Selecting a functional material is not only about choosing a product name or resin type. It is often more effective to begin with the challenge you want to solve and the process where that challenge occurs. For example, you may need to reduce solvent use, review a foaming process, make molded parts lighter, reduce dust during handling, or adjust toughness and adhesion in a thermoset resin system.
This page introduces SEKISUI Specialty Chemicals’ polyvinyl acetal resins, specialty acrylics, and expandable microspheres as starting points for more detailed material evaluation.
With higher environmental standards and more attention to workplace safety, manufacturers are thinking about moving from solvent-based to water-based systems. But changing materials means looking at more than just performance. Things like how well the coating sticks, how stable it is, how it dries, how it covers, and whether it works with current equipment all need to be checked.
SEKISUI Specialty Chemicals helps you find resins and materials for water-based products that make them safer, lower VOCs, and suit your needs. The main solution page shows the benefits and practical ways to create more eco-friendly formulas.
Chemical blowing agents are widely used to add lightweight, insulation, or cushioning properties to resins, rubber, coatings, and sealants. Depending on the application and region, however, regulatory trends such as those related to ADCA, residual by-products, odor, variation in cell size or distribution, and more complex additive design may need to be considered.
ADVANCELL™ expandable microspheres are physical foaming materials that expand when heated. They can support foaming designs that account for closed-cell formation, uniform expansion, and reduced concerns about residual by-products.
ADVANCELL™ is an expandable microsphere material compounded into resins to form fine closed-cell structures when heated. It works with PVC, PP, PE, elastomers, and composites, as well as extrusion, injection molding, blow molding, and coating. SEKISUI Specialty Chemicals supports foaming design based on your application, base material, molding conditions, and target properties. We help organize expected effects and evaluation items before detailed material testing.
Thermoset resins, including epoxy resins, are widely used when rigidity, heat resistance, and dimensional stability are needed. However, internal stress during curing or thermal history can lead to brittleness, cracking, interfacial delamination, and difficult handling during processing.
S-LEC™ BK Series is a PVB-based modification material. It can be added as a third component to matrix resin systems. Its flexible molecular chain structure and polar groups help adjust the balance of toughness, adhesion, and processability. Formulation flexibility is maintained.
Product performance is only part of the decision when evaluating resin materials. Manufacturers must also consider consistent feeding, reducing dust and scattering, and minimizing variation during dissolution or dispersion.
SEKISUI Specialty Chemicals offers granulated grades mainly for selected PVB products, as well as conventional powder types. Granulation reduces dust during feeding and handling, creating a cleaner environment and lowering equipment contamination. Availability depends on product and grade, so confirm based on your application and process.
