SOG-03 Impact Modifier

What is an Impact Modifier?

An impact modifier is added to compounded materials to enhance the strength of the plastic.

Fine-Blend SOG-03 Impact Modifier

One of our impact modifiers, SOG-03, comes from our supplier and partner, Fine-Blend. SOG-03 is a POE-g-GMA (Glycidyl MethAcrylate grafted PolyOlefin Elastomer.) This product is exclusively distributed in North America by SACO AEI Polymers Distribution, a business unit of SACO AEI Polymers, part of the AESSE Investments group. 

The GMA (epoxy) functional groups react to the polyester carboxyl end groups. 

The polyolefin elastomer of SOG-03 has excellent flexibility and very low Glass Transition Temperature (Tg= -58 degrees Celsius) for optimal impact properties.

The SOG-03 provides toughening efficiency, thermal/color stability, and better melt flow than other common impact modifiers. 

Good Flowability= Better Processability 

Fine-Blend SOG-03 can also be used as a toughener in PC/PBT alloys. The graph below shows that with 3% or more of SOG-03, a 70/30 PC/PBT compound reached brittle-to-ductile transition.

The impact-fracture surface of the super-tough PC/PBT blend on the right shoes a typical ductile mechanism.

Recommended Dosage of SOG-03 Impact Modifier:

  • 18-20 wt % in toughened PBT and PET based compounds 
  • 6 wt % or more in Flame Retarded PBT or PC/PBT compounds
  • 2 wt % or more in Glass-Filled PBT compounds
