Rubber Gloves

Chlorine Gas Application: Rubber Glove Manufacturing


Rubber gloves are essential protective equipment widely used in various industries, including healthcare, food handling, chemical processing, and more. The quality and performance of rubber gloves directly impact user safety and comfort. To meet the stringent requirements of different applications and ensure optimal glove characteristics, manufacturers in the rubber glove industry are continually seeking innovative approaches to enhance their glove production processes.

One such method that has emerged as a key enabler in rubber glove manufacturing is the targeted application of chlorine gas. Chlorine gas treatment has proven to be highly effective in modifying rubber glove properties, including strength, flexibility, and barrier performance. These enhancements lead to the production of rubber gloves with superior protection, durability, and overall quality.

This paper explores the application of chlorine gas in rubber glove manufacturing and its impact on glove quality and performance. It also highlights the crucial role played by Hydro Instruments, a leading provider of gas feed equipment, including equipment for chlorine gas, in ensuring the accurate and safe application of chlorine gas in rubber glove production. By understanding the benefits of chlorine gas treatment and leveraging Hydro Instruments’ expertise, rubber glove manufacturers can create gloves that meet the diverse safety needs of various industries.

Brief History of Rubber Gloves

The history of rubber gloves can be traced back to the late 19th century when their usage was predominantly focused on healthcare settings (Khazan, 2014). The primary driving force behind the invention of rubber gloves was the need for barrier protection against infections and contaminants. During this period, gloves were being crafted from various materials, but it was the discovery of the vulcanization process by Charles Goodyear in the mid-1800s that significantly revolutionized glove production (Bellis, 2018). Vulcanization, which involves the addition of sulfur and heat to raw rubber, greatly improved the elasticity, durability, and overall performance of rubber materials, making them ideal for glove manufacturing.

Initially, rubber gloves found their niche in healthcare, offering a solution to prevent cross- contamination between medical practitioners and patients (Moore, 2019). The development of the latex rubber glove marked a significant advancement, as latex offered a comfortable fit, flexibility, and effective barrier properties (Yip & Cacioli, 2002). Over time, as the demand for rubber gloves expanded across various industries like food processing, chemical handling, and more, manufacturers faced ongoing challenges related to enhancing glove strength, flexibility, and barrier effectiveness.

Advancements in material science and manufacturing techniques continued to reshape the rubber glove industry. Innovations such as powder-free gloves, textured surfaces for improved grip, and better sizing options emerged to address user needs. However, the evolution of rubber glove production was further accelerated through the application of technologies like chlorine gas treatment, which allowed for targeted modifications to the properties of rubber materials.

Role of Chlorine Gas in Rubber Glove Manufacturing

The utilization of chlorine gas has introduced a new dimension to rubber glove manufacturing by offering a strategic way to enhance the properties of latex rubber. Chlorine gas treatment is known for its ability to induce controlled chemical changes in the polymer structure of latex, resulting in noteworthy improvements in glove attributes, including strength, elasticity, and barrier characteristics (Wang & Morris, 2009).

The incorporation of powdered gloves into the manufacturing process involves dipping the gloves in a slurry, often referred to as wet powder (Lovato et al., 2023). This slurry contains constituents like talc, silica, or crosslinked starch. A significant step in the chlorination process entails immersing the gloves into a solution infused with chlorine. Through a chemical reaction with chlorine, a thin layer of chlorinated rubber forms on the glove surface. The chlorine solution is generated either by infusing chlorine gas into water.

Chlorination stands as the predominant method for producing powder-free natural rubber (NR) gloves. The polymer chains’ double bonds in NR exhibit a high propensity to interact with chlorine. The outcome of this interaction is the stiffening and detackifying of the glove’s rubber surface, which contributes to improved usability and comfort.

Incorporating these steps, chlorination creates a pivotal transformation in the latex material, thereby bolstering the mechanical and protective characteristics of the resulting gloves.

Furthermore, chlorine gas treatment has been found to improve the barrier properties of rubber gloves. The modified polymer structure forms a more effective barrier against liquids, chemicals, and microorganisms, enhancing the overall protective performance of the gloves. This is particularly important in industries where exposure to hazardous substances is a concern.
