FAQs
What does LLDPE stand for, and why is it used in rotomoulding?
LLDPE (Linear Low-Density Polyethylene) is a thermoplastic polymer used in rotomoulding due to its high flexibility, impact resistance, and excellent durability.
Linear molecular structure: Provides improved toughness compared to conventional LDPE (Low-Density Polyethylene).
High elongation properties: Ensures flexibility in moulded parts.
Superior stress crack resistance: Ideal for tanks, containers, and industrial products.
What are the main raw materials used in manufacturing LLDPE rotomoulding powder?
Ethylene (C₂H₄) – The primary building block.
Alpha-olefins (e.g., butene, hexene, octene) – Improve polymer flexibility and strength.
Catalysts (Ziegler-Natta or Metallocene Catalysts) – Control polymerization for better material properties.
What is the particle size distribution of LLDPE rotomoulding powder, and why is it important?
Standard size: 200-500 microns (µm).
Importance:
Smaller particles (<300 µm) → Faster melting, smoother finish.
Larger particles (>400 µm) → Uneven melting, rough texture.
Consistent size ensures uniform wall thickness in moulded products.
What is the specific gravity of LLDPE, and how does it affect product weight?
Specific Gravity (SG): 0.915 – 0.940 g/cm³ (ASTM D792).
Impact on weight:
Lower SG → Lighter products, ideal for transport applications.
Higher SG → Denser, stronger products, used for structural applications.
What is the typical Melt Flow Index (MFI) of LLDPE rotomoulding powder?
Melt Flow Index (MFI) measures polymer flow rate at 190°C under a 2.16 kg load (ASTM D1238).
Standard range: 3-7 g/10 min.
Higher MFI → Faster flow, thinner walls.
Lower MFI → Higher viscosity, stronger walls.
What is the Vicat Softening Temperature (VST) of LLDPE?
Vicat Softening Temperature (VST) determines when the polymer begins to soften under heat (ASTM D1525).
Range: 85-110°C.
Higher VST → Better high-temperature performance.
What is the Heat Deflection Temperature (HDT) of LLDPE, and why is it important?

LLDPE HDT: 40-60°C.
Importance:
Ensures shape retention under heat.
Prevents warping in outdoor applications.
How does LLDPE resist impact forces, and what is its Izod Impact Strength?
Izod Impact Strength (ASTM D256): 50-150 J/m.
Higher values indicate better resistance to cracks and mechanical shocks.
Ideal for water tanks, automotive parts, and industrial containers.
What is the Tensile Strength of LLDPE, and why is it important?
Tensile Strength (ASTM D638): 10-25 MPa (Megapascals).
Importance:
Determines ability to withstand stretching forces.
Stronger LLDPE → More durable, long-lasting products.
What is the Environmental Stress Crack Resistance (ESCR) of LLDPE?
ESCR (ASTM D1693): Measures polymer resistance to cracking under chemical exposure.
LLDPE ESCR is high, making it suitable for chemical storage tanks and industrial applications.
How does LLDPE perform in UV exposure, and what are UV stabilizers?
UV resistance (ASTM G154): LLDPE requires UV stabilizers to prevent degradation.
UV stabilizers: Hindered Amine Light Stabilizers (HALS) and Carbon Black.
Without UV stabilizers: Cracking, brittleness, and color fading occur over time.
What is the Coefficient of Linear Thermal Expansion (CLTE) of LLDPE?
CLTE (ASTM D696): 150-200 x 10⁻⁶ mm/m°C.
Impact:
Higher CLTE → More expansion in heat, risk of warping.
Lower CLTE → More dimensional stability.
What is the abrasion resistance of LLDPE, and how is it tested?
