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.
