peculiarity

Chlorinated paraffin is a golden yellow or amber thick liquid, non-flammable, non-explosive, very volatile. Soluble in most organic solvents, insoluble in water and ethanol. Heating to more than 120 ° C slowly decompose, can release hydrogen chloride gas, iron, zinc and other metal oxides will promote its decomposition. Chlorinated paraffin is the auxiliary plasticizer of polyvinyl chloride. Low volatility, non-flammable, odorless, no. This product replaces part of the main plasticizer, can reduce product cost, and reduce flammability. Mainly used in PVC cable material and water pipe, floor material, film, artificial leather and so on.

The plasticizer of chlorinated paraffins is lower than that of main plasticizers, but it can increase the electric edge and fire resistance, and can improve the tensile strength. Its disadvantage is that the aging resistance and low temperature resistance is poor, the secondary recovery and reuse effect is also poor, the viscosity is large, but in the current main plasticizer shortage and expensive conditions, it still enjoys a certain position in the market.

Chlorinated paraffin wax can be mixed with related ester substances, after mixing can form a plasticizer, in addition, it also has a certain flame retardant and lubrication characteristics, and even if necessary, can also play a certain anti-corrosion role.

The production capacity of chlorinated paraffin is very large, and the application process is mainly based on thermal chlorination method and catalytic chlorination method, and in special cases, photochlorination method will be used.

use

1, chlorinated paraffin has the characteristics of insoluble in water, so it can be used as a filling material in the paint to reduce the cost, increase the cost performance and waterproof and fireproof characteristics.

2, used for PVC products, plasticizer or plasticizer.

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

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

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

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

7, used as a plasticizer for neoprene rubber, nitrile rubber, SBS and other adhesives and sealants, chlorinated paraffin plasticized silanized polyurethane sealants, high elongation at break, good elasticity.
