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 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.
Is CPE toxic?
Chlorinated polyethylene (CPE) is a material obtained through the substitution of hydrogen atoms with chlorine atoms in high-density polyethylene (HDPE). CPE exists as a white powder. It is non-toxic and tasteless.
What is the most flexible cable jacket material?
PVC. Polyvinyl Chloride (PVC) is the most common jacket material used in cabling today. PVC is a cost-effective option yet still flexible and rugged enough for many work sites.
What is the purpose of cable jacket?
A jacket is the outermost layer of a cable whose primary function is to protect the insulation and conductor core from external physical forces and chemical deterioration. In a sense, the cable jacket is the first line of mechanical defense for a cable by protecting its inner components.
What is CPE membrane?
A waterproofing membrane used under a full mortar bed installation of ceramic tile, dimension stone or terrazzo tile. • Made from Chlorinated Polyethelyne (CPE) – Will not rot, crack or rust.
Is CPE biodegradable?
Specially formulated to biodegrade in landfill through a microbial process. CPE Glove offers basic protection for hygiene purpose at a very affordable price. It is non-skin irritant and non-toxic as well as free from Type I Latex Allergy & Type IV Allergic.
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.
What is CPE pipe?
Chlorinated Polyethylene (CPE)
What is CPE bag?
CPE is chlorinated polyethylene, which is a polymer material made of high-density polyethylene (HDPE) through chlorination. CPE bag has good dispersibility, better anti-oxidation performance than ordinary plastic bags, very good toughness and soft hand feeling. The conventional CPE thickness in the market is 0.035mm.
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 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 increases the flexibility of a wire?
Most industrial wire is made up of multiple wire strands, called ‘base strands’, rather than being made of a solid piece of metal. Multiple strands make the wire more flexible, allowing it to bend and flex more easily than solid metal. The finer the base strand, the more flexible the wire.
What is EPR insulation?
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.
Are cable jackets waterproof?
It may be that when you read the title of this blog, “Waterblocking” that you thought to yourself, “Isn’t ALL jacketed wire and cable waterproof?” The answer is “No.” Almost every jacket compound, from PVC to Polyethylene to Teflon® is at least water resistant, so they can get wet and then dry out and they cables would
What material can be used for wire jacket?
Cable jackets are most frequently made out of poly(vinyl chloride), polyethylene, chlorinated polyethylene, and chlorosulfonated polyethylene/neoprene.
How do I know if my plastic is compostable?
Another way to tell is to look for the plastic recycling symbol. Compostable plastics fall into the catch-all category marked by the number 7. However, a compostable plastic will also have the letters PLA underneath the symbol.
Is HDPE a plastic?
But high-density polyethylene (or HDPE) plastic has been courting my favor recently. Not only is it one of the most versatile of plastics—used in everything from hard hats to house wraps—it’s also widely recycled, in both its rigid form (e.g., containers) and flexible form (e.g., bags).
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.
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.
