- Key Attributes
PUREsorb 3346 provides a minimal color contribution to the substrates; it has low volatility and excellent compatibility with other HALS and UV absorbers. It has a good solubility/migration balance and is FDA sanctioned in polyolefins. PUREsorb 3346 light stabilizer in polypropylene and high density polyethylene at concentrations not exceeding 0.3 percent by weight of the polymer.
Applications & Uses
- Compatible Polymers & Resins
- Product Applications
PUREsorb 3346 areas of application include polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers. In addition, in certain instances PUREsorb 3346 is highly effective in polyacetals, polyamides, polyurethanes, flexible and rigid PVC, as well as PVC blends and in certain styrenic elastomer and adhesive specialty applications. Use in other olefin polymers at concentrations not exceeding 0.3 percent by weight of the polymer is limited to articles having a volume of at least 5 gallons.

Storage & Handling
- Product Handling
In accordance with good industrial practice, handle with care and avoid unnecessary
personal contact. Severe eye injury was produced during primary irritation studies. Inhalation exposure to the dust may produce eye, nose and throat irritation. Repeated or prolonged skin contact may produce eczematous dermatitis or other skin reactions such as cracking and scaling of skin.- Storage Conditions
This product may be stored up to two years in a sealed container. Containers should be kept tightly closed when not in use and stored in a cool, dry place.
