Melamine foam heat insulation material Introduction:
Melamine foam is a foam plastic commonly used for thermal insulation in the construction sector. It is a fluffy and lightweight material with good thermal insulation and flame retardant properties, so it is a common application in buildings for thermal insulation and insulation. The material can be used to infill structures such as walls, roofs and floors to reduce heat transfer and improve a building's energy efficiency.

Applicaction:
Industry
Gas pipes, air ducts, water heaters, reactors, air conditioners, workshops, etc., thermal insulation, sound absorption, and shock absorption
Transportation
Automotive engine insulation foam, hood silencer foam, transmission sound insulation pad, instrument panel retaining wall, insulation foam, high-speed rail roof insulation foam, power/energy storage battery insulation, buffering, and rubber blocking.
Architecture
It is widely used in noise reduction and sound absorption in sports venues, rail transit station waiting halls, airport terminal waiting halls, theaters, cinemas, libraries and other crowd gathering places.
New energy vehicles
Packaging using a polyethylene film bag. Specific packaging requires the two agreement.
Storage
1. Products should be stacked in clean, dry and warehouse according to different specifications, and should not be stacked in the open air to prevent exposure and not with corrosion Products, flammable products and other chemicals are stored together, and stacked level off.
2, Since melamine foam is a kind of foam with an opening rate of more than 99%,It is susceptible to the change of air temperature and humidity conditions and affect the adhesive performance, so it is recommended to store the temperature above 15ºC and the humidity below 60% In the environment.
3. At the same time, the storage and use conditions of the tape should also meet the requirements of the tape manual, such as the temperature of 15ºC Upper, the pressure is 1kg / cm ², and the pressure retention time is more than 5 seconds, so as to firmly bond with MF.
Q1.Can your company customize products?
A: Yes, We usually discuss with customers and help them find solutions.
