SN*3M
Series of Medium-temperature Foaming Agents
Product Introduction:
This
series of foaming agents is used widely in the foaming of such
plastics as EVA, PE and PVC and multiple rubbers. In particular, it
is suitable to the hot-pressing molding of EVA shoe material in
large or small molds.
Characteristics:
Foaming at medium
temperature,
High Whiteness of
products,
Stable foaming
ratio,
Uniform and fine pore
holes,
No formaldehyde,
Safe and
environment-friendly.
Application Specification:
This
series of foaming agents may decompose at **0℃ or so in
EVA/rubber mixture to give rise to useful nitrogen, carbon dioxide
and a small amount of ammonia. The decomposing temperature of
medium-temperature foaming agent is not high, no activator is
needed to add for activating its decomposition, and it may
decompose completely within a short time length without producing
the unnecessary color resulting from the residual foaming agent. Or
a small quantity of zinc oxide or stearates may be added to it to
activate it so that it may decompose at a lower
temperature.
The
decomposition of this series of foaming agent is mild relatively,
and the process of its decomposition matches the half-time of
decomposition of bridging agent (DCP), so that the foaming speed
may match the bridging speed. All of those lead to the following
result: pores in the foamed products will become fine, the time
necessary for foaming and bridging will be reduced, the performance
of the foamed product will become excellent, and , in particular,
the rebound elasticity will be enhanced greatly.
Like low-temperature foaming
agents, this series of foaming agents may endow products with an
adequate whiteness without adding too much such white paint as
titanium dioxide, which helps to avoid such a consequence, other
physical performances of he product is affected by adding too much
white paint.
The
series of foaming agents is free of the odor characteristic of
formaldehyde generated by common low-temperature of foaming
agents.
As an ideal improved AC foaming
agent, the medium-temperature foaming agent integrates the merits
of both high- and low-temperature foaming agents
together.

Package and Storage:
This
series of foaming agent features excellent stability when stored
under the common temperature. It should be kept in the cool and dry
place and be kept far from hot steam pipeline, fire source, and
direct sunlight. Never let it contract direct acids and alkalis. It
is suggested that good ventilation conditions should be realized
where the foaming agent is treated or mixed. Be careful not to
inhale its powder, not to make frequent skin contact with it and
not to swallow it.
A bag
contain *5kg of this kind of foaming agent, bags are packed in
cartons or barrels, depending on clients’ demand.
The total weight of this foaming
agent series in a batch amount to 3 Tons. While using the foaming
agent of the same batch, users may test only a handful of it for
confirmation, if the test result is ok, then they may use the whole
batch with certainty.
