Chemical Structure
Typical Properties
Product Form: Solid
Melting Range: 90 – 98oC
Applications
BNX® 2042 is a highly effective, phenol-free hydroxylamine-based antioxidant designed for applications requiring excellent color stability and resistance to gas fading. It is particularly well-suited for polypropylene fiber, where it enhances melt processing stability and maintains low color during manufacturing. In automotive TPO and TPE applications, BNX® 2042 provides superior protection against gas fading and discoloration, ensuring long-term aesthetic and mechanical integrity. It is also ideal for use in polyolefins where low color and high thermal stability are critical. When combined with phosphite antioxidants such as Benefos® 1680 or Benefos® 1626, BNX® 2042 functions as part of a high-efficiency melt processing stabilizer system, delivering enhanced protection against thermal degradation and discoloration during polymer processing.
Advantages
- Provides excellent melt stability and color control in polyolefins and other plastics
- Synergistic performance with phosphites and/or hindered amine light stabilizers (HALS)
- Inherently resistant to discoloration from gas fading
- Good resistance to extraction
- Low-volatility
- FDA compliant
Guidelines for Use
Suggested use levels range from 0.02% to 0.2% in polyolefins. Combinations of BNX® 2042 with phosphites (BENEFOS® 1626, BENEFOS® 1680) and/or HALS (especially BLS® 119, BLS® 1944) often show synergistic performance. BNX® 2042 is also suitable for use in combination with other light stabilizers, including UV absorbers, and benzoates. The exact formulation to be used is dependent on the substrate, performance requirements, and other factors, and should be determined by the user based on testing to simulate actual conditions of use. Please contact your Mayzo representative for specific recommendations for your application.
