they are prone to bacterial and mold growth, resulting in odors, mold spots, and stickiness. Conventional antibacterial additives are not suitable for the PVC extrusion and calendering high-temperature process, and may cause production and finished product defects such as yellowing, precipitation, poor dispersion, and short antibacterial duration.

I. Pain Points in the Industry of Silicone Rubber Products Against Mold Growth Silicone rubber sealing rings, kitchenware, wearable accessories, and medical consumables are often exposed to humid, sealed, and highly oily environments, making them prone to adsorbing mold spores and breeding mold species such as Aspergillus niger and Mucor. As a result, they may develop mold spots, odors, and lose their luster.

I. Overview of the Requirements for Antibacterial Modification of Spunbond Nonwoven Fabrics PP spunbond non-woven fabric is widely used in fields such as medical protection, hygiene care, and household filtration. The common base material is prone to the growth of Escherichia coli, Staphylococcus aureus, and mold, presenting problems such as cross-infection, unpleasant odors, and moldy conditions.

The rubber and plastic products have been upgraded with antibacterial functions. The stability, safety and processing compatibility of the core raw materials directly determine the quality of the finished products. Many rubber and plastic processing factories and product enterprises, when producing antibacterial plastics, will look for reliable and well-coordinated plastic antibacterial masterbatch brands. Dalian Tianwei , which has been deeply engaged in the field of microbial control additives for many years

Fully polyester fabric is widely used in printed home textiles, sportswear, outdoor luggage, industrial filter cloth, etc. Polyester itself does not mold, but the residues of sizing, dyes, and oils left from printing and dyeing will cause mold growth in the fabric during high-temperature and high-humidity storage, ocean transportation, and rainy seasons, resulting in mold spots on the fabric surface, color bleeding on the printing, fabric odor, and decreased color fastness, leading to batch returns and losses.

Lactic acid gypsum relies on its modified adhesive properties and molding stability and is widely used in gypsum components, decorative gypsum, self-leveling gypsum, and craft gypsum and other building materials. However, the material has a weakly acidic pore structure, high organic matter of lactic acid, and strong hygroscopicity, which makes it prone to the growth of mold such as Aspergillus niger, Penicillium, and yeast.

The plastic hollow fiber membrane, with its advantages such as high flux, good strength, resistance to acid and alkali, and ease of processing, is widely used in fields such as water purification filtration, wastewater treatment, reclaimed water reuse, and biomedical filtration. However, the porous structure of the membrane body easily adsorbs bacteria, molds

Water-based anti-corrosion coatings use water as the solvent, and have a high organic content of emulsions and additives. After storage in the tank and formation of the coating film, they are prone to bacterial, yeast, mold, and sulfate-reducing bacteria growth. They are a high-risk category in the coatings industry, presenting four prominent production and usage pain points:

The spinning oil agent preservative is a functional additive specifically designed for the textile and chemical fiber industry. It is mainly developed for spinning oil agent systems of polyester, nylon, polypropylene, etc.
