PUREstab 245 provides excellent processing and long-term thermal stability to plastics especially when used in combination with phosphites and / or thioether antioxidants. The effectiveness of PUREstab 245 with PUREfos 168 is noteworthy.
Applications & Uses
- Compatible Polymers & Resins
- Applications
PUREstab 245 is a highly effective antioxidant and process stabilizer in styrenic polymers (ABS, MBS, HIPS, and SB / SBR lattices), polyacetals, thermoplastic polyesters (especially PBT), polyamides, polyurethanes, PVC, other polymers, adhesives, and sealants. In addition to imparting thermostability to the finished polymer PUREstab 245 is effective as chain stopper during PVC polymerization.
PUREstab 245 is also suitable for use in combination with light stabilizers, including hindered amine light stabilizers (HALS), UV absorbers, and benzoates. Recommended concentrations in plastics, adhesives, and sealants range from 0.05 to 0.1% but up to 1.0 % can be used depending on the substrate and the requirements of the end application.
