HDPE (High-Density Polyethylene) sheets are durable, versatile plastic materials known for their high strength-to-density ratio, chemical resistance, and weatherability. They are manufactured primarily through extrusion or compression moulding into various forms and dimensions for a wide range of industrial and commercial applications.
Density: Generally ranges from 0.94 to 0.97 g/cm³
Thickness: Available in a wide range, from as thin as 0.2 mm up to 35 mm or more, often specified in mils for geomembrane applications (e.g., 30, 40, 60, 80, or 100 mil).
Surface Finishes: Available with smooth, textured (e.g., for cutting boards or anti-skid surfaces), or T-ribbed (for enhanced friction and stability in lining applications) surfaces.
Color: Commonly available in black, white, blue, and various other multi-colors, with UV-stabilized grades available for outdoor use.
Chemical Resistance: Highly resistant to many acids, alkalis, solvents, and other corrosive substances, making them suitable for harsh environments.
UV Stability: UV-stabilized grades are available for outdoor applications, ensuring they can withstand prolonged exposure to sunlight without degradation.
SPARCO- HDPE sheets are used across numerous industries due to their versatility and durability:
Construction & Infrastructure: Used as damp-proof membranes, foundation waterproofing barriers, and protective liners for retaining walls.
Environmental & Waste Management: Essential for geomembrane liners in sanitary landfills, containment ponds, reservoirs, and water management systems to prevent the contamination of soil and groundwater.
Industrial: Utilized for fabricating chemical storage tanks, acid tanks, industrial floor lining, and specialized equipment due to their chemical resistance.
Food Handling: Matte and smooth HDPE sheets are FDA and NSF approved, making them ideal for cutting boards and hygienic food preparation surfaces as they do not harbour bacteria.
Agriculture: Employed for lining irrigation ponds and manure pits. Other Uses: Include snowboards, outdoor furniture, playground equipment, packaging materials, and orthotic/prosthetic devices.
