What is the OIT 45% specification for rubber products?
Jan 21, 2026| As a supplier of OIT 45% products, I often encounter inquiries from clients about what the OIT 45% specification for rubber products actually means. In this blog post, I will delve into the details of this specification, its significance in the rubber industry, and how our OIT 45% products can meet the specific needs of rubber manufacturers.
Understanding OIT and Its 45% Specification
OIT, or 2-Octyl-4-isothiazolin-3-one, is a powerful biocide that has gained wide acceptance in various industries, especially in the rubber sector. It is known for its excellent antibacterial, antifungal, and anti-algal properties. The "45%" in the OIT 45% specification refers to the concentration of OIT in the product. This means that in our OIT 45% formulation, 45% of the total composition is pure OIT, while the remaining 55% consists of solvents, stabilizers, and other additives that help maintain the product's stability and effectiveness.
The choice of a 45% concentration is not arbitrary. It represents a balance between efficacy and cost. A higher concentration of OIT would provide stronger biocidal activity, but it would also increase the cost of the product. On the other hand, a lower concentration might not be sufficient to provide adequate protection against microbial growth. The 45% concentration has been found to offer optimal performance in terms of preventing the growth of bacteria, fungi, and algae on rubber products while keeping the cost within a reasonable range.
Significance of OIT 45% in Rubber Products
Rubber products are prone to microbial attack due to their organic nature and the presence of moisture and nutrients. Microbial growth on rubber can lead to a variety of problems, including discoloration, odor, degradation of mechanical properties, and even health risks in some cases. This is where OIT 45% comes in.
By incorporating OIT 45% into rubber products during the manufacturing process, manufacturers can effectively prevent the growth of microorganisms. This not only extends the lifespan of the rubber products but also maintains their aesthetic and functional properties. For example, in rubber seals used in automotive applications, OIT 45% can prevent the growth of mold and bacteria, ensuring that the seals remain flexible and airtight over time. In rubber flooring, it can prevent the formation of unpleasant odors and stains caused by microbial activity.
Moreover, OIT 45% is also effective against a wide range of microorganisms, including gram-positive and gram-negative bacteria, fungi, and algae. This broad-spectrum activity makes it a versatile solution for different types of rubber products used in various environments.

Our team of experts can work closely with you to develop a formulation that is tailored to your requirements, taking into account factors such as the type of rubber, the intended application, and the environmental conditions.
Comparison with Other Biocides
There are several other biocides available in the market for rubber products, such as Bronopol For Mildew Protection, SPT40, and CMIT/MIT 14 Biocide. While these biocides also have their own advantages, OIT 45% offers some unique benefits.
Compared to Bronopol, OIT 45% has a longer-lasting biocidal effect. Bronopol is a fast-acting biocide, but it can degrade relatively quickly in the presence of heat, light, and moisture. OIT 45%, on the other hand, is more stable and can provide long-term protection against microbial growth.
SPT40 is another popular biocide, but it has a narrower spectrum of activity compared to OIT 45%. OIT 45% is effective against a wider range of microorganisms, including some that are resistant to SPT40.
CMIT/MIT 14 Biocide is known for its strong biocidal activity, but it can be more toxic and irritating compared to OIT 45%. OIT 45% is a more environmentally friendly and safer option, making it suitable for use in a variety of applications, including those where human contact is likely.
Applications of OIT 45% in Rubber Products
OIT 45% can be used in a wide range of rubber products, including:
- Automotive Rubber Parts: Such as seals, gaskets, and hoses. OIT 45% can prevent the growth of microorganisms on these parts, ensuring their proper functioning and longevity.
- Industrial Rubber Products: Like conveyor belts, rubber sheets, and diaphragms. It can protect these products from microbial degradation, reducing maintenance costs and downtime.
- Consumer Rubber Goods: Such as rubber toys, footwear, and household items. OIT 45% can provide a hygienic and odor-free environment for these products, enhancing their consumer appeal.
- Medical Rubber Products: Such as gloves, catheters, and tubing. It can prevent the growth of bacteria and fungi on these products, reducing the risk of infections.
