HDPE and LDPE are thermoplastics, so they can be. Any plastic that can be recycled are separated according to their resin type. This means that LDPE – classed under recycling number 4 – and HDPE – classed as recycling number 2 – are recycled separately. The process for recycling both plastics is the same, however.

HDPE has higher abrasion and tear resistance than LDPE, along with higher tensile and shear strength. If you're going to bury your cables underground, then opt for HDPE. Otherwise, LDPE is an excellent choice. LDPE cable conduits give you outstanding flexibility, a high fatigue life and high-impact strength.
Difference from LDPE: HDPE has a higher tensile strength and rigidity compared to LDPE. Toughness: HDPE is known for its toughness and resistance to impact, making it suitable for durable applications. Misconception: Despite its rigidity, HDPE is recyclable and environmentally friendly, contrary to the misconception that rigid plastics …
