Mega'Block Hydrophobic Melamine 1/2" Foam - 1 Strip (24"x12"= 2 sqft)

Calculated at checkout

Product Description

Mega’Block Hydrophobic Melamine Heat Shield is an aluminum foil-faced fiberglass fabric composite on top of our Mega’Zorbe hydrophobic melamine foam designed to reflect radiant heat while offering excellent sound absorbing attributes with protection to high heat exposure with an easy peel and stick application. Mega’Block hydrophobic melamine heat shield 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’Block 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’Block 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’Block’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. Applications for this thermal insulation include hoods, firewalls, above gas tanks and any other areas exposed to extreme heat from exhaust pipes, turbos, etc (product must be kept 2” from any heat source and foil tape should be used on the edges to protect the foam)

  • Extremely thin heat shield (0.035") and lightweight (2.3 oz/ft²) on 1/2" Hydrophobic Melamine Foam
  • Easy Peel and Stick application with high heat adhesive 
  • Temperature up to 1000°F in localized areas within a larger area of material
  • Highly polished foil reflects 98% of radiant energy
  • Extremely durable. lightweight and flexible

 Each sheet of Mega’Block Hydrophobic Melamine Heat Shield Strip is 24" x 12" x 1/2" for a total of 2 sqft of coverage

MegaBlock needs to be 1" away from any heat source.

Typical Places of Use (We recommend taping seams and edges with high temp foil tape when using close to heat sources):

  • Engine Side Firewall - Reflect up to 1,000 degrees F away from cabin.
  • Hood - On top of a vibration damper to deflect heat from engine away from a hood to protect paint job.
  • ATV/Jet Ski/Snowmobile - Under the seat or above the engine which usually is below the rider. It deflects the heat away from the rider.
  • Back Seat Wall - For rear engine vehicles, to keep heat from coming through back seat area.
