Certified Bacterial Resistance | Landy PVC Pool Liner Passes Bacterial Resistance Testing

Landy Group’s PVC Pool Liner has officially completed authoritative microbial resistance testing and secured a professional antibacterial test report.

Authoritative Standards, Rigorous Testing Conditions

The test was conducted by an authoritative third-party agency in accordance with the ISO 846:2019 standard (Evaluation of the action of microorganisms on plastics):

Test Strain: Pseudomonas aeruginosa (ATCC 13388)

Test Duration: Long-term test spanning 28 days

Rigorous Environment: Sealed incubation at a constant 29°C and 95% high humidity

High-temperature, high-humidity environments are prone to bacterial growth; this setup effectively tests the material's bacteriostatic capabilities by simulating real-world scenarios involving prolonged dampness and frequent contact.

Impressive Results: Long-lasting Inhibition of Bacterial Growth

After 28 days of continuous microbial incubation, visual inspection revealed no signs of bacterial growth on the PVC Pool Liner sample surface. Even in a warm, humid environment conducive to the rapid proliferation of Pseudomonas aeruginosa, the product maintained a clean surface. This demonstrates the material's excellent bacterial resistance and bacteriostatic properties, showing it does not easily serve as a breeding ground for bacteria.

Product Advantages: Suitable for Diverse Applications

Leveraging its superior bacterial resistance, this PVC Pool Liner offers the following key advantages:

▪ High bacteriostatic performance: Resists the growth of pathogenic bacteria like Pseudomonas aeruginosa in humid environments

▪ Material stability: Resistant to microbial degradation and deterioration during long-term use

▪ Reinforced substrate: Combines toughness with antibacterial performance

It is widely applicable in waterproofing scenarios—such as protective surfacing, commercial swimming pools, and pool renovations—adding a protective health barrier to daily use.

Professional Certification: Visible Quality

The testing agency holds the relevant qualifications, ensuring reliable data. The report (No. WJ2025002729) includes full documentation of the testing process, conditions, and photographic records of the samples, making the results fully verifiable.

Landy maintains strict control over raw materials and production processes. Beyond merely meeting performance standards, the company prioritizes health and safety attributes, using professional test data to guarantee the quality of every product. Landy consistently prioritizes quality, balancing product durability with health and safety to provide customers with clean, durable waterproofing and decorative solutions for swimming pools.
