SN-3M Series of Medium-temperature FoamingAgents

Product Introduction:

This series of foaming agents is used widely in the foaming ofsuch plastics as EVA, PE and PVC and multiple rubbers. Inparticular, it is suitable to the hot-pressing molding of EVA shoematerial 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 at160âÃÂÂÂ??ÃÂÂÂ??ÃÂÂÂ??ÃÂÂÂ??ÃÂÂÂ??ÃÂÂÂ??ÃÂÂÂ??ÃÂÂÂ??ÂÂÂÂ??ÃÂÂÂ??ÃÂÂÂ??ÃÂÂÂ??ÃÂÂÂ??ÃÂÂÂ??ÃÂÂÂ??ÃÂÂÂ??ÃÂÂÂ??ÂÂÂÂ??or so in EVA/rubber mixture to give rise to useful nitrogen, carbondioxide and a small amount of ammonia. The decomposing temperatureof medium-temperature foaming agent is not high, no activator isneeded to add for activating its decomposition, and it maydecompose completely within a short time length without producingthe unnecessary color resulting from the residual foaming agent. Ora small quantity of zinc oxide or stearates may be added to it toactivate it so that it may decompose at a lower temperature.

The decomposition of this series of foaming agent is mildrelatively, and the process of its decomposition matches thehalf-time of decomposition of bridging agent (DCP), so that thefoaming speed may match the bridging speed. All of those lead tothe following result: pores in the foamed products will becomefine, 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 foamingagents may endow products with an adequate whiteness without addingtoo much such white paint as titanium dioxide, which helps to avoidsuch a consequence, other physical performances of he product isaffected by adding too much white paint.

The series of foaming agents is free of the odor characteristicof formaldehyde generated by common low-temperature of foamingagents.

As an ideal improved AC foaming agent, the medium-temperaturefoaming agent integrates the merits of both high- andlow-temperature foaming agents together.

Package and Storage:

 

This series of foaming agent features excellent stability whenstored under the common temperature. It should be kept in the cooland dry place and be kept far from hot steam pipeline, fire source,and direct sunlight. Never let it contract direct acids andalkalis. It is suggested that good ventilation conditions should berealized where the foaming agent is treated or mixed. Be carefulnot to inhale its powder, not to make frequent skin contact with itand not to swallow it.

A bag contain 25kg of this kind of foaming agent, bags arepacked in cartons or barrels, depending on clientsâÂÂÂ??ÂÂÂ??demand.

The total weight of this foaming agent series in a batch amountto 3 Tons. While using the foaming agent of the same batch, usersmay test only a handful of it for /confirm/iation, if the test resultis ok, then they may use the whole batch with certainty.
