Rotomoulding Granules

Product Description

Rotomoulding granules are plastic raw materials used in rotational moulding (rotomolding) to make hollow, stress-free products like water tanks, bins, kayaks, toys, and containers.

Key points

• Most common material: LLDPE (Linear Low-Density Polyethylene)
  Other options: HDPE, LDPE, PP, XLPE, Nylon (for special applications)

• Form: Usually supplied as powder, but granules are melt-ground into powder before processing or used in newer direct-granule systems.

• Properties needed:

  • Good flow and melt strength

  • Thermal stability (long heating cycles)

  • Impact resistance

  • UV stabilization (for outdoor products)

• Typical additives:

  • UV stabilizers

  • Color masterbatch

  • Antioxidants

  • Foaming agents (for double-wall products)

Common applications

• Water & chemical storage tanks

• Road barriers & dustbins

• Agricultural tanks & crates

• Furniture & playground equipment

Advantages

• Uniform wall thickness

• No high pressure low internal stress

• Ability to mould complex hollow shapes
