What Are the Advantages of DMC Catalyst?

DMC catalyst is a new type of high-performance catalytic olefin oxide ring-opening polymerization catalyst, suitable for synthesis of olefin oxide polyether containing 1-6 functional groups. DMC catalyst manufacturers usually use low molecular weight organic complexing agents. The complexing agents beneficially affect the activity of the catalyst for epoxide polymerization.

The production of polyether with DMC catalyst has the following advantages:

Low production and running costs

1) No post-processing process and faster reaction speed increase the production capacity of the device by several times.

2) No post-treatment process reduces equipment investment, unit product energy consumption and water consumption, unit product solid waste and waste water production, and improves product yield.

3) It can produce higher molecular weight products with molecular weight of more than 2000 per mole of hydroxyl group.

4) The produced polyether has the characteristics of narrow molecular weight distribution, few by-products, low unsaturation and low odor. When it is used in the PU field (elastomers, soft foams, high resilience foams, coatings, sealants), various aspects of properties such as tensile, elongation, and compression are greatly improved.

The Difference Between Nitrile Rubber and NBR LatexThe Difference Between Nitrile Rubber and NBR Latex

Affected by public health incidents, NBR latex is like a dark horse that has attracted the attention of the international market. Nitrile rubber and NBR latex are very different in use. 1. The difference in performance between nitrile rubber and NBR latex Nitrile rubber is produced by emulsion polymerization of butadiene and acrylonitrile. Nitrile rubber is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high abrasion resistance, good heat resistance, and strong adhesion. . Its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity. Nitrile rubber is mainly used to make oil-resistant rubber products. Carboxylic nitrile latex is obtained by introducing methacrylic acid or methacrylate ternary copolymer during polymerization. Since the carboxyl nitrile nitrile latex introduces a more polar carboxyl group into the molecular backbone, it furt...

What is GLycolic Acid?

We like to focus on the ingredients of beauty products. But we prefer to touch the product and explore whether it really works. Alpha hydroxy acid is also known as AHA. It includes glycolic acid , lactic acid and citric acid. These products do not meet the needs. Now we analyze the most popular ingredient in the world - glycolic acid. Glycolic acid is a naturally occurring substance that is added to skin care products. It is good for the skin and restores skin elasticity and moisturization. The original state of glycolic acid is a powder composed of colorless crystals. It is tasteless. Let's first understand its benefits and its related products. The Benefits of Glycolic Acid Glycolic acid is very effective for skin treatment because of its high purity. The premise is safe and correct use. Many skin care products contain glycolic acid. Sensitive muscles can also be used. Glycolic acid is non-irritating and it can be used in skin care. Add more glycolic acid t...

Difference Between Sulfate And Sulfonate In Shampoo

Sulfates and sulfonates have two things in common. First, they're all anionic surfactants. Second, they are often used for personal care applications. But there are many differences. They have different molecular mechanisms. They have different functions and they have different raw materials. Sulfates Sulfate is a compound. It has carbon bonds and oxygen and sulfur bonds. They include substances such as sodium lauryl sulfate and sodium lauryl ether sulfate. At low pH, these substances plus the c-o-s bond hydrolyze to produce alcohol and inorganic sulfate. At a high pH, sulfate is stable in the base and, if ethoxylated to a relatively high level, produces a low-foaming alkali-soluble surfactant. Sulphates can be prepared by reaction of fatty alcohol or fatty alcohol ethoxylates with reagents such as SO3 or chlorosulfonic acid (CSA). The reason shampoo becomes thick foam in the shower is that it contains sulfate. Most shampoos and household cleansers contain su...
