Chlorobutyl rubber is a copolymer made mainly of isobutylene and isothiocyanate. It contains dichloromethyl groups that replace some isobutylene molecules in the polymer structure. This will give Butyl rubber better chemical resistance and better adherent ability.
The structure of chlorobutyl rubber is a saturated polymer, which means it has good impermeability to air and gases. It also has a high level of elasticity and flexibility, which enables it to be used in a wide variety of industrial applications.
Thermal curing system
Precipitated sulfur is typically used as a curing agent in the chlorobutyl rubber thermal curing system, where the rubber is heated in the presence of sulfur and accelerators. With this system, useful chlorobutyl rubber products achieve enhanced elasticity, strength, and heat tolerance once the curing process is complete. These products include tires, seals, and hoses, where improved elasticity and resilience are ideal. The thermal curing system can be used in large-scale production, which makes it a preferable method in many commercial settings.
Cold curing system
Chlorobutyl rubber is cured using a combination of zinc oxide, fatty acids, and chemical accelerators in a cold curing system. This system does not need heat, which makes it easier and more accessible in small and medium-sized enterprises (SMEs). While the cold curing system does not give as much elasticity and resistance to heat as the thermal system, it is still helpful for applications that do not require high levels of resilience. These usually include gaskets and seals.
Halo polymer butyl rubber
Halo polymer butyl rubber is butyl rubber that contains halogen elements (usually chlorine or bromine) incorporated into its structure. This is mainly done to increase resistance to chemical elements and better the polymer's ability to adhere to surfaces such as fabrics and cords. Halo polymer butyl rubber is commonly used in tires, inner tubes, and other goods that need protection against gases and moisture due to its gas impermeability qualities.
Liquid butyl rubber
Liquid butyl rubber is a polymer that is dissolved in a solvent to give it a liquid form. This allows easy application in thin layers or as an adhesive. It is mainly used for coating, sealing, and bonding purposes, giving excellent gas isolation and weathering resistance properties. After the solvent evaporates, the rubber remains giving a flexible elastic result. Liquid butyl rubber is commonly used in construction, automotive, and marine industries.
Tire manufacturing
Chlorobutyl rubber is widely used in tire manufacture as the inner liner material. This is due to its ability to contain air and prevent it from escaping through the tire structure.

Chlorobutyl rubber is found in some medical devices due to its sterilization resistance and durability.
Consumer goods
Chlorobutyl rubber is found in goods like adhesive tapes and sealing compounds in consumer goods. Its good resistance to moisture and gases makes it useful in sealing applications, like water-resistant and air-tight products. Furthermore, chlorobutyl rubber's ability to resist aging gives it long-lasting durability in goods commonly used in consumers' daily lives.
Building and construction industries
In construction industries, Chlorobutyl rubber is used by builders to provide weatherproofing and sealing goods. Its ability to resist water, gases, and various weather elements makes it ideal for use in roof seals, windows, and doors. In addition, chlorobutyl rubber's good resistance to ozone helps protect it from degradation caused by prolonged outdoor exposure.
Marine applications
Due to its resistance to water and ozone, chlorobutyl rubber is used in marine applications for boat seals and gaskets. It also resists degradation caused by prolonged contact with harsh marine elements, thus obtaining chlorobutyl rubber's durability and dependability when used in marine environments.
Chlorobutyl rubber has different specifications and features that enable it to perform well for its intended purposes. Here are some of the general features and specifications of chlorobutyl rubber:
Resistance to chemicals
The addition of chlorine provides improved resistance to solvents such as oils, acids, and bases. This makes it suitable for use in industrial and automotive applications where exposure to chemicals is frequent and expected.
Adhesion properties
Chlorobutyl rubber better adherent ability to polar substrates like metal and fabric compared to regular butyl rubber. Because of this, it is good for manufacturing tires and other goods where bonding to different surfaces is essential.
Elasticity and flexibility
Chlorobutyl rubber retains good elasticity and flexibility at a wide range of temperatures. This enables it to perform in adverse weather conditions, including extreme heat or cold.
Sheet and mold castability
Chlorobutyl rubber can be processed into sheets and molds like most common rubbers. This makes it easy to use in manufacturing processes where it can be shaped into parts or layered into products requiring this rubber's isolative properties.
Durability and aging
The saturation of the polymer backbone with halogen atoms helps improve its resistance to ultraviolet (UV) light and ozone. These two are common factors that contribute to rubber degradation or aging. This means that chlorobutyl rubber products will have a longer lifespan and retain useful qualities during extended outdoor exposure.
Thermal and cold curing
Chlorobutyl rubber can be thermally cured or cold cured. The thermal-cured products have better elasticity and resistance to heat. Cold-cured products are easier to manufacture and wear less energy for businesses to produce.
Impregnation and filled systems
Date systems like mineral fillers and other solids can be added to chlorobutyl rubber to enhance its properties or modify its uses. For example, adding fillers can increase tensile strength, improve thermal stability, or reduce manufacturing costs.
Because of its wide applications, the quality and safety of chlorobutyl rubber will be considered by manufacturers, including its curing, purity, processing, and end-product testing.
Material purity
The presence of contaminants or impurities in chlorobutyl rubber can affect product safety and performance. Thus, manufacturers should ensure that the raw materials used to produce the rubber are pure and free from contaminants that may adversely affect the rubber's chemical or physical properties.
Quality raw material
Using high-grade isobutylene and butylene that are free from impurities and have consistent supply will contribute to the high quality of chlorobutyl rubber. On the other hand, low-grade raw materials could cause product defects or variations that reduce its effective and efficient uses while harmful to health.
Control of processing conditions
Monitoring temperature, pressure, and time during chlorobutyl rubber production is vital in ensuring its quality. Any variation could affect its physical and chemical properties, making them unsafe or unsuitable for certain uses. Thus, proper equipment calibration, manufacturing environment control, and workers' instructions are vital parts of the production processes that must be strictly adhered to.
Proper storage and handling
Exposure to environmental elements such as sunlight, ozone, and heat can degrade chlorobutyl rubber. So, both the raw material and the final product must be properly stored in cool, dark, and ozone-free environments. They should also be kept away from sharp items, oils, and chemicals that may cause degradation or contamination. Again, personnel who handle these materials should be sensitized not just to protect themselves but also to handle the materials appropriately to avoid contamination and degradation.
Consistency in manufacturing and formulation
Considering the same formulations and manufacturing processes brought about the same product results, manufacturers should strive to be consistent in every step. This eliminates variations that could result in unsafe products or those of low quality made with one of the highest-selling rubber composites.
End-product testing
Chlorobutyl rubber manufacturers should carry out tests to check the chemical and physical properties of the rubber and its safety. Toxicity tests for harmful chemicals like chlorine should be carried out to ensure they do not reside in the rubber. Physical property tests like tensile strength, elasticity, and resistance to different chemicals, weather, and gases should be carried out to ensure the rubber performs its duties as expected and in a safe manner.
A1: Chlorobutyl rubber is an artificial rubber comprising butyl rubber and chloromethyl groups. This makes the rubber more resistant to chemicals and offers better adhesion to surfaces like fabrics and metals. Chlorobutyl rubber is widely applied in tires, seals, and other industrial products that require good gas isolation and durability.
A2: Chlorobutyl rubber is widely applied in tires, especially the internal liner, where it isolates gases. It is used in the automotive industry to manufacture seals and gaskets, especially in the engine, where chemical and heat resistance is necessary. It is used in pharmaceutical closures and seals, such as stoppers for vials, because of its inertness to various chemicals. It is used in some consumer goods, industrial applications, and marine products that offer effective moisture and gas isolation and outstanding resistance to environmental and weather conditions.
A3: Chlorobutyl rubber's advantages include excellent resistance to ozone, UV rays, and chemicals like oils, acids, and bases, which makes it last longer in outdoor settings. Its rubbery elastomer provides effective airtight isolation, better solid than liquids, and can bond with surfaces like metals, which makes it useful in tires and other goods. Its versatility enables it to be used in tires, pharmaceutical seals, and other goods. Its cold curing makes its production easier with less energy consumption.
However, chlorobutyl rubber has some limitations. Unlike natural rubber, its elasticity is lower, and so is its flexibility, making it less resilient. It is also more expensive than its butyl counterparts due to its complex manufacturing process. Being synthetic, it is not biodegradable, contributing to environmental pollution.
A4: Some factors that should be considered for quality contain the chemical composition of the rubber. Pure butyl rubber with not less than 85% isoprene will make the rubber effective. The rubber product should undergo effective quality tests to ensure it meets standards like ASTM. Care should also be taken to avoid contamination, which can be caused by handling or storing the rubber improperly. Products should go safety tests for harmful components like chlorine and heavy metals and disclose the results.
A5: Yes, since it is made of polymers, chlorobutyl rubber can be ground down and reused in making new rubber products. Its exceptional resistance makes it useful for numerous applications and indestructible to recycling. However, associations and industries are working on more effective recycling methods for rubber to help save the environment and reduce the cost of getting new rubber.
