80 years Beijing Plastics Research Institute established the AC blowing agent as a PVC artificial leather PVC foam blowing agents and stabilizers act as a reasonable choice of the activation of AC blowing agent additive basic theory, has guided the production of artificial leather PVC foam. Although the PVC leather surface treatment methods and patterns are constantly changing, but more than 20 years, PVC foam leather foam foam hole quality, the rate of inadequate or unstable PVC synthetic leather has been plagued by development of the industry, coupled with people's awareness of environmental protection in recent years enhanced the public on the traditional PVC stabilizer is very concerned about the heavy metals. The European Commission clearly stated since 2006, the European market, PVC products can not contain heavy metals, to use environmentally friendly type of stabilizer. Although there is no right of our country PVC artificial leather in the heavy metal stabilizing agent used to restrict the request, but in some big cities (such as: Beijing, Shanghai, etc.) have been of some use pipes, profiles to restrict the request, clearly can not be used contain lead pipes, Sheung Shui, salt PVC plastic pipe. PVC artificial leather is widely used in each of China has a large number of PVC artificial leather exports to the EU and other developed countries. Production of PVC foam leather rolling type of business-to-the demand for environmentally friendly stabilizers are also getting bigger and bigger.
    Is now recognized as the world's non-toxic formula can be used for PVC heat stabilizers, mainly of organic tin and composite calcium / zinc type. We are talking about here, the environmental stability of agents whose main ingredient, compared with Ca, Mg, Zn, K, Al and so on. Such stabilizing agent in the country, many companies are in production and R & D, but how to incorporate environmental protection and foam stabilizer combination of better applied to leather foaming them to, and improve product quality, reduce production costs. This production enterprises in China can be said to be a blank. In recent years, our company researchers SONG and strong after many years of efforts, through the National Plastics Center, Beijing University of Chemical Technology and other units of the experts, joint research, for the rolling technique PVC foam leather production process, developed the environmentally friendly PVC artificial leather made foam stabilizer, a national patent applications to fill the gaps in the domestic.

    Environment-friendly PVC leather foam stabilizer mechanism

    In general, PVC foam and melt the following factors:

    1, and the temperature, blowing agent decomposition temperature of high gas greater.

    2, and AC Stabilizer activation in right AC are the amount of ingredients.

    3, and the melt viscosity of the PVC, and AC breakdow
