What is Chlorinated Polyethylene CAS 64754-90-1?

Chlorinated Polyethylene, commonly abbreviated CPE, is a chlorinated polymer made by replacing some hydrogen atoms in polyethylene with chlorine. It is supplied as a polymer additive or modifier rather than as a single small-molecule chemical, so its performance depends on grade and formulation.

Why can Chlorinated Polyethylene not be selected by CAS number alone?

CAS 64754-90-1 identifies the chlorinated polyethylene polymer family, but it does not define chlorine content, molecular weight, viscosity, particle form, or application grade. Two CPE products with the same CAS number can have very different processing and mechanical behavior, so grade selection is essential.

What does chlorine content mean for CPE performance?

Chlorine content affects polarity, compatibility, flexibility, flame retardance, and processability. Many PVC impact-modifier grades are supplied around 35% chlorine, while the broader CPE range is commonly described as about 34-44%. The correct level should match the target polymer system and performance requirements.

What are the main applications of Chlorinated Polyethylene?

CPE is widely used as an impact modifier in rigid PVC products such as profiles, pipes, fittings, sheets, and boards. It is also used in cable compounds, rubber and elastomer blends, hoses, belts, waterproof membranes, and selected construction polymer systems.

What is the difference between CPE 135A and CPE 135B?

CPE 135A and CPE 135B are commercial grade designations rather than different chemical identities. They typically differ in processing behavior, hardness, tensile properties, and end-use suitability, so the choice depends on whether the buyer needs an impact modifier, a rubber modifier, or a compound with specific processing requirements.

Which specification values are most important for industrial CPE sourcing?

The key values depend on the application, but commonly reviewed items include chlorine content, volatile matter, ash, sieve residue, bulk density, Mooney viscosity, tensile strength, Shore hardness, and thermal stability. These parameters should be compared against the buyer's processing equipment and target compound performance.

Chlorinated Polyethylene CAS 64754-90-1

Chlorinated Polyethylene CAS 64754-90-1 is a chlorinated polymer material used as an impact modifier, elastomeric modifier, and specialty polymer additive. It is commonly selected for PVC products, cable compounds, rubber blends, waterproof materials, and industrial polymer formulations requiring flexibility, durability, or improved processing performance. Chloroprene Rubber is a related chlorinated elastomer material to compare where the formulation requires a rubber base rather than a CPE modifier.

Main Applications

Chlorinated Polyethylene CAS 64754-90-1, also known as CPE, is a chlorinated polymer material used in industrial polymer modification and specialty compound production. Unlike a single small-molecule chemical, CPE is supplied in different grades, and its performance depends on factors such as chlorine content, molecular weight, viscosity, particle form, and application design.

In B2B sourcing, Chlorinated Polyethylene is commonly selected as an impact modifier, elastomeric modifier, and functional polymer additive. It is widely considered for PVC processing, rubber modification, cable compounds, hoses, sheets, waterproof membranes, and selected coating or construction material systems.

Application Area	Buyer-Relevant Use Direction
PVC Impact Modification	Used in rigid PVC profiles, pipes, fittings, sheets, and related products where impact strength and processing balance are important.
Cable and Wire Compounds	Applied in selected cable sheath or compound systems requiring flexibility, weather resistance, and polymer compatibility.
Rubber and Elastomer Blends	Used as a polymer modifier in rubber blends, hoses, sheets, and other elastomeric materials depending on formulation needs.
Waterproof and Construction Materials	May be used in waterproof membranes, modified polymer sheets, and construction-related polymer compounds.
Industrial Polymer Compounding	Suitable for compounders who require a chlorinated polymer additive with defined processing and mechanical performance requirements.

Product Specifications

Chlorinated Polyethylene is usually supplied as a white powder or granular polymer material. Because CPE is a polymer product, specification values vary by grade and intended application. Buyers should not evaluate it only by CAS number. The correct grade should be selected according to processing method, compatibility, target performance, and formulation system.

For industrial purchasing, commonly reviewed specification items include chlorine content, volatile matter, residue, bulk density, particle size, Mooney viscosity or viscosity-related indicators, tensile properties, heat stability, and compatibility with PVC, rubber, or other polymer systems. Exact values should be confirmed with the current TDS, COA, or agreed supply specification.

Packaging and Supply

Chlorinated Polyethylene CAS 64754-90-1 can be supplied in standard industrial packaging suitable for polymer additives and export shipment. Bag packaging is commonly used for polymer powder materials, while packaging details may be adjusted according to grade, shipment method, and order quantity.

For quotation and grade selection, buyers are encouraged to provide the intended application, target grade or reference grade, required quantity, packaging preference, destination country or port, and any technical specification requirements. This helps confirm whether the available CPE grade is suitable for PVC modification, rubber compounding, cable compounds, or other industrial polymer systems.

Storage and Handling

Store Chlorinated Polyethylene in a cool, dry, and well-ventilated area. Keep the package closed when not in use and protect the material from moisture, contamination, direct sunlight, and excessive heat. Avoid mixing with incompatible substances during storage or processing.

During handling, use suitable protective equipment and avoid generating excessive dust. Processing conditions should be determined by the buyer’s formulation system and production equipment. Users should review the latest SDS and technical data before large-scale production use.
