Analysis of heat stabilizers

 Heat stabilizers are an important class of plastic of processing aids, heat stabilizers of PVC resin, the  titanium dioxide birth and development simultaneously, mainly for the processing of PVC resin, heat stabilizer and so PVC resin, PVC products, the proportion of hard and soft close relationship. The current global annual consumption of about 500,000 tons, the main varieties of lead salts, organic tin, metal soaps, composite stabilizer and organic additives. Heat stabilizer consumption structure in different countries, in the United States, composite stabilizer total consumption 40% -50%, organic tin accounted for nearly 40%. Heat stabilizers, cadmium, low lead, dust-free, and instead of lead salts to become the  carbon black industry's development priorities. Demanding of environmental regulations is driving the change in heat stabilizers, in order to protect the human living environment, many countries have passed laws limiting toxic heavy metals in PVC processing application. European PVC heat stabilizers manufacturers have made a commitment that by 2010 the amount of heat stabilizers containing lead will be halved by 2015, the full realization of lead-free. Many European countries are using calcium-based or based on organic tin - zinc substitutes instead. The yellow iron oxide  amount of lead stabilizers in Europe in 1999 from 120,000 tons / year reduced to 2010 80,000 tons / year. Asia-Pacific region is expected to lead heat stabilizers demand will also be greatly reduced. Including those based on organic tin system (OBS), including new stabilizer has been widely used in the United States.
