✓ Official Distributor
DN Automotive (formerly Dong-A Tire) leverages its long-established rubber compounding technology to supply rubber CMB (compound rubber) used in a wide range of rubber parts across automotive, electronics, footwear and general industrial products.


Applications
CMB Compound · Main Polymer Types
| Polymer Type | Characteristics | Main Uses |
|---|---|---|
| EPDM | High resistance to water, ozone and offering excellent electrical insulation, widely used as a general-purpose rubber | Automotive W/Strip, sponge, gaskets, various PACKING, wire insulation, hoses, etc. |
| NR | Raw rubber with outstanding mechanical strength, low heat build-up and excellent resistance to repeated fatigue, widely used for anti-vibration rubber | Tires, anti-vibration rubber, rubber belts, etc. |
| SBR | Easy to process with excellent durability, used as a substitute for NR | Rubber mats, coloring applications, etc. |
| BR | Excellent abrasion resistance and elasticity with good low-temperature flexibility. Blended with SBR, NR and others to improve properties | Tire tread, shoe SOLE, etc. |
| NBR | Outstanding resistance to mineral oils (oil resistance) | Fuel hoses, oil seals, safety footwear, etc. |
| IIR | Low gas permeability and chemical reactivity, with low rebound elasticity and good vibration absorption | Automotive W/Strip, sponge, gaskets, various PACKING, wire insulation, hoses, etc. |
| CR | Low flammability, good adhesion and oil resistance, and strong weathering resistance. Excellent rubber elasticity and mechanical strength | Fuel hose outer covers, belts, etc. |
| Other | Custom rubber products synthesized to the customer's requirements or with our own proprietary formulations | Custom development for customers |
Custom Supply
CMB is not a fixed-specification product but a custom compound made to the properties the customer requires (hardness, heat resistance, oil resistance, cold resistance, flame retardancy, color, etc.). Dongwoo Solution accurately identifies your requirements through consultation and on-site visits, then designs and delivers the optimal compound to match.
Supply Process
We discuss the rubber parts you need and their intended applications.
Through on-site visits we determine the operating environment and required properties (hardness, heat/oil resistance, flame retardancy, etc.).
We design the optimal CMB compound formulation to match your requirements.
After quality verification, we deliver a compound tailored to your required properties.
