Sanitized prepares for Cinte Techtextil China

In the build-up to the event, the company said that regulatory developments in recent years have limited the availability of biocides that can be used to protect polymers and textiles from bacterial and fungal growth.
For example, it pointed out that biocide OBPA was widely used to protect PVC and other plastics in the past, but that the European Union had blocked OBPA from sale in 2013. Alternatives such as DCOIT, BBIT, zinc pyrithione or IBPC have “their own limitations”, Sanitized said, in flexible polymer applications.
It said textiles for use in outdoor applications in particular have seen an increase in performance requirements. Antimicrobial effectiveness has to continue after exposure to water and ultraviolet light, for example, and should not contribute to yellowing.
Antimicrobial additives also need to be able to meet the requirements for heat stability during the application process, while also avoiding initial discoloration and demonstrating compatibility with other additives in the formulation. “Available alternatives often fall short in this regard,” the company said.
Its claim is that PL 14-32 offers “highly effective, long-lasting antimicrobial protection for flexible polymer applications”, taking all these criteria into account.
