Hindered Phenolic
Antioxidant |
1. It is a hindered phenolic antioxidant with low volatility and excellent resistance to gas fading. |
|
2. Hindered phenol antioxidant agent is gradually taking the place of arylarmines to be the mainstream antioxidant anent because of better capability with polymers,low toxicity and low pollution. |
3. Effectively protect polymers that are exposed to high temperatures and/or severe conditions during
processing and/or in use.Suitable for a variety of polymers,such as LDPE,ABS and PET,and it is particularly recommended for PP,HDPE,LLDPE,HIPS,PBT,POM,PA,PU and latex. |
|
4. Synergy with phosphite antioxidant and macromolecule sulfur antioxidants will bring better anti-heat-aging performance. |
应用
Application |
The experiment of effects of hindered phenol additives NOX-80 on the vulcanization properties shows that:
·After the addition off hindered phenol,the t10 and t90 of the blend was increased,ML changed a little,MH
decreased,indicating that the modulus of blends decreased;
·The hardness and elasticity decreased,100% tensile stress and tensile elongation increased slightly and then
dereased,tensile strength and tear strength decreased;
·After 100℃ hot air aging 24h,the retention rate of tensile strength and elongation at break rate
improved,the property of hot air aging improved;
·In the zone of glass transition,tan5 increased;in the temperature range of 0℃ -80℃ ,damping
performance improved.
