Description

Formaldehyde, Polymer With Dimethylphenol is a synthetic phenolic resin produced by the polycondensation of formaldehyde with dimethylphenol. This specialized polymer is valued for its excellent thermal stability, chemical resistance, and adhesive properties, making it a critical intermediate in high-performance industrial applications. It is primarily utilized in sectors requiring durable, cross-linked materials, such as advanced composite manufacturing, specialty adhesives, and high-temperature molding compounds.

Application

• High-Performance Adhesives & Binders: A key resin component for wood composites, friction materials (brake pads, clutch facings), and abrasive products (grinding wheels, sandpaper).
• Thermoset Molding Compounds: Used in the formulation of phenolic molding powders for electrical components, appliance handles, and automotive parts requiring heat and flame resistance.
• Foundry Resins: Serves as a binder in shell molding and core-making processes for metal casting, providing excellent dimensional stability and shake-out properties.
• Laminates & Composites: Impregnated into paper, fabric, or glass fiber to produce industrial laminates for electrical insulation and decorative surfaces.
• Coating & Encapsulation: Formulated into protective coatings and potting compounds for electronic components due to its good dielectric properties and chemical inertness.
• Rubber Reinforcement: Acts as a tackifying and reinforcing resin in rubber compounding to improve adhesion and mechanical properties.
• Oilfield Chemicals: Utilized in the synthesis of resins for well consolidation and sand control applications.

Quality Control

Our Formaldehyde, Polymer With Dimethylphenol is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters such as softening point, free phenol content, gel time, and solubility to ensure consistency and performance for your specific application. Certificates of Analysis (COA) are provided with every shipment, and we can support compliance with relevant industry standards upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources, open flames, and incompatible materials such as strong oxidizers. The product may be hygroscopic; ensure containers are sealed after use to prevent moisture absorption.
