AO168 31570 – 04 – 4
AO B 225 – a processing and long - term thermal stabilizer system –
synergistic blend of AO 168 and AO 1010 .
- Name: AO B225
- CAS No.: AO1010 6683 – 19 – 8 , AO168 31570 – 04 - 4
AO B 225 is a convenient blend addressing a range of stabilization
needs . In the recommended applications AO B 225 provides
significant benefits , such as
• long - term thermal stability
• low color formation
• maintenance of original melt flow .
AO168 – an organophosphite of low volatility and particularly
resistance to hydrolysis – protects during processing organic
polymers which are prone to oxidation. AO 1010 – a hindered
phenolic antioxidant – contributes synergistically to the
stabilization of the polymer during processing and provides long -
term thermal stability by preventing thermo - oxidative degradation
during service life .
Guidelines for Use:
In polyolefins, the concentration levels for AO B 225 range
typically between 0.1 % and 0.25 %, depending on substrate and
processing conditions. The optimum level is application specific.
Extensive performance data of AO B 225 in various organic polymers
and applications are available upon request.
AO B 225 is used in polyolefins and olefin - copolymers such as
polyethylene , polypropylene , polybutene and ethylene -
vinylacetate copolymers . The blend can also be used in other
polymers such as engineering plastics , styrene homo - and
copolymers , polyurethanes , elastomers , adhesives , and other
organic substrates .
