Description

Lignin, Polymer With Formaldehyde And Phenol CAS NO 37281-91-7 is a synthetic phenolic resin derived from lignin, a major component of wood. This engineered polymer is valued for its enhanced thermal stability, mechanical strength, and adhesive properties compared to unmodified lignin. It serves as a critical performance additive and binder in industries requiring durable, bio-based polymeric materials.

Application

• Wood Adhesives & Binders: A key component in the formulation of plywood, particleboard, and fiberboard adhesives, offering an alternative to pure phenol-formaldehyde resins.
• Foundry Sand Binders: Used as a core and mold binder in metal casting for its excellent thermal resistance and binding strength.
• Friction Materials: Acts as a binding agent in brake pads and clutch facings, contributing to heat stability and reduced wear.
• Thermoset Molding Compounds: Incorporated into phenolic molding compounds for electrical components, automotive parts, and appliance handles.
• Oil Well Drilling Additives: Functions as a fluid loss control agent and stabilizer in drilling mud formulations.
• Rubber Reinforcement: Used as a reinforcing agent and tackifier in certain rubber compounds to improve mechanical properties.
• Carbon Black Dispersant: Aids in the dispersion of carbon black in rubber and ink systems.
• Industrial Grinding Wheels: Serves as a resinoid binder in abrasive wheels and cutting tools.
