Chlorinated paraffin is a mixture of chlorinated alkanes prepared by chlorination reaction with liquid paraffin as raw material. Different types of products are classified according to the chlorine content. Chlorinated paraffin 52 is based on the average carbon chain number of 12 or 15 liquid paraffin is used as a raw material, and a product with a chlorine content of 52%±2%. After learning about chlorinated paraffin 52, let's discuss the use and characteristics of chlorinated paraffin 52 with the editor!

One, Chlorinated Paraffin 52 uses

1. Chlorinated paraffin 52 has the property of being insoluble in water, so it can be used as a cost-reducing filler in coatings, increasing the cost performance and waterproof and fireproof properties.

2. Used in PVC products as plasticizer or auxiliary plasticizer, its compatibility and heat resistance are better than chlorinated paraffin-42.

3. It can also be used as an additive in rubber, paint, and cutting oil to play a role in fire resistance, flame resistance and improve cutting accuracy.

4. It can also be used as an anticoagulant and anti-extrusion agent for lubricating oil.

5. Used in paints, chlorinated rubber and styrene-butadiene resin coatings, in plastics, as flame retardants, binders, cements and fillers.

6. It can also be used as a lubricating additive, and it also has moisture resistance and chemical corrosion resistance.

7. Used as a plasticizer for chloroprene rubber, nitrile rubber, SBS and other adhesives and sealants, chlorinated paraffin 52 plasticized silanized polyurethane sealant, with high elongation at break and good elasticity.

2. Characteristics of Chlorinated Paraffin 52

1. Chlorinated paraffin is golden yellow or amber viscous liquid, non-flammable, non-explosive, and extremely volatile. It is soluble in most organic solvents, but insoluble in water and ethanol. When heated to above 120℃, it will slowly decompose by itself, which can release hydrogen chloride gas, and the oxides of iron, zinc and other metals will promote its decomposition. Chlorinated paraffin is an auxiliary plasticizer for PVC. Low volatility, non-flammable, odorless, and non-flammable. This product replaces part of the main plasticizer, which can reduce product cost and reduce combustibility. Mainly used for PVC cable material and water pipe, floor material, film, artificial leather, etc.

2. The plasticizing performance of chlorinated paraffin 52 is lower than that of the main plasticizer, but it can increase the electrical resistance and flame resistance, and can improve the tensile strength. Its disadvantages are poor aging resistance and low temperature resistance, poor use of secondary recycling and high viscosity, but under the current lack of primary plasticizers and high prices, it still enjoys the market. Certain status.

3. Chlorinated paraffin 52 can be mixed with related esters. After mixing, it can form a kind of plasticizer. In addition, it also has certain flame retardant and lubricating characteristics. It can even be used when necessary. To a certain degree of antiseptic effect.

4. The production capacity of chlorinated paraffin 52 substances is very large. In the application process, thermal chlorination methods and catalytic chlorination methods are mainly used. In special cases, photochlorination methods are also used.
