Description

Polymer With Bisphenol A And Formaldehyde CAS NO 68152-68-1 is a phenolic resin polymer synthesized from bisphenol A and formaldehyde, typically known as a bisphenol A-formaldehyde resin or a phenolic novolac. This engineered polymer is valued for its excellent thermal stability, chemical resistance, and mechanical properties, making it a critical component in high-performance industrial formulations. It is primarily sought after by manufacturers in the coatings, adhesives, electronics, and composite materials industries for applications demanding durability under harsh conditions.

Application

• As a thermosetting resin in high-temperature resistant coatings and industrial paints.
• As a binding agent or modifier in friction materials, such as brake pads and clutch facings.
• As a matrix resin in fiber-reinforced composites for automotive and aerospace components.
• As an encapsulant or potting compound in electronic applications requiring insulation and stability.
• As a adhesive intermediate in the production of laminates and abrasive products like sandpaper.
• As a foundry resin for shell molding and core-making in metal casting processes.
• As a modifier for rubber and other polymers to enhance heat and chemical resistance.

Quality Control

Our Polymer With Bisphenol A And Formaldehyde is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistent performance, including analysis of key parameters such as molecular weight distribution, softening point, and residual monomer content. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 and incompatible materials. This product may be hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption.
