- Key Attributes
PUREstab 1010 has good compatibility, high resistance to extraction and low volatility. It is odorless and tasteless. The product can be used in combination with other additives such as co-stabilizers, e.g. thioethers (long term heat stabilizers), phosphites (secondary antioxidant), light stabilizers and other functional stabilizers. It is of particular interest to mention the enhanced effectiveness obtained by combining PUREstab 1010 with PUREfos 168.
Applications & Uses
- Compatible Polymers & Resins
- Applications
PUREstab 1010 is an efficient stabilizer for polyolefins, such as polyethylene, polypropylene, polybutene and olefin copolymers, such as EVA copolymers. Its use is also recommended for processing of polymers, such as polyacetals, polyamides and polyurethanes, polyesters, PVC, styrene homo- and copolymers, ABS, elastomers such as butyl rubber (IIR), SBS, SEBS, EPM and EPDM as well as other synthetic rubbers, adhesives, natural and synthetic tackifier resins.
- Guidelines for Use
Delivered at concentrations of 0.05% - 0.1%, PUREstab 1010 is providing long-term thermal stability to the polymer. Nevertheless, concentrations up to several percent may be suitable depending on the requirement of the end application and the substrate to be stabilized.
In polyolefins the recommended concentration levels of PUREstab 1010 range between 0.05% and 0.4% depending on the matrix, processing conditions and longterm thermal stability requirements. The optimum level has to be determined depending on the application requirement.
The concentration levels of PUREstab 1010 recommended:
- in hot melt adhesives, is ranging from 0.2% to 1.0%
- in synthetic tackifier resins, is ranging from 0.1% and 0.5%.
