🔹 Plasticman (South Africa)
-
Sizes available: 15 mm, 20 mm, 25 mm, 32 mm, 40 mm, 50 mm, 65 mm (100 m rolls), and 80 mm (50 m roll)
-
Typical packaging: 100 m coils, weight ~7–9 kg, dimensions ~90 × 90 × 13 cm
-
Intended use: Ideal for low-pressure irrigation, class 6 rating for pressure suitability.
Material Description – LDPE Properties
-
Thermoplastic made from ethylene, first produced in 1933
-
Density: 917–930 kg/m³, naturally flexible and tough, but lower stiffness than HDPE—suitable for irrigation
-
Recommended for: Low-pressure irrigation; Class 6 indicates ~600 kPa rating under standard conditions.
-
Resistance profile:
-
Excellent: acids, bases, alcohols, esters
-
Good: aldehydes, ketones, oils
-
Limited: hydrocarbons, mineral oils
-
Poor: halogenated hydrocarbons
-
🛠 Class 6: Intended Usage & Fitment
-
Irrigation use only: Not for potable water or exposed potable installations; use LDPE Class 6 in subsurface or garden systems only .
-
Fitting type: Designed for swaged insert fittings (compressed into ID), secured with hose clamps. Swaging reduces ID, so usually upsizing fittings is needed—or use “full-flow” style
-
Fitting compatibility: Works with standard LDPE push-fit or insert fittings (not compression-style like HDPE)
