Description

Formaldehyde, Polymer With Methylphenol And Phenol is a synthetic phenolic resin, a versatile thermosetting polymer formed by the condensation reaction of formaldehyde with a blend of phenol and methylphenol (cresol). This compound is valued for its excellent thermal stability, chemical resistance, and strong adhesive properties, making it a critical intermediate in high-performance industrial applications. It is primarily utilized by manufacturers in the coatings, adhesives, molding compound, and foundry industries seeking durable and reliable polymeric materials.

Application

• Foundry Binders and Core Sands: As a key component in no-bake and cold-box foundry binder systems for metal casting, providing excellent dimensional accuracy and shake-out properties.
• Friction Materials: Used as a bonding resin in the production of brake pads, clutch facings, and other friction materials, offering high heat resistance and durability.
• Abrasive Products: Serves as a binder in grinding wheels, sandpaper, and other abrasive tools, ensuring grain retention and structural integrity under stress.
• Thermoset Molding Compounds: A fundamental resin for phenolic molding compounds used in electrical components, appliance handles, and automotive parts.
• Industrial Adhesives and Laminates: Employed in the formulation of adhesives for wood, plywood, and laminated plastics, delivering strong, waterproof bonds.
• Refractory Materials: Acts as a binder in refractory bricks and monolithic linings for furnaces, providing cohesion and thermal stability.
• Rubber Reinforcing Resins: Used to modify and reinforce rubber compounds, improving hardness, modulus, and heat resistance.
• Coating and Insulation Varnishes: Incorporated into insulating varnishes and protective coatings for electrical windings and components.
