- Product Applications
PUREsorb 234 areas of application include molded articles, films, sheets and fibers. In addition PUREsorb 234 is highly effective in high temperature processed polymers such as poly-carbonate, polyesters, polyacetal, polyamides, polyphenylene sulfide, polyphenylene oxide, aromaticcopolymers, thermoplastic polyurethane and polyurethane fibers, where loss of UVA is not tolerated as well as for polyvinylchloride, styrene homo-and copolymers.
PUREsorb 234 may be use in range between 0.15 - 0.60%, depending on substrate and performance requirements of the final application. PUREsorb 234 can be used on its own or can be blend with other UVA and stabilizers where often a synergistic performance is observed.
