Chlorination Mini-Class Series (2) - Characteristics of Chlorinated Rubber

09 Apr,2025

Chlorinated rubber is a product obtained through chlorination modification of natural or synthetic rubber.

Chlorinated rubber is a product obtained through chlorination modification of natural or synthetic rubber. Due to its unique chemical structure and the introduction of chlorine atoms, chlorinated rubber possesses many excellent properties.

1.Outstanding Corrosion Resistance

The molecular chain structure of chlorinated rubber is fully saturated, containing no reactive groups such as double bonds, endowing it with exceptional corrosion resistance. It demonstrates excellent tolerance to various corrosive chemicals including acids, alkalis, salts, chlorine gas, H₂S, and SO₂.
Chlorinated rubber resin coatings exhibit superior resistance to medium penetration, delivering outstanding performance in both corrosion protection and waterproofing applications, thereby ensuring long-term protective efficacy.

2.Exceptional Chemical Stability‌

Chlorinated rubber resin maintains excellent chemical inertness in both acidic and alkaline environments, demonstrating outstanding performance particularly in concrete corrosion protection. Its coating film exhibits extremely low permeability to water vapor and oxygen, offering superior resistance to water, salts, alkalis, and various corrosive gases.

3.Excellent Flame Retardancy and Mildew Resistance

Chlorinated rubber's high chlorine content provides inherent flame-retardant and anti-mold properties due to its Cl-functional groups, resulting in products with superior fire safety and microbial resistance.

4.Excellent Elasticity and Durability

Chlorinated rubber resin coatings demonstrate outstanding deformation resistance, extended service life, high tensile strength, and significant elongation capacity, effectively resisting substrate shrinkage and cracking. The seamless, joint-free characteristics of this highly elastic material form a continuous closed protection system, ensuring secure adhesion to various substrates.

5.Superior Adhesion Performance

The highly polar C-Cl bonds in chlorinated rubber provide exceptional adhesion to diversematerial surfaces including steel, aluminum alloys, cement, and wood. This enables tight bonding with substrate to form durable, high-strength coatings.

6.Non-Toxic and Odorless

Chlorinated rubber resin is non-toxic and odorless, posing no skin irritation risks or health hazards to humans. During application, these characteristics eliminate concerns over harmful gas inhalation, ensuring a worker-friendly construction environment.
As a product, its non-toxic and odorless nature enhances safety during storage and transportation, requiring no special protective measures and facilitating convenient logistics handling.

These excellent properties make chlorinated rubber an ideal material for multi-field applications. The next section will detail its specific applications across various industrial fields.‌
