Lignin, extracted from wood and other materials, is expected to have high strength and high heat resistance due to its structure containing benzene rings. Phenolic resins, which use petroleum-derived phenol that also contains benzene rings, have similar properties and have been widely used in casting and molding fields as heat-resistant materials for a long time. By modifying a portion of phenolic resin with modified lignin, it becomes possible to maintain the properties of phenolic resin while imparting new characteristics, thereby achieving carbon neutrality through sustainable natural resources. 【Features】 ■ High heat resistance ■ Versatile moldability ■ Flexibility is imparted ■ Improved electrical insulation ■ Enhanced water resistance *For more details, please refer to the PDF document or feel free to contact us.

We have successfully developed a powdered resol-type phenolic resin with thermal self-curing properties that does not contain hexamine (a curing agent), which is a major cause of odor generation. The content of toxic and hazardous substances such as phenol and formaldehyde is below regulatory limits and therefore not applicable. It can be compounded with various fillers. Please feel free to contact us if you have any requests. 【Features】 ■ Powdered resol resin ■ Compared to novolac resin, ammonia generation is reduced to about 1/20 ■ High moisture absorption suppression, anti-agglomeration, and anti-blocking properties ■ Resin properties: Gel time (around 50 seconds), softening point (over 105°C), flow (around 20mm) ■ Bending strength is equivalent *For more details, please refer to the PDF document or feel free to contact us.
