Stabilizer and metal deactivator for plastic materials

Hostanox® OSP 1

Hostanox OSP 1 is a high efficient  antioxidant and metal deactivator which prevents the auto-catalytic decomposition of polyolefins. The usage of metal deactivators is mandatory as long as the polyolefin based finished article comes into contact with transition metals, such as Cu, Fe, Ni, Ti, etc.
  • Excellent thermal stability
  • Low volatility
  • Good extraction resistance in applications with contact to liquid media
  • Less impact on the color of the resin compared to other metal deactivators
  • High contribution to OIT
Classification according CLP regulation (Regulation (EC) No. 1272/2008, as amended)
    Skin sensitization, Cat. 1
For further information please refer to the Material Safety Data Sheet.
Physical Properties
Melting Range  106-124 °C
Solubility Soluble in acetone, isopropanol, toluene, ethyl acetate, chloroform, methanol
Insoluble in water
Hostanox OSP 1 is a metal deactivator with high migration- and extraction resistance. It is very suitable for plastics in particular for polyolefins which are in contact with metals e. g. cable filler black carbon and fittings. Furthermore, Hostanox OSP 1 leads to a remarkable improvement of the OIT value being required in polyethylene pipe applications. In addition, it is recommended for cross-linked polyethylene.
