From the beginning of twentieth Century 80 years, countries around the world have proposed to prohibit the use of lead salt stabilizer, cadmium salts requirements:
A, Europe
a ,European Standardization Committee approved EN71-3 standard in March 11, 2000, restrictions on soluble eight heavy metals, including lead limit was 90mg/kg;
b ,The European Parliament and in 2000 passed the environmental bill 76/769/EEC-PVC material requirements of environmental protection green book, starting from August 2003, in electrical materials banned the use of lead salt and other 18 kinds of harmful substances, in 2015 to prohibit the use of lead salt stabilizer;
c ,The European Union in January 27, 2003 promulgated the "restrictions on the use of certain hazardous substances in electrical and electronic equipment" (RoHS), clearly defined,From July 1, 2006 onwards, all in the EU market of large, small household appliances, IT and remote equipment, communications equipment, audio visual equipment, lighting equipment, electrical and electrical tools, toys and leisure and sports equipment, vending machines, eight kinds of electromechanical products shall not contain lead, mercury, cadmium, hexavalent chromium, PBB six, PBDE six, etc. hazardous substances;
d ,In 2005 July 6, the European Parliament and the Board issued "on the development of energy consuming product design requirements for environmental protection framework directive 2005/32/EC" (EuP), which in order to improve the overall environmental performance of products, to ensure the security of energy supply, the directive covers all can use products. The production of China's plastics industry impact will be compared to RoHS and REACH regulations more serious;
e ,In 2006 22 months 28 days of the European Parliament and the Council of the European Union and put forward "on chemicals registration, evaluation, authorization and restriction system" regulations, namely REACH regulations, and come into effect in June 1, 2007, the lead limit of standard 1000mg/kg.
B,The other two, American, Canada and other countries
a , America Consumer Product Safety Commission in 1996 issued the No. 95-150 and No. 4426th document, the provisions from the 1996 of September, USA only allowed PVC products lead content is less than 200 × 10-6 into the market.
b , Canada, South America, some countries have promulgated laws and regulations strictly in the PVC products in the use of lead stabilizers, such as Health Canada 1994-48 document.
c , in Japan, the automobile industry association has launched a series of actions, in PVC products related to calcium zinc stabilizer instead of lead stabilizers, in 2005 has used lead thermal stabilizers used for the 1996 1/3. The SONY company has established green partner system, and begin to implement the technical standards in 2002 July 1, provisions in the plastic products in the lead content of no more than 100 x 10-6, Cd content of no more than 5 x 10-6.
C, China
a ,the state seven ministries in February 28, 2006 promulgated the "electronic information products pollution control management measures", the lead, cadmium toxic substances made similar RoHS instruction set, the information products of seven ministries jointly issued the document, on March 1, 2007 onwards;
b ,The national toy safety technical specification defines the migration of elements of the Doomsday in the toy materials, lead to 90mg/kg;
c ,Evaluation of the safety of drinking water distribution equipment and protective materials standards, including heavy metals Limited made significant changes: the amount of lead leaching is 200 times lower for ≤ 0.005mg/L; in 2004 the Ministry of construction notice clearly pointed out using nationwide water supply pipe UPVC pipe must be non lead salt stabilizer.But in August 1, 2006 began the new standard GB/T10002.1 implementation, indicate the drinking water pipes with PVC must be "non lead salt stabilizer production": the new national standard GB21550-2008 "PVC leatherette limit of harmful substances" implemented in March 1, 2009, limit should be less than 90mg/kg artificial leather lead content of soluble, soluble cadmium content should not be greater than 75mg/kg.
Undeniable regulations promulgated the policy of western industrial nations, are they in the technical maturity, the economy can bear case, and China enterprises pursue market share, is the product of the utility and use value, so can not actively respond to the development and application of alternative products., causing further environmental pressures increase in.Export situation deteriorated today, most enterprises will be at a loss what to do, the production ran into trouble. This again when we look into the environmental protection laws, decrees and the stabilizer, usage, we agent production and plastic products processing industry should have a long-term plan effectively, reduce or abandon the production and use of heavy metal stabilizer of lead and cadmium, modified to use more mature green stabilizer.
