Main Areas Of Application

Coatings and Inks Industry

Microsphere foaming agents create fine foam structures, improving the thixotropy, leveling, and hiding power of coatings. They enhance the 3D texture and glossiness of inks, making printed products more attractive. Additionally, they can produce specialized coatings, such as matte and suede finishes.

Plastics and Rubber Industry

In the rubber industry, azodicarbonamide acts as a blowing agent to manufacture various rubber foam products, such as shoe soles, tires, sealing strips, soundproofing materials, and vibration damping pads. These products exhibit excellent elasticity, abrasion resistance, and aging resistance, finding applications in the automotive, footwear, construction, and transportation industries.

Other Industries

In plastic and rubber products, microsphere foaming agents reduce material density, enhancing lightweight properties. They also improve sound and thermal insulation and increase toughness and impact resistance. For example, they can create microcellular rubber products like shoe soles and soundproofing materials.

Construction Materials Industry

Used to manufacture lightweight, high-strength building materials such as foamed concrete and gypsum boards. These materials offer excellent insulation properties, reduce building weight, and enhance earthquake resistance.

Textile and Leather Industry

Creates textiles and leather products with 3D and soft textures. Adding microsphere foaming agents generates fine foam structures on the surface, enhancing comfort and tactile quality.

Market and Development Trends

With the growing emphasis on environmental protection and sustainable development, eco-friendly microsphere foaming agents have a bright future. As technology advances and markets expand, the performance of microsphere foaming agents will continue to improve, and their application areas will broaden further.
In summary, the microsphere Foaming Agent is an efficient, environmentally friendly and multifunctional foaming agent with wide applications in many fields. During use, attention should be paid to storage conditions and usage methods to ensure its foaming effect and product quality.
