Product Detailed Specifications
Appearance
Chemically cross-linked polyethylene (XLPE) compound pellets: Supplied as cylindrical or spherical, uniformly sized, free-flowing pellets with a smooth surface.
Color: Commonly available in creamy white or black (with carbon black added for enhanced UV resistance); other colors can be customized.
Odor: Odorless
Packaging: Typically in 25 kg moisture-proof polyethylene bags, with 500 kg or 1000 kg bulk bags available upon request.
Storage: Store in a cool, dry, well-ventilated area away from direct sunlight. Avoid contamination and high temperatures before processing.
This physical form ensures consistent extrusion performance during cable production, reduces material waste, and improves insulation uniformity.
