Plastics

Antimicrobial additives are facing greater scrutiny in the plastics industry because of COVID-19 and wider awareness around food safety and good hygiene. Many antimicrobial additives have been phased out or limited in plastics applications where there is food or human contact. Janssen PMP recognizes the need for safe, affordable, and hygienic antimicrobials in plastic. Zinc PYRION™ is a cost-effective antimicrobial that improves health and hygiene for plastic products. Zinc PYRION™ antimicrobials stop fungi from discoloring, staining, and destroying plastic, and prevents the growth of bacteria and algae on plastic surfaces. Zinc PYRION™ is also compatible with most polymers and co-formulants, and is stable at high temperatures during polymer processing. Add value to your plastic products by incorporating a durable and effective preservative like Zinc PYRION™.

Textiles 

---

Microorganisms cause unwanted odors and staining on textiles and footwear. Zinc PYRION™ provides long-lasting protection from bacteria and fungi so textile products stay fresh for longer. Zinc PYRION™ also has limited solubility in water, meaning the antimicrobial stays in the textile and footwear for longer, improving the product’s durability and performance. 

 

Examples of approved textile applications for Zinc PYRION™ include: 

• Carpet fibers 

• Wall coverings 

• Laundered fabrics 

• Components of footwear 

• Coated fabrics for furniture cushions 

• Fiber mops
