Dipentaerythritol

Introduction

Dipentaerythritol is a polyol with six hydroxyl functional groups, high molecular weight and excellent thermal stability. As a high-functionality chemical raw material, dipentaerythritol is widely used in many industries such as coatings, inks, plastics, lubricants, flame retardant materials, etc., especially in the synthesis of high-performance polymers.

Advantages

High functionality
Dipentaerythritol contains 6 hydroxyl functional groups in the molecule, which gives it high reactivity. When synthesizing multifunctional polymers such as polyester, alkyd resin, polyurethane, etc., it can provide more crosslinking points, which helps to improve the structural integrity and physical properties of the products, such as mechanical strength, adhesion and durability.

Good thermal stability and oxidation resistance
The molecular structure of dipentaerythritol is relatively stable under high temperature conditions, and has certain heat resistance and antioxidant ability. Therefore, it has good applicability in applications with high thermal stability requirements such as high-temperature lubricating oil esters and electronic materials, which helps to extend the performance retention period of the material during use.

Low volatility and high molecular weight
Compared with pentaerythritol, dipentaerythritol has a higher molecular weight and lower volatility. This feature helps to reduce material loss and volatile organic compound (VOC) emissions during processing, which is conducive to improving environmental friendliness and product safety performance. It is particularly suitable for environmentally friendly coatings, inks and plasticizer systems.

Good weather resistance and hydrolysis resistance
In coating and resin applications, dipentaerythritol helps improve the material's resistance to external environments such as light, heat, and moisture, and can enhance the product's anti-yellowing and moisture resistance. It is suitable for outdoor paints, cable coating materials, plastic additives, and other occasions that require weather resistance.

Good compatibility and processing adaptability
Dipentaerythritol has good compatibility with a variety of commonly used reactants such as acids, anhydrides, and isocyanates, and can adapt to a variety of reaction conditions and process environments. It exhibits good processing fluidity and film-forming properties during the actual synthesis process, which is conducive to process control and product performance optimization.
