Rotofoam

About Rotofoam

ROTOFOAM RFM 10 is a high-performance foaming agent masterbatch designed to create fine, uniform microcellular foam structures within polymer products, achieving significant weight reduction while maintaining excellent strength, rigidity, and surface quality. This advanced formulation contains carefully selected additives that release gases through controlled thermal decomposition, ensuring a uniform closed-cell structure and superior foam distribution. Based on endothermic foaming chemistry, it absorbs heat during gas release, improving processing stability, reducing scorch risk, and minimising impact on processing equipment.

The base polymer is polyolefin, ensuring excellent compatibility with a wide range of rotational moulding grades. Its optimised formulation provides consistent density reduction, enhanced thermal insulation, and excellent impact resistance, making it ideal for demanding applications such as large water storage tanks, insulated containers, and other hollow moulded products where lightweight performance and insulation are essential.

Multi-Layer Structure

Outer (First) Layer

White colour polyethylene (UV-stabilised) for weather resistance.

Second Layer

Black coloured polyethylene for added durability and aesthetic appeal.

Third Layer

Polyolefin foam layer for thermal insulation and rigidity.

Inner (Fourth) Layer

White polyethylene layer containing antifungal/antibacterial masterbatch for enhanced hygiene.

Benefits of Rotofoam

  • Substantial Weight Reduction – Cuts material and transport costs while maintaining exceptional durability and performance.
  • Optimized Strength-to-Weight Ratio – Delivers high mechanical strength even at reduced densities for maximum efficiency.
  • Superior Thermal Insulation – Closed-cell foam core significantly reduces heat transfer, improving energy efficiency.
  • High Impact Resistance – Absorbs shocks and withstands handling, transport, and environmental stress without damage.
  • Advanced Hygiene Protection – Antibacterial and antifungal inner layer ensures safe storage for water, food, and sensitive materials.
  • Excellent Corrosion & Chemical Resistance – Protects against moisture, chemicals, and harsh environments for extended service life.
  • Waterproof & Moisture Barrier – Prevents water ingress to safeguard internal contents and preserve structure.
  • Long-Term Durability – Resistant to cracking, warping, or degradation over prolonged use and extreme conditions.
  • Easy Processing & Manufacturing – Adaptable to various moulding and shaping processes for seamless integration.
  • Eco-Friendly Advantage – Supports sustainability through reduced raw material usage and recyclability potential.
