MPP Foam Panel

MPP Foam Panel

Micro-foamed polypropylene insulation panel using supercritical CO2 technology. Suitable for food contact.

Applications
Refrigerated truck bodies, cold-chain logistics and insulated containers

XPS Foam Panel

XPS Foam Panel

Extruded polystyrene foam sandwich panel with high thermal insulation and compressive strength.

Applications
Cold storage walls, refrigerated vehicle bodies and building insulation

Structure and material

MPP (Micro-foamed Polypropylene) uses supercritical CO₂ technology to create a closed-cell foam structure without chemical blowing agents. The result is a food-safe, lightweight insulation material with thermal performance comparable to polyurethane foam.

Unlike PU foam, MPP panels do not absorb moisture or degrade over time. They maintain insulation efficiency throughout the vehicle's service life and are 100% recyclable at end of life.

Questions before ordering

What temperature range can MPP panels maintain?

MPP insulated bodies are designed for cold chain operations from -20°C to +8°C. Temperature maintenance depends on refrigeration unit selection, which we can help specify.

What makes MPP different from polyurethane foam?

MPP uses supercritical CO₂ to create closed-cell foam without chemical blowing agents. It is food-safe, fully recyclable, lighter than PU foam, and does not absorb moisture or degrade over time.

Is MPP food-safe?

Yes. MPP panels are food-safe for direct contact with food products, suitable for fresh produce, dairy, meat, and pharmaceutical cold chain transport.
