Description

Formaldehyde, Polymer With Oxirane And Phenol is a phenolic resin intermediate produced by the reaction of formaldehyde, phenol, and ethylene oxide (oxirane). This compound is valued for its role in creating high-performance, cross-linked polymer networks with excellent thermal stability and chemical resistance. It is primarily sought by manufacturers in the adhesive, coating, molding compound, and foundry resin industries for producing durable thermoset materials.

Application

• Foundry Binder Systems: A key resin component for shell molding and cold-box processes in metal casting.
• Thermoset Molding Compounds: Used in the production of electrical components, automotive parts, and appliance housings.
• Industrial Adhesives & Laminates: Serves as a cross-linking agent in phenolic and epoxy-based adhesives for wood, abrasives, and friction materials.
• Protective Coatings: Imparts chemical and heat resistance in industrial maintenance and automotive primer coatings.
• Friction Material Binders: Used in the formulation of brake pads and clutch facings.
• Abrasive Wheel Binders: Acts as a resin binder in grinding and cutting wheels.
• Encapsulation & Potting Compounds: For electronic components requiring environmental protection and insulation.
• Rubber Reinforcement: Used as a tackifier and reinforcing resin in certain rubber compounds.

Quality Control

Our production of Formaldehyde, Polymer With Oxirane And Phenol follows stringent in-process controls to ensure batch-to-batch consistency for industrial applications. Key parameters such as viscosity, epoxy equivalent weight (EEW), hydroxyl value, and residual monomers are monitored. A Certificate of Analysis (COA) detailing the specific grade's properties is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents. Under these conditions, the product is typically stable for 12-24 months from the date of manufacture.
