Introduction :
YS 622 is the low volatility and minimal migration , because of its oligomeric structure with high molecular weight. Furthermore YS 622 is effective as antioxidant and contributes significantly to the long term heat stability of polyolefins and tackifier resins.
Application :
YS 622 areas of application include polyolefins(PP , PE) , olefin copolymers such as EVA as well as blends of polypropylene with elastomers. In addition YS 622 is highly effective in polyacetals , polyamides and polyurethane applications.
The effectiveness of YS 622 surpasses significantly that of UV absorbers , particularly in pigmented systems.
Guidelines for use :
Thick sections UV stabilization of HDPE , LLDPE , LDPE and PP 0.15~0.5%
Films UV stabilization of LLDPE and LDPE 0.1~1.2%
Tapes UV stabilization of HDPE and PP 0.2~0.8%
Fibers UV stabilization of PP fibers 0.1~1.0%
Handling and Safety :
In accordance with good industrial practice , handle care and prevent contamination of the environment. Avoid dust formation and ignition sources .For more ***ailed information please refer to the material safety data sheet.
