UV light stabilizer

タイトルまたは説明

Hindered Amine Light Stabilizer（HALS）
 
It can protect from UV damage to the plastic, although itself hardly absorbs ultraviolet light, but can effectively capture the free radical which is generated by ultraviolet energy, so as to achieve the purpose of the light stabilizer.
 
HALS has different mechanisms with benzotriazole-based ultraviolet absorber, both of which can be obtained with a synergistic effect, and will exhibit good lightfastness
 
Hindered Amine Light Stabilizer（HALS）UV****3
 
Usage：The new type HALS can provide superior protection to a plastic surface properties; high solubility / compatibility with the polyolefin and of the styrene and the like; with other stabilizers, in particular, high molecular weight hindered amine light stabilizer has the most good synergy.
 
V**3
New generation stabilization system, focusing on the automotive sector PP, TPO and other polyolefin materials.
 
Features：Hindered amine complex systems; has no reaction with acidic substances; lower additives and compatibility, no fumigation and precipitation phenomena; excellent weather resistance; reduce dirt accumulation of residual mold after prolonged use; excellent finish adhesion.
  
HALS UV****6
 
C.N．：CAS No.*********7
appearance：pastille（colorless particle）
relative molecular weight：≥***0
melting point：******0℃
features：
Polymeric high molecular weight hindered amine light stabilizers, hindered amine-containing groups, as well as a triazine group, the excellent light stability, weather resistance, particularly high requirements for polyolefins have a good effect, extraction resistance and small thermal weight loss.
Application：mainly for polypropylene fibers and molded products, polyethylene-based products,ect.
 
High molecular weight HASL UV****9
used for PP PE as Long-acting light stabilizer which required excellent weather resistance
features：Color dirty low, low volatility, extraction resistance, anti-fumigation faded, acid resistance; effectively maintain master batch color retention rate; superior long-term anti-aging properties, to extend the service life and the durability of exterior color of the plastics.
Application：auto plastic、color master batch、Outdoor PP PE products such as tarpaulin, artificial grass, outdoor plastic toys, containers, rotomolding products,ect.
If you have higher request, we recommend to use THT series of CYTEC.
 
UV****8
 
PH=6.5, It does not react with the acid in acidic flame retardant system.
However **0,**4 belongs to hindered amine products so in acidic system it will decrease the activity of the acid from the neutralization reaction (generally Ciba recipe using **0 + **7), so ***8 has better performance.
 
New generation efficient light stabilizer
 
CYASORB THT™ light stabilizer *******1
 
Extend the life of polyethylene products, far more than the standard of traditional hindered amine products.
To achieve the same levels of ultraviolet resistance, significantly reduce the dosage of light stabilizer.
Excellent light stability, prolong the life of outdoor products to the level from UV*0 to UV*0 +
 
CYASORB THT ***1 ——suitable for all kinds of olefins and nylon
