Mega’Zorbe Hydrophobic Melamine Foam (Without self-adhesive backing) is an enhanced version of melamine foam with exceptional water-resistance properties maintaining all other key attributes for sound deadening. Mega’Zorbe is extremely lightweight and flexible. The open cell surface allows sound waves to penetrate the foam and not reflect as an echo. Recommended for both acoustical and thermal insulation in aircraft, aerospace, marine, automotive, and architectural applications. Mega’Zorbe is resistant to most organic solvents and is an aerospace grade product.
Applications include ceilings, doors, trunk lids, etc. This product is not recommended for use in engine bays or near heat sources. Check out Mega’Block Hydrophobic Foam for high heat applications.
Mega’Zorbe is designed and manufactured in Germany with the proprietary hydrophobic process being completed in the USA. Mega'Zorbe melamine foam is eco-friendly, produced without using halogenated hydrocarbons and/or toxic heavy metal flame retardants. (*Nitrogen is used to create flame resistance). The products light weight characteristic reduces weight contributing to energy savings thus reducing emissions.
* Mega'Zorbe Standard does not include the PSA self adhesive backing. *
