Because of its resistance to oil, heat, flame, and its durability against the elements, chlorinated polyethylene (CPE) is typically used to insulate wire and control cables for industrial power plant applications, appliance wire, lead wire, coil leads, transformer leads, and motor lead wire.

What is CPE material?
CPE is the standardized acronym for thermoplastic chlorinated polyethylene elastomer, which is produced by chlorination of polyethylene. The chlorine content can be 15 to 30% by weight.
What is XLPE cable?
1.2.1 Description of XLPE cable
XLPE is an acronym for cross linked polyethylene. XLPE is a thermosetting polymer meaning that the material (polyethylene (PE)) is cured under heat and in that process forms bonds in all directions forming a three dimensional matrix.
What is CPE wire?
CPE – Chlorinated Polyethylene (CPE) is one of the few polymers that is available as both a thermoplastic and a thermoset jacket (thermoset CPE would be a cross-linked version). The thermoplastic CPE jacket has excellent oxidation, heat, oil, weather/sun and flame resistance.
Is CPE a thermoset?
Chlorinated Polyethylene, also referred to as CPE, is considered a thermoplastic material. It is also available in a cross-linked or thermoset version. The thermoplastic version is most commonly used. CPE insulation provides excellent flame and chemical resistance.
What is CPE in PVC?
Chlorinated polyethylene (CPE), an uncrosslinked rubber impact modifier for rigid PVC applications, allows the processor to significantly increase the filler concentration without suffering loss of impact strength or processing penalties.
Is CPE a rubber?
1) CPE is a saturated rubber with excellent chemical properties, such as resistance to thermal oxygen aging, ozone aging, and acid and alkali resistance. 2) CPE has excellent oil resistance, such as resistance to ASTM 1 oil and ASTM 2 oil. Its oil resistance is comparable to that of NBR.
Which is better XLPE or PVC?
Water Proof Performance in Application Environment: PVC insulated cable is better than the XLPE insulated cable. Environment Protection aspect: For XLPE is not containing chlorine which will release toxic gases once burn, so XLPE insulated Cable is environment friendly compared with PVC insulated Cable.
Is XLP and XLPE the same?
CROSS-LINKED POLYETHYLENE(XLP) is a material which has greater resistance to environmental stress cracking, cut-through, ozone, solvents and soldering than either low or high density polyethylene. Sometimes designated as XLPE. Can be cross-linked either chemically or irradiated.
Is XLPE waterproof?
In order to prevent the penetration of moisture and also to extend the duration of life, the XLPE insulated medium voltage cables are designed with longitudinally waterproof shielding including an additional swell tape and PE outer jacket.
What is XLPE insulation?
XLPE or Cross-linked polyethylene is a thermoset insulation material. Crosslinking polymers is a process which changes the molecular structure of the polymer chains so that they are more tightly bound together and this crosslinking is done either by chemical means or physical means.
What is EPR cable?
What is EPR Cable? EPR or Ethylene Propylene Rubber is a copolymer made from, as indicated by its name, ethylene, and propylene. It’s also called an elastomer. This material is mainly used in electrical cables for insulation as its dielectric strength is higher than both ethylene and propylene separately.
Is CPE thermoset or thermoplastic?
Chlorinated Polyethylene (CPE): CPE can be formulated in both thermoset and thermoplastic varieties. Thermoplastic CPE can resist heat and flame damage, weather elements, oxidation, and oils.
What is thermoset cable?
The plastic or polymers used in cable insulation are either thermoplastic or thermoset. Thermoplastic material is softened by heating and can be shaped, with the shape then maintained by cooling.
Is XLPE a thermoset?
Cables that are insulated with XLPE can run a higher current in the conductors. What allows XLPE to endure these temperatures is that it is a thermoset material, while PVC is a thermoplastic.
What is thermoset insulation?
What is thermoset insulation? Thermoset insulation is made of a material that gains strength when heated. However, these materials cannot be reheated or change shape without damaging the material’s structure. Thermoset is basically a cured polymer. Rubber and synthetic rubber are common thermoset materials.
What is the difference between CPE and PVC?
There are some important differences between the two polymers. For example, PVC must be plasticized in order to be flexible. Over time the plasticizers migrate out of the PVC which can result in the membrane becoming brittle. CPE is a naturally flexible elastomer and requires no plasticizers.
What is CPE 135A?
Chlorinated Polyethylene CPE-135A, which are widely used for various Thermoplastic and Elastomer applications. These chemicals also perform many other functions such as, impact modifier for vinyl siding and window profiles and for PVC pipes, and electrical connectors and fittings.
What is chlorinated plastic?
chlorinated plastic materials means packaging materials made of polyvinyl chloride (PVC) or other chlorinated compounds. Vinyl chloride is a known carcinogen; Sample 1. chlorinated plastic materials means packaging materials made of polyvinyl chloride (PVC) or other chlorinated compounds; Sample 1.
Does PVC dissolve in water?
Polyvinyl chloride (colloquial: polyvinyl, or simply vinyl; abbreviated: PVC) is the world’s third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene).
Polyvinyl chloride.

What is polyethylene chloride?
Chlorinated Polyethylene is a family of thermoplastics that are produced by the chlorination of high-density polyethylene. Chlorine content can be as high as 70% by weight but most grades have chlorine content in the 25% up to 42% range.
