Medical Resin Hospital Doors Achieve 99.99% Antibacterial Rate

ZONLE Hospital Doors – Antibacterial Performance Tested Against Staphylococcus aureus and Escherichia coli

Medical environments require door surfaces that are easy to clean and help maintain hygienic conditions. To evaluate the antibacterial performance of our Medical Resin Hospital Door, an antibacterial activity test was conducted according to GB/T 31402-2015.

The test evaluated the antibacterial activity of the door material against Staphylococcus aureus ATCC 6538 and Escherichia coli ATCC 8739. The results showed an antibacterial rate of 99.99% for both tested bacterial strains.

Sample Information

Antibacterial Test Results

The test compared bacterial counts on the control samples and the Medical Resin Door samples after 24 hours of incubation.

The test results demonstrate a 99.99% antibacterial rate against both Staphylococcus aureus and Escherichia coli under the specified laboratory test conditions.

Test Results for Staphylococcus aureus

For Staphylococcus aureus ATCC 6538:

• Control sample after 0 hours: 2.1 × 10⁴ Cells/cm²
• Control sample after 24 hours: 2.3 × 10⁵ Cells/cm²
• Medical Resin Door sample after 24 hours: 1 Cell/cm²
• Antibacterial activity value (R): 5.36
• Antibacterial rate: 99.99%

Test Results for Escherichia coli

For Escherichia coli ATCC 8739:

• Control sample after 0 hours: 1.6 × 10⁴ Cells/cm²
• Control sample after 24 hours: 2.1 × 10⁵ Cells/cm²
• Medical Resin Door sample after 24 hours: 1 Cell/cm²
• Antibacterial activity value (R): 5.32
• Antibacterial rate: 99.99%

What Does the 99.99% Antibacterial Rate Mean?

The laboratory results indicate that the tested Medical Resin Door surface significantly inhibited the growth of the two tested bacterial strains compared with the control sample.

The tested microorganisms were:

• Staphylococcus aureus – ATCC 6538
• Escherichia coli – ATCC 8739

With an antibacterial rate of 99.99% against both strains, the Medical Resin Door is designed to support hygienic requirements in environments where regular cleaning and sanitation are important.

Note: The 99.99% result applies to the tested sample, bacterial strains, test method and specified laboratory conditions. It should not be interpreted as a claim that the door can completely prevent infection or eliminate all microorganisms.

Why Antibacterial Performance Matters for Hospital Doors

Doors in hospitals and healthcare facilities are frequently touched by medical staff, patients and visitors. They may also be exposed to regular cleaning and disinfection.

For this reason, Hospital Doors require more than a conventional architectural door. Surface hygiene, cleanability, durability and resistance to demanding environments are important considerations.

The tested Medical Resin Door can be considered for applications such as:

• Hospitals and healthcare facilities
• Patient rooms and wards
• Clinics
• Laboratories
• Clean areas
• Treatment rooms
• Pharmaceutical facilities
• Other hygiene-sensitive commercial environments
