Antibacterial and antifungal agent for PVC soft door curtains, Grade 0 mold prevention
For the antibacterial and anti-mold requirements of PVC soft door curtains, it is recommended to use professional PVC-specific antibacterial and anti-mold agents. The specific selection should be based on cost, processing technology and anti-mold grade requirements. The following is a detailed analysis:
I. Core demands match the product
PVC soft door curtains, due to long-term exposure to damp environments such as kitchens, bathrooms, and warehouses, are prone to mold and bacteria growth, leading to discoloration, unpleasant odors, and even structural damage. Antibacterial and antifungal agents need to meet the following characteristics:
Broad-spectrum antibacterial property: Effective against common bacteria such as Escherichia coli and Staphylococcus aureus, as well as molds like Aspergillus Niger and Penicillium.
Durability: Stable at PVC processing temperatures (typically 160-200℃), and continuously inhibits bacteria throughout its service life.
Safety: Complies with environmental protection standards (such as REACH, ROHS), and is harmless to the human body.
Compatibility: It does not conflict with PVC resin, plasticizers and other additives, and does not affect the transparency and flexibility of the door curtain.
Iii. Key Indicators for Selection
Mold resistance grade: Prioritize products with mold resistance grade 0 (no mold growth within 28 days) or Grade 1 (slight growth).
Antibacterial rate: It needs to reach over 99% to ensure long-term usage effect.
Dosage: A low dosage (such as 0.4%-0.8%) can reduce the impact on the physical properties of PVC.
Qualification: Check whether the product complies with the EPA, FDA or domestic CMA certification standards to ensure compliance.
Iv. Application Suggestions
Processing technology: Pre-mix antibacterial and antifungal agents with PVC resin, plasticizers, stabilizers, etc. in a high-speed mixer, and then form through extrusion or calendering processes.
Compound use: It can be combined with inorganic antibacterial agents such as nano-silver and zinc oxide to enhance broad-spectrum performance and durability.
Regular inspection: It is recommended to conduct sampling tests on the antibacterial rate of each batch of door curtains to ensure stable quality.
