For manufacturers of flexible PVC and artificial leather, maintaining durability, hygiene, and antimicrobial protection is essential in today’s market. HARKE Addi-Tec is pleased to present two key solutions: Sanitized® PL 14-32 and Sanitized® PL 19-30. 

These advanced additives from Sanitized® offer long-lasting material protection and meet stringent safety standards. Let’s take a look at the value they bring.

Long-Lasting Antimicrobial Protection with Sanitized® PL 14-32

Sanitized® PL 14-32 is designed to protect flexible PVC and artificial leather from microbial damage. This additive prevents common issues like pink staining and material degradation caused by bacteria, fungi and algae. Its benefits include:

• Broad Antimicrobial Efficacy: Sanitized® PL 14-32 offers extensive protection against bacterial and fungal growth. It enhances the durability and cleanliness of PVC and artificial leather surfaces, particularly in environments where hygiene is a priority.
• Material Stability: Unlike some other antimicrobial treatments, Sanitized® PL 14-32 does not alter the initial colour or affect thermal stability. It seamlessly integrates with existing PVC formulations and does not degrade under UV exposure, ensuring long-term performance.
• Ease of Use: With a ready-to-use, easy-to-dose and pumpable plastisol formulation, Sanitized® PL 14-32 can be directly incorporated into production processes.
• Safety: Sanitized® PL 14-32 is non-volatile and meets OEKO-TEX® Standard 100 for safe use in consumer products across various applications.

Addressing New Safety Standards with Sanitized® PL 19-30

Sanitized® PL 19-30 has gained attention as a powerful alternative to Zinc Pyrithione-based antimicrobial additives, which have recently been reclassified in the EU as toxic for reproduction (Category 1B, H360D) effective March 1, 2022. 

Sanitized® PL 19-30 provides manufacturers with a safe, effective substitute in light of this new restriction. 

Its key features include:

• Non-Sensitising Formula: Unlike many Zinc Pyrithione alternatives that carry skin-sensitising classifications, Sanitized® PL 19-30 is not classified as a sensitizer (H317). This makes it suitable for applications in materials that may come into direct contact with skin without causing irritation.
• High Antimicrobial Efficacy: This additive achieves a 99.99% reduction in bacterial growth on treated surfaces, making it ideal for artificial leather, PVC, coatings, and foams. Sanitized® PL 19-30 protects against bacterial, fungal and algae growth, extending the life and hygiene of treated products​.
• Sustainable and Safe Compliance: Sanitized® PL 19-30 is free from volatile organic compounds and heavy metals, and it meets OEKO-TEX® Standard 100 for safe use in consumer products across various applications. It also has 80% water-based content, which means lower environmental impact during application.

Real-World Applications in PVC and Artificial Leather

Sanitized® PL 14-32 and PL 19-30 enhance various products in the PVC and artificial leather sectors. Here are some typical applications:

• Artificial Leather: From upholstery to clothing, artificial leather benefits from Sanitized® PL 14-32’s resistance to microbial growth and staining, while Sanitized® PL 19-30 offers a non-sensitising, durable alternative for high-touch surfaces.
• Flexible PVC: Often used in environments prone to contamination, such as flooring and wall coverings, PVC treated with these additives remains cleaner and more durable, with minimal maintenance.
• Technical Textiles and Coatings: For items such as mattress covers, gloves, and protective gear, Sanitized® PL 19-30 provides long-lasting hygiene without compromising skin compatibility, making it ideal for industries that prioritise both safety and comfort​.

Next Steps

Sanitized® PL 14-32 and PL 19-30 offer advanced, safe, and effective antimicrobial protection for PVC and artificial leather applications. With the shift away from Zinc Pyrithione-based additives, Sanitized® PL 19-30 stands out as a reliable and non-sensitising alternative that meets today’s regulatory and safety standards.
