Mega'Zorbe Standard Hydrophobic Melamine 1/2" Foam No Adhesive Backing - 1 Sheet (24"x 48" = 8 sqft)

Calculated at checkout

Product Description

Mega’Zorbe Standard Hydrophobic Melamine Foam is an enhanced version of melamine foam, which gives exceptional water-resistance properties, which is not achievable with standard melamine foam, while maintaining all other key attributes that are valuable for us in the sound deadening industry. Mega’Zorbe Hydrophobic Melamine foam is an extremely lightweight and flexible material which exhibits exceptional resistance to heat and water, low flame propagation and smoke generation, and toxicity. Mega'Zorbe's open cell surface allow sound waves to penetrate the foam and not reflect the waves as an echo. Mega’Zorbe is differentiated from traditional melamine and polyimide foams by its resistance to moisture absorption and retention, produced by a proprietary process. As with standard melamine foam, it does not drip in the presence of a flame and stops burning after removal of any external ignition source and fuel. It is recommended for both acoustical and thermal insulation in aircraft, aerospace, marine, automotive, and architectural applications where extreme moisture resistance, low flame spread, smoke generation and toxicity are requirements. Mega'Zorbe's foam is resistant to all organic solvents. Mega'Zorbe meets the most important national and international fire safety standards, the products long term resistance to high temperatures and excellent fire characteristics come from the high quality melamine resin used to manufacture the product. 

*** This Mega Zorbe does not include the PSA self adhesive backing. It will require some sort of glue or tape to adhere to your project ***

Each sheet of Mega’Zorbe Hydrophobic Melamine Foam is 24" x 48" x 1/2" for a total of 8 sqft of coverage

Mega’Zorbe’s melamine foam is not produced in America like the rest of Second Skins products are, but it is designed and manufactured by a very reputable and high quality manufacturer in Germany and the hydrophobic process is applied here in the great United States of America. Mega'Zorbe melamine foam is eco-friendly too, it is produced without using halogenated hydrocarbons, flame retardants (*nitrogen used to create flame resistance) and/or toxic heavy metals. It also reduces the weight of vehicle builds, in turn contributing to energy savings and reduction in emissions in vehicle applications. 

Applications for this melamine foam include ceilings, doors, trunk lids, and any upside down surface that our mass loaded vinyl Luxury Liner Pro is too heavy to be applied (product should not be used in engine bays or near heat sources, we offer this product with a heat shield on it for those applications)
