Base Material: LLDPE – Linear Low Density Polyethylene

LLDPE is the most widely used polymer worldwide for rotational molding (roto molding) tanks.
It is produced by copolymerizing ethylene with small amounts of α-olefins (such as 1-butene or 1-hexene).
Its molecular structure is linear with short-chain branching, which provides:
Higher flexibility.
Excellent resistance to environmental stress cracking (ESC).
Superior processability in roto molding compared to LDPE or HDPE

Key Properties of LLDPE for Roto molding

Density: 0.918 – 0.935 g/cm³
Melt Flow Index (MFI): 3–8 g/10 min (optimized for roto molding)
Melting Point: ~120–125 °C
Thermal resistance: Up to 60 °C continuous, 80 °C short-term
Chemical resistance: Excellent against diluted acids, bases, alcohols, and saline water
UV stabilization: With UV additives, service life can exceed 10–15 years in hot climates

Advantages of LLDPE Rotomolded Tanks

✅ Seamless construction → no leakage points
✅ High impact resistance → withstands shocks better
✅ Superior corrosion and chemical resistance
✅ Lightweight and easy to transport/handle
✅ Can be manufactured in very large capacities (up to ~50,000 L)
✅ Multi-layer options available:

Outer colored layer for UV protection
Inner black layer to prevent algae growth
Additional functional barrier layers if required
