HDPE (High-Density Polyethylene)—commonly referred to as HDPE plastic—is a versatile thermoplastic known for its excellent strength-to-density ratio, chemical resistance, and durability. At Northeast Plastics, we offer HDPE sheets and HDPE rods suitable for various industries, including food processing, marine, and construction. Whether you’re exploring marine grade HDPE for boat components or HDPE cutting board material for a hygienic, food-safe surface, this high-performance material stands out for its adaptability and cost-effectiveness.
Technical Info
- Material Name: High-Density Polyethylene (HDPE)
- Density: ~0.94–0.96 g/cm³ (lower density than metals, making it lighter and easier to handle)
- Temperature Range: Typically handles -100°F to 180°F (-73°C to 82°C)
- Tensile Strength: ~4,000 psi (varies by grade)
- Chemical Resistance: Excellent against most solvents, acids, and bases
- FDA Compliance: Many HDPE grades are approved for food contact; always verify certifications with the supplier
BEnefits
High Strength-to-Weight Ratio
Delivers solid structural support without adding unnecessary bulk, ideal for lightweight yet sturdy applications.
Chemical & Moisture Resistance
Resists most chemicals and repels moisture, making HDPE sheets a prime choice for harsh or wet environments.
Temperature Resilience
Performs well in a broad range of temperatures, ensuring stability for outdoor or cold-room applications.
Food Safe Options
Many HDPE plastic grades are FDA-approved, suitable for direct food contact in cutting boards or food storage equipment.
Applications
Cutting Boards & Food Processing
HDPE cutting board material provides a hygienic, easily sanitized surface for industrial kitchens and home use.
Marine Parts & Dock Components
Marine grade HDPE endures constant exposure to water, sunlight, and salt air without warping or degrading.
Chemical Tanks & Piping
Excellent chemical resistance makes high-density polyethylene tanks suitable for storing corrosive liquids.
Construction & Signage
Ideal for panels, protective barriers, and UV-stabilized outdoor signs due to its weather-resistant properties.
Playground Equipment
Lightweight yet tough, HDPE stands up to frequent use while minimizing maintenance.
Industrial Linings & Wear Parts
HDPE sheets and HDPE rods are machinable for chutes, liners, or other high-wear areas where impact resistance is key.
FAQ
ask us
anything
Is HDPE Food Safe?
Yes. Many HDPE plastic formulations meet FDA requirements for direct contact with food, making them popular in cutting boards and food processing equipment.
How Does HDPE Compare to UHMW?
HDPE vs. UHMW mainly differs in molecular weight. UHMW generally offers superior abrasion resistance, while HDPE provides an economical solution with good strength, chemical resistance, and ease of machining.
Can HDPE Be Used Outdoors?
Absolutely. High-Density Polyethylene is often UV-stabilized, making it suitable for outdoor applications like marine dock parts, playground equipment, and signs.
What Tools Are Best for Cutting HDPE Sheets?
Standard woodworking tools like circular saws or jigsaws with fine-tooth blades work well. To minimize melting, use moderate cutting speeds and support the sheet securely.
