Chlorinated Rubber is a marvel of chemical engineering, transformed from its natural or synthetic rubber origins into a highly effective industrial material. Its unique properties are not solely inherent but are often optimized through careful formulation with various additives and modified resins. Understanding these technical nuances is key to leveraging Chlorinated Rubber’s full potential in applications ranging from protective coatings to adhesives and inks. NINGBO INNO PHARMCHEM CO.,LTD. possesses deep expertise in the chemistry and formulation of Chlorinated Rubber, ensuring the delivery of high-performance products.

The core of Chlorinated Rubber’s functionality lies in its chemical structure, typically featuring a chlorine content of 62-67%. This high degree of chlorination renders the polymer inert, significantly reducing its unsaturation and increasing its resistance to oxidation and UV degradation. When dissolved in appropriate solvents such as aromatic hydrocarbons, esters, ketones, or chlorinated hydrocarbon solvents, it forms a stable solution. The common practice is to dissolve it in xylene to create a 40% solution, which serves as the base for many formulations.

To enhance the performance of Chlorinated Rubber, particularly its flexibility and adhesion, various modifiers are incorporated. Plasticizers, such as chlorinated paraffin, are essential as they combat the inherent brittleness of the pure polymer film. Chlorinated paraffin is highly compatible and offers excellent pigment wetting and dispersion. Other plasticizers like dibutyl phthalate or tricresyl phosphate can also be used, depending on the desired properties. The ratio of Chlorinated Rubber to plasticizer is critical for achieving a balance of tensile strength, elongation, and water vapor permeability.

Modified resins are also frequently blended with Chlorinated Rubber to improve specific characteristics like gloss, light stability, and mechanical properties. Common co-resins include alkyd resins (medium to long oil), polyurethane resins, acrylic resins, epoxy resins, and phenolic resins. These blends allow formulators to tailor the coating or adhesive for specific end-uses. For example, modifying with acrylic resins and using phthalates as plasticizers can improve the weather resistance, especially for white or light-colored topcoats.

The formulation also involves additives like anti-settling agents to prevent pigment agglomeration and wetting dispersants to improve pigment dispersion and stability. Defoamers are often included to prevent bubble formation during application, especially with spray methods. For formulations modified with alkyd resins, specific driers are added to accelerate the oxidation curing process. NINGBO INNO PHARMCHEM CO.,LTD. meticulously controls these formulations to guarantee product quality and consistency.

The performance characteristics derived from these formulations are remarkable: rapid drying, excellent adhesion, superior chemical and water resistance, and good flame retardancy. These attributes make Chlorinated Rubber a go-to material for demanding applications. When you choose to buy Chlorinated Rubber chemical from NINGBO INNO PHARMCHEM CO.,LTD., you are assured of a product backed by rigorous technical understanding and quality control, ensuring optimal results for your industrial needs, whether it’s for protective coatings or specialized adhesives.
