Hostanox® OSP 1

Stabilizer and metal deactivator for plastic materials

Edition Number :
5
Edition Date :
January 01, 2014
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.

Benefits

  • 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

Applications

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.
