
"PELESTAT" is Used to Solve Various Static Electricity Problems
It can be used to solve various static electricity problems, from preventing dust and powder from adhering to resin surfaces to explosion-proof applications.
Prevents Adhesion of Dust and Powder (Surface Resistivity: 1012 (Ω/sq.))
<Mainly Applied to Home Appliance Parts and Automobile Interior Parts>
Vacuum Cleaner Dust Box
Base Resin: Transparent ABS
(Injection Molding)
When added to a transparent dust box, it prevents dust adhesion caused by static electricity buildup on the resin surface, while maintaining transparency and visibility.
Refrigerator Parts
Base Resin: PP
(Injection Molding)
Prevents dirt from accumulating on the floor near the refrigerator scaffolds.
Air Conditioners, Air Cleaner Front Cover
Base Resin: HIPS
(Injection Molding)
Prevents stains caused by dust adhesion.
Medical Equipment (Inhalers)
Prevents powder from adhering to the inner wall due to static electricity, contributing to an accurate drug dosage.
Prevention of Sudden Discharge (Surface Resistivity: 1010 to 1011 (Ω/sq.)) <Applied Mainly for Explosion-proof Applications >
Explosion-proof helmet
Base resin: PP (injection molding)
They are also used in explosion-proof applications for plastic products because they suppress the generation of sparks caused by static electricity.
Flexible Container Pack for Powder (inner bag)
Base Resin: PE
(Inflation Molding)
Antistatic inner bags reduce the risk of dust explosions.

Permanent Antistatic Agent "PELESTAT"/"PELECTRON" vs. Low Molecular Weight Antistatic Agents
| Permanent antistatic agent PELESTAT PELECTRON |
Low-molecular-weight antistatic additives | |
|---|---|---|
| Surface resistivity (Ω/sq.) |
108～1012 |
109～1012 |
| Required additive amount (wt%) | 5～25 | 0.2～2 |
| Sustainability of antistatic effect | Good (Sustained) |
Poor (Not sustainable) |
| Humidity dependence of antistatic effect | Good (No humidity dependence) |
Poor (Worse under low humidity) |
| Antistatic properties immediately after resin molding | Good (Effective immediately after molding) |
Poor (No effect immediately after molding) |
Example of Evaluation of Maintaining Antistatic Properties
When LDPE containing a low molecular weight migratory type antistatic agent is washed, the antistatic effect wears off. In the case of a permanent antistatic agent, the surface resistivity does not change even after repeated washings.
Measurement method
Test pieces of LDPE resin were soaked in water, rinsed with a cotton cloth on the surface of the test piece, and then dried under reduced pressure (130 Pa, 70ºC, 2 hours). The test piece was then humidified for 24 hours at 23ºC, 50% R.H., and the surface resistivity was measured using an ultra-insulation meter.
LDPE resin: extrusion grade used [MFR = 2 g/10min (190ºC, 21.18 N)
Example of Evaluation of Humidity Dependence of Antistatic Effect
The surface resistivity of LDPE resin with a low molecular weight antistatic agent increases at low humidity, whereas the surface resistivity of LDPE resin with permanent antistatic agent does not change with humidity.
Measurement method
Test pieces of LDPE resin were placed in a room with a specific humidity at 23ºC for 24 hours, and then surface resistivity was measured using an ultra-insulation meter.
LDPE resin: extrusion grade used [MFR = 2 g/10min ( 190ºC , 21.18 N)
