Description:

 

FUNDILIZER 622 is the light stabilizer for all minimal migration and low volatility application, due to his oligomeric structure with high molecular weight. further more, FUNDILIZER 622 is effective as antioxidant and contributes significantly to the long-term heat stability of polyolefins and tackifier resins.

 


Function:

 

FUNDILIZER 622 is the light stabilizer for all minimal migration and low volatility application, due to his oligomeric structure with high molecular weight. further more, FUNDILIZER 622 is effective as antioxidant and contributes significantly to the long-term heat stability of polyolefins and tackifier resins.

 

 

Use:

 

polyolefins (PP,PE), olefin copolymers such as EVA ,polyacetals, polyamides, polyurethanes, flexible and rigid PVC, as well as PVC blends and in certain styrenic elastomer and adhesive specialty applications.

 

FUNDILIZER 622 areas of application include polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers.
In addition FUNDILIZER 622 is highly effective in polyacetals, polyamides and polyurethane applications.

Competitive Advantage:

 

The effectiveness of FUNDILIZER 622 surpasses significantly that of UV absorbers, particularly in pigmented systems. Combinations of FUNDILIZER 622 with UV absorbers. Typical examples are FUNDILIZER 783.

 

 

Guidelines for use

 

Thick sections* UV stabilization of HDPE, LLDPE,LDPE and PP 0.15-0.5%
Films UV stabilization of LDPE and LLDPE 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%
Guidelines for use
* The presence of a UV absorber (e.g. FUNDILIZER 326/327/328 and FUNDILIZER 531) is recommended in unpigmented or slightly pigmented articles or to improve the light fastness of certain organic pigments
