FDT Concentric Double Shaft Agitator: Ideal Process Equipment for the Production of Neoprene Adhesive
Jul 10, 2026
In the field of modern industrial bonding, rubber adhesives are widely used for bonding rubber with materials such as metals, plastics, fabrics, leather, and wood due to their excellent elasticity. They play an important role in industries such as aircraft manufacturing, automobiles, construction, and light industry. Among numerous rubber adhesives, chloroprene rubber adhesive is undoubtedly the most widely used and produced type, accounting for over 70% of the total synthetic rubber adhesive.
The chloroprene rubber adhesive is formed by addition polymerization of chloroprene, and its molecular structure contains highly polar chlorine (- Cl) groups, which endow it with excellent initial adhesion, resistance to sunlight, ozone aging, oil and solvent resistance, and other outstanding properties. However, due to its complex formula system (including rubber, vulcanizing agents, accelerators, anti-aging agents, reinforcing agents, fillers, and solvents, etc.), and the high risk of rubber burning caused by vulcanizing agents such as magnesium oxide and zinc oxide during mixing, coupled with poor storage stability, this places extremely high demands on the mixing efficiency and temperature control capability of production equipment.
Faced with the complex formula and strict process requirements of chloroprene rubber adhesive, FDT Concentric Double Shaft Agitator, as an efficient dispersing and mixing equipment designed specifically for the adhesive field, has demonstrated excellent process adaptability.
Dual-axis collaboration for efficient dispersion and mixing
The core structure of the FDT Concentric Double Shaft Agitator consists of a scraper stirrer and a high-speed disperser. Two sets of agitators work simultaneously, and under strong shear and mixing forces, they can quickly homogenize and mix chloroprene rubber, reinforcing fillers, and various additives. In order to adapt to the viscosity and density of different formulations (such as filler type, resin-modified type, or room temperature vulcanization type), the equipment provides flexible configuration schemes: the agitator can choose frame or half-frame type, and the dispersing disc provides multiple options such as double disc, single disc, and Neumann disc to accurately match the process requirements.
No dead corner mixing, ensuring formula uniformity
The chloroprene rubber adhesive is prone to adhering to the kettle wall during the mixing process, resulting in uneven pre-reaction of local magnesium oxide or resin. The FDT Concentric Double Shaft Agitator is equipped with PTFE scrapers, which can tightly adhere to the container walls that have been precision turned and mirror polished, continuously scraping off wall sticking materials. This design completely eliminates mixing dead corners and material residues, significantly improving mixing efficiency and effectively preventing burning caused by local material accumulation, ensuring the storage stability of the adhesive.
Heavy-duty structure to cope with high-viscosity challenges
For resin-modified or high-solid-content chloroprene rubber adhesives, the FDT Concentric Double Shaft Agitator adopts a heavy-duty and sturdy structural design. The large-area bed board is directly buried underground and equipped with a bolt-fixed agitator and spindle, ensuring extremely high stability of the equipment when processing materials with viscosity up to 100000 CPS. The precise mechanical design enables the equipment to operate without vibration and with low noise in large-scale production, providing a stable production environment for the workshop.

Flexible operation and multifunctional expansion
At the operational level, the FDT Concentric double-shaft agitator supports hydraulic lifting and swinging mechanisms, making it extremely convenient to rotate between single or multiple tanks. The equipment can choose between fixed speed and variable frequency drive to meet the shear requirements of chloroprene rubber at different dissolution stages. In addition, the device also supports vacuum dispersion or mixing function, which can extract solvent volatiles and material bubbles in a closed environment, further improving the density and product quality of the adhesive.
In summary, the FDT Concentric double shaft agitator perfectly fits the production process of chloroprene rubber adhesive with its efficient biaxial mixing mechanism, seamless scraping design, and stable heavy-duty structure. It not only solves the pain points of complex formula mixing and easy burning in the industry, but also provides strong equipment support for chloroprene rubber production in the fields of footwear, automobiles, and construction.
