HOSTANOX P EPQ PILLS

PROCESSING STABILIZER FOR COATINGS AND PLASTIC MATERIALS
  • Product Type: Diphosphonite
  • Master Product Number: MITM02916
  • Product SKUs: ITM25149, ITM17270

Product Details

Hostanox P-EPQ pills is a highly efficient phosphorus based secondary antioxidant, which reduces the thermo-oxidative degradation of polymers and the development of undesired colour (yellowing) during processing. The main advantages of Hostanox P-EPQ pills are its high thermal stability and high solubility in polymeric materials as well as its broad compatibility in coating polymers.

Benefits

Plastics
  • Low dosage
  • High performance in color and melt flow retention during conversion process
  • White application window allowing high processing temperatures
  • Low softening temperature providing early stage protection in extrusion processes
  • Significant contribution to dyne level retention
  • High solubility in polymer virtually no haze or blooming
  • High contribution to thermal stability of filled Polyolefin and engineering plastic compounds
  • Higher contribution to Polypropylene clarity compared to other processing stablizers
  • Low plate out, low die buildup
  • Preventing formation of char and specks
Coatings
  • High contribution to termal yellowing reduction during processing and long term heat stability
  • Inhibit discoloration due to Stoving/NOx
  • Reduce Gas Fading

Typical Applications

Coatings

Hostanox P-EPQ pills is recommended especially for the applications where polymers and/or binders are cured at elevated temperature and need thermo-stabilization, e.g. powder coatings, coil coatings and specific solventborne coatings (automotive for ex.).

Plastics

Hostanox P-EPQ pills is suitable for most kinds of thermoplastic polymers. It is recommended especially for the stabilization of polyolefins (LLDPE, HDPE, PP), ABS, PS, polybutylene, PBT, PC, PA, thermoplastic polyester, nitrile barrier resins, etc.
