Sumitomo Chemical Co., Ltd. leverages its extensive expertise in polymer chemistry to offer water-based emulsions under the brand name "SUMIKAFLEX™," featuring various ethylene copolymer resins. The primary advantages of using ethylene as a copolymer monomer are as follows:
- Ethylene functions as an internal plasticizing monomer, providing an excellent plasticizing effect.
- A wide range of polymer designs can be achieved by incorporating different types of copolymerized monomers.
- Ethylene offers excellent water resistance and alkali resistance.
- It also provides outstanding weather resistance.
- Ethylene has strong compatibility with non-polar materials, such as plastics and synthetic fibers.
The SUMIKAFLEX™ series includes water-based emulsions with various polymer compositions, such as ethylene-vinyl acetate (EVA) copolymer resins and acrylic ethylene-vinyl acetate copolymer resins.
Films formed from SUMIKAFLEX™ are highly adhesive, sufficiently strong and elastic, and particularly excellent in resistance to alkalis and water, as well as durability, due to their unique polymer structure.

General Technical Information
1. What Is Emulsion?
An emulsion is a mixture of two immiscible substances. One substance (the dispersed phase) is stably dispersed in the other (the continuous phase) by a dispersed effect of the surfactant.
2. Comparison of Particle Sizes
3. Characteristics of Emulsion
4. Physical and General Characteristics of Emulsion
<Physical Characteristics of Emulsion>
Solid content, viscosity, pH
Free monomer concentration, grits (coarse particles), particle size
Particle size distribution, sedimentation
Toluene insoluble fraction, glass transition temperature (Tg), minimum film-forming temperature
<General Characteristics of Emulsion>
- Safe to use due to its water-based medium
- Exhibits thixotropic behavior (fluidity changes under shear stress)
- Forms films effectively
