Noise foam , also known as sound
insulation materials, noise sponge, Shanghai Zhong Tian rubber and
plastic
production of sound insulation foam with high performance EVA, PE, PU or
EPDM as the main raw material, with the
All kinds of high-quality accessories, the high-temperature mixed foam
made of noise foam material. Sound
insulation / sound-absorbing foam is mainly divided into PU sponge, PE
foam, EVA foam, EPDM rubber foam
materials. Product environmental non-toxic, practical and durable,
exquisite workmanship. Second, the following
is one of several noise foam-related presentations: 1, EVA foam: EVA
rubber products is a new type of
environmentally friendly plastic foam material, has a good cushion,
shock, heat, moisture, chemical corrosion,
And non-toxic, non-absorbent. EVA rubber and plastic products can be
processed by the design, the shock
performance is better than polystyrene (foam) and other traditional foam
materials, and in line with
environmental requirements, is the best choice for export products.
Relative to the shock packaging can be cut,
forming; due to large differences in density, can also have a wider
range of uses. Such as automobiles, air
conditioners, refrigerators, freezers, household appliances, engineering
refrigeration and refrigeration and
refrigeration, etc .; skates, sports shoes lining materials, sports
insoles, bags back pad, surfboards, kneeling
pads. 2, PE foam: low density foam PE: bulk density is small, with good
insulation, waterproof, cushioning
performance. High density foam PE: high physical strength, good oil
resistance, solvent resistance, aging
resistance. Uses: low-density foam PE is mainly used for the
construction industry insulation / insulation; for
life jacket core materials, air conditioning and refrigeration
accessories, machinery and equipment seals buffer
pieces, heat-setting pieces, all kinds of precision instruments, medical
tools, measuring packaging Lining and so
on. High-density foam PE for shoe materials, pressure pieces, seals and
other pieces of damping. PU foam: PU foam
also known as PU sponge, PU foam, polyurethane sponge, sponge, etc.),
the product is foam resin, foam additives
and adhesive resin (so that the product has adhesion ), And then foaming
them. The raw materials such as ethylene
vinyl acetate (EVA) are mixed together, foamed in the mold, and the
obturator is crushed by mechanical force to
obtain the foamed sponge. Depending on the size of the internal bubble,
various densities can be exhibited and
various shapes can be produced by molding in accordance with need. PU
foam is widely used in electrical
appliances, craft gifts, glass ceramics, building waterproof, travel
bags, daily necessities, product packaging
and so on. It relates to automobile industry, battery industry,
cosmetics industry and high-grade furniture.
Manufacturing and other industries. This product has the characteristics
of sound insulation, fireproof, high
temperature resistance, cold resistance, cushioning, shock absorption,
water resistance, corrosion resistance,
hydrochloric acid resistance and long service life. Sound insulation
foam is widely used: the purpose of noise is
cut off unnecessary external sound source, so as not to interfere.
Therefore, the noise insulation foam is widely
used in automobile, train, subway, airplane, ship, air conditioner,
chemical industry, instrument, electrical
appliance, building, floor, wall, window and so on.
