(called Melamine Foam) made from
melamine resin. It is a kind of open-cell (over
99% open rate) thermosetting and eco-
friendly foam.
PAGE 01

Application temperature Up to 240
Stable physical and chemical performance from -150 to 200
Excellent thermal insulation
High sound absorption
Low-temperature flexibility
Light-weight (one of the lightest foam in the world)

4. Fire Resistance

02OTHERS
YarQuenXer, can meet the requirements of the following standards without any flame
retardant or additive, DIN4102, Class B1 low flammable material standard; UL94-V0 high
flame retardant material standard; Fireproofing authentication of BS 6853, NF F16-101 and
DIN5510; GB/T8624-2006, Class B (non-flammable) retardant flammable material
standard.
Excellent flame retardancy property is shown as below:
Prompt carbonization: When coming into contact with open flame, no flame is formed, no
drips, the surface of YarQuenXer carbonizes immediately, oxygen is isolated and reaction
speed slows down;
Stop burning immediately once open flame leaving: Once open flame leaves melamine
foam stops burning straight away, no spark;
Low density of smoke: Smoke is the main cause of human injury in fire disaster. Tests
show that the density of smoke of YarQuenXer is below 15, which is far lower than foam
material of same kind, e.g. the density of smoke of flame retardant PU foam is below 75
(GB/T8627-2007 Test Method for Density of Smoke from Burning or Decomposition of
Building Materials)

YarQuenXer has three-dimensional grid structure or open-cell and high open property (the
open rate of YarQuenXer is over 99% with density of 4-11kg/m3). Sound wave, therefore,
can go into the innermost of foam conveniently & effectively and be transformed to
vibration of grid, thereby being consumed and absorbed and eliminating reflected wave
effectively as well. It has good sound absorption performance in a wide audio range,
especially high & Middle-frequency noise.

6. Chemical resistance
Eco-friendly
PAGE 04
02OTHERS
YarQuenXer is resistant to all organic solvents, Thanks to its highly
cross-linked structure. When it comes to acids and alkalis, the
resistance has to be checked in actual application conditions since
the temperature, the exposure time and the concentration all have a
great deal of influence on the resistance of the foam to these media.
YarQuenXer is produced without using
halogenated hydrocarbons, flame retardants and
/or toxic heavy metals. YarQuenXer does not
contaminate water. The supplied product is free of
blowing agents and is not subject to labeling
requirements under the China hazardous material
regulations.
Solutions with YarQuenXer reduce the weight of
the components, thus contributing to energy
savings and to a reduction in emissions in
transportation applications. The excellent cleaning
effect is achieved without the need for any other
chemical cleaning agents.
Thanks to the product’s property profile,
YarQuenXer contributes to efficient energy
utilization and to improving the well-being of
people in buildings and vehicles.

APPLICATIONS
PAGE 08
High-speed rail and metro are spreading
worldwide. The transportation field has
huge demand and high requirement for
both sound absorption and thermal
insulation material, but light-weight
material. YarQuenXer provides high sound
absorption performance, excellent thermal
insulation, fire-resistance performance, but
light-weight, therefore, YarQuenXer is the
most ideal material for transportation
applications.
Transportation
Noise is mainly from the vibration of motor, the friction between wheels and the ground,
whistling sound of air, resonance of automobile body, etc. To eliminate noise, sound
absorption material is used to separate and absorb noise as main measure except design.
New energy automobile will be favored more and more. YarQuenXer provides high sound
absorption performance, excellent thermal insulation, fire-resistance performance, but
light-weight, therefore, YarQuenXer is the most ideal material for transportation
applications. It can provide important support to noise reducing, comport increasing and
level rising.

energy-saving and safety. Especially in
high-speed rail and narrow-gage train, the
comprehensive properties such as light-
weight, flame retardancy and environmental
protection, and sound absorption, etc. can
be exerted even more sufficiently.
The advantages of comprehensive properties of YarQuenXer enable it to be used in
aviation, military industry, etc. to play the roles in safety, energy-saving, sound pressure
reducing, audio frequency receiving and screening. YarQuenXer can be used as seat or
filling to reduce the self-weight of vehicle, increase performance and reduce energy
consumption.

Besides high sound absorption performance and excellent thermal insulation performance,
YarQuenXer, as cleaning supplies, thanks to its Abrasiveness property, are popular by
clients.
YarQuenXer has strong soft abrasiveness and
adsorption of obstinate stain and dust. Meanwhile, it
has hydrophilicity and lipophilicity. Obstinate stain
can be removed by YarQuenXer with water rather
than any detergent without damaging the surface.
YarQuenXer adhered stain will become clean again
after washing by water. Using YarQuenXer as
cleaner is convenient and easy, toxic side effect of
chemical detergent is avoided. YarQuenXer is
natural enemy of obstinate stain. It is a good
assistant of family, restaurant and hotel.
YarQuenXer can be used in thermal insulation for piping of industry and household, thermal
insulation and noise reduction for air-conditioning and ventilation system. It can be made to
soft wall board and wall-insulation board, etc. YarQuenXer overcomes the disadvantage of
other products such as flammability and powering. YarQuenXer is our severe safety guard
