Xlpe black granola manufacturer in china
Cross-linked polyethylene, which is trademark xlpe , XLPE insulated cables are ideal for transmitting higher voltage without hindrance or compromise to its effectiveness. Thanks to their remarkable insulation properties, XLPE insulated cables surpass other alternative insulation materials like Silicon rubbers, and even Ethylene Propylene Rubber, EPR.
The list of xlpe applications is endless and every industry where it’s been utilized takes advantage of one or more of its unique properties. In mines, for instance, it’s the ability to withstand extremely high pressure and temperature and still maintain its toughness that makes it a suitable material.
China, one of the leading industries in the field of production of power cables and composite materials, has a significant need for xlpe black and xlpe natural for the market and industry.
Pitaris the manufacturer xlpe granolasin the Middle East is trying to supply the market and establish a network with traders.
Xlpe black granola for wire company
Compared to ordinary polyethylene, cross-linked polyethylene xlpe black granola has enhanced properties that give it an added advantage in performance.
xlpe black wire with its improved properties doesn’t melt easily and can withstand higher temperatures of up to 120°C for an extended time without losing its mechanical and chemical properties. The young modulus is also increased as well as its resistance to abrasion and environmental stress. The cross-link of the polymer structure changes the thermoplastic into a thermoset, hence the resultant improvement in xlpe properties as discussed.
Cross-linking xlpe insulation cables can best be described as vulcanizing the rubber with the addition of littles amounts of chemical additives to help rearrange the molecular structure into a lattice that hinders the movement of molecules in the presence of heat.
Hence, xlpe black granules have been replaced pvc in cable factories and have become the primary cases of making black cables.

Low-temperature impact strength, abrasion resistance and environmental stress cracking resistance can be increased significantly by crosslinking, whereas hardness and rigidity are somewhat reduced. PEX does not melt any more (analogous to elastomers) and is thermally resistant (over longer periods of up to 120 °C, for short periods without electrical or mechanical load up to 250 °C). With increasing crosslinking density also the maximum shear modulus increases (even at higher temperatures). PEX has significantly enhanced properties compared with ordinary PE. Crosslinking enhances the temperature properties of the base polymer. Adequate strength to 120–150 °C is maintained and chemical stability enhanced by resisting dissolution.
A theoretically extreme degree of cross-linking is reached if only –CH2– bridges are placed between cross-linkings that are also –CH2– bridges and if the polymer structure’s sum formula is (C3H4)n, then the structure is that of a diamond with all bonds replaced by –CH2– bridges. If 4 vertices of a cube c are placed where C-atoms of the diamond base are so that only one further diamond base atom lies inside c then 4 diamond base bonds lie in c and—because the bond angles are forced towards such maximal values that also here a diamond cubic crystal structure is already approached—it is expected that the C-atoms of these –CH2– bridges are posed on lines that are both orthogonal to diamond base bonds and parallel to faces of c.
Almost all cross-linkable polyethylene compounds (XLPE) for wire and cable applications are based on LDPE. XLPE-insulated cables have a rated maximum conductor temperature of 90 °C and an emergency rating up to 140 °C, depending on the standard used. They have a conductor short-circuit rating of 250 °C. XLPE has excellent dielectric properties, making it useful for medium voltage—1 to 69 kV AC, and high-voltage cables—up to 380 kV AC-voltage, and several hundred kV DC.
