PAE, also known as phthalate esters, is a general term for esters formed by phthalic acid. When used as plastic plasticizer, it generally refers to the ester formed by phthalic acid and alcohol containing 4 ~ 15 carbons. Dioctyl phthalate is the most important variety.
Phthalates are widely used plasticizers, which can modify or soften plastics. They are ubiquitous in plastics and paints, mainly in PVC and paints. Among them, 15 kinds of phthalates are considered as harmful substances, and their use is restricted.
The concentrations of DEHP, DBP, BBP, DINP, DIDP and DNOP must not exceed 0.65438 0%.
2- ethylhexyl phthalate (DEHP)
dibutyl phthalate
(BBP) butyl benzyl phthalate
(DINP) diisononyl phthalate
Di-n-octyl phthalate (DNOP)
(DIDP) diisosunflower phthalate
The directive 2005/84/EC on phthalate esters issued by the European Union came into effect on June 65438+10/October 65438+June 2007. According to the directive, the sum of the mass percentages of DEHP, DBP and BBP in all plastic materials of toys and toys and children's products shall not exceed 0.1%; For the plastic materials of toys and baby products that can be put into the mouth, the sum of the mass percentages of the other three phthalates DINP, DIDP and DNOP shall not exceed 0. 1%.
Question 2: What does the EU environmental standard eo mean? It is an environmental protection standard representing formaldehyde emission level. Internationally, the * * * levels of formaldehyde are divided into E2, E 1 and E0 (E2≤5.0mg/L, E 1≤ 1.5mg/L, E0≤0.5mg/L). Compliance with E0 is the highest level standard.
Question 3: What is the standard of EU environmental certification? The white swan in northern Europe and the European flower in the European Union.
Question 4: Does the EU secondary environmental protection standard include REACH? Including, I need to reach out and detect LX.
Question 5: What is the difference between e 1 environmental protection standard and European E1environmental protection standard?
E 1 environmental protection standard is a national mandatory health standard and a mandatory "safety standard line". E0 standard is the highest international health standard at present. Because the formaldehyde content of 0.5mg/l is already a very safe numerical standard. Relevant data show that the formaldehyde content of drinking water is 0.9mg/l, which means that the formaldehyde content of E0 standard is less than that of drinking water.
European environmental protection standards E 1: all are standards for free formaldehyde content of plates, in which the free formaldehyde content of E 1 grade is ≤9mg/ 100g (other standards: E 1 grade ≤ 1.5mg/L,)
Harm of formaldehyde to human body
1. Effect on skin: Formaldehyde is internationally recognized as a potential carcinogen, and its main harm is its * * * effect on skin and mucosa. Formaldehyde is a protoplasmic toxic substance, which can combine with protein when inhaled in high concentration, causing severe respiratory tract edema, eyes and headache.
2. Human sensitivity: Direct skin contact with formaldehyde can cause allergic dermatitis, pigmentation and necrosis, and inhalation of high concentration formaldehyde can induce bronchial asthma.
3. Mutagenesis: High concentration of formaldehyde is still a genotoxic substance. Experimental animals can cause nasopharyngeal tumors under the condition of high concentration inhalation in laboratory.
4. Outstanding manifestations: headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, loss of appetite, palpitation, insomnia, weight loss, memory loss, autonomic nervous disorder; Long-term inhalation by pregnant women may lead to fetal malformation and even death.
Using super E0 grade board, no glue containing formaldehyde is used in the production process, which is almost the same as the formaldehyde content of pure natural fresh wood in the natural state. E 1 level is equivalent to formaldehyde emission of 1.5 mg/L, and our national standards are formulated with reference to this data. The formaldehyde emission of E0 grade board is 0.5 mg/L, which belongs to high-grade products and is generally only used in special places, such as hospitals. The formaldehyde content of super E0 grade plate is close to zero, and it has not yet entered the national standard, which is a stricter standard for the environmental protection performance of its products.
Question 6: What is the EU standard for standard parts? RoHS is a mandatory standard formulated by EU legislation, and its full name is Restriction of Hazardous Substances in Electronic and Electrical Equipment. This standard was formally implemented on July 1 2006. It is mainly used to standardize the materials and process standards of electronic and electrical products, making them more conducive to human health and environmental protection. The purpose of this standard is to eliminate six substances of lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in electronic and electrical products, emphasizing that the lead content should not exceed 0. 1%. The main sources of lead involved are as follows.
[Edit this paragraph] Basic contents of EU RoHS and WEEE directives
On February 3, 2003, 13, the European Parliament and the European Commission issued WEEE and RoHS directives on restricting the use of certain harmful substances in electronic and electrical equipment.
RoHS directive and WEEE directive stipulate ten categories 102 products, and the first seven products are the main export electrical products in China. Including large household appliances, small household appliances, information and communication equipment, consumer goods, lighting equipment, electrical and electronic tools, toys, leisure and sports equipment, medical instruments (except implanted or infected products), monitoring and control instruments and vending machines.
[Edit this paragraph ]RoHS directive restricts the use of the following six harmful substances
1 mercury (mercury) Examples of using this substance: thermostats, sensors, switches and relays, and light bulbs.
Examples of lead using this substance: solder, glass, PVC stabilizer.
Examples of cadmium using this substance: switches, springs, connectors, housings and printed circuit boards, contacts and batteries.
Example of chromium (hexavalent) using this substance: metal with corrosive coating.
Five examples of PBBs using this substance: flame retardant, PCB, connector, plastic shell.
6 PBDE examples of using this substance: flame retardant, PCB, connector, plastic shell.
[Edit this paragraph] Test principle:
According to the EU WEEE &；; RoHS directive requires AOV to classify products according to materials and detect harmful substances with different materials. Generally speaking:
? Metal materials need to detect four harmful metal elements, such as (cadmium, cadmium, lead, mercury, mercury, Cr6+ hexavalent chromium).
? In addition to these four harmful heavy metal elements, we should also test the brominated flame retardant (PBDE) of plastic materials.
? At the same time, packaging materials with different materials also need to be tested for heavy metals (94/62/EEC).
The following are the upper limit concentrations of six harmful substances specified in RoHS:
Cadmium: less than 100ppm
ROHOS lead: less than 1000ppm.
Less than 2500ppm in steel alloy
Less than 4000ppm in aluminum alloy
Less than 40000ppm in copper alloy
Mercury: less than 1000ppm
Hexavalent chromium: less than 1000ppm
[Edit this paragraph] Why should RoHS be introduced?
In 2000, when cadmium was found in the cables of some game machines sold in the Dutch market, people first noticed that electrical and electronic equipment contained heavy metals harmful to human health. In fact, solder and ink printed on packaging boxes widely used in the production of electrical and electronic products all contain harmful heavy metals such as lead.
[Edit this paragraph: When will RoHS be implemented?
The EU will implement RoHS on July 1 2006. At that time, electrical and electronic products using or containing heavy metals and flame retardants (such as PBDE and PBBs) will not be allowed to enter the EU market.
[Edit this paragraph] What products does RoHS specifically involve?
RoHS is aimed at all electrical and electronic products that may contain the above six harmful substances in the production process and raw materials, mainly including: white goods, such as refrigerators, washing machines, microwave ovens, air conditioners, vacuum cleaners, water heaters, etc. Black household appliances, such as audio-visual products, DVDs, CDs, TV receivers, IT products, digital products, communication products, etc. Power tools, electric electronic toys and medical electrical equipment

Question 7: Seeking help from EU standards At present, Europe is actively applying for environmental protection certification from food to daily consumer goods, and strictly restricting the selection of raw materials, production technology and environmental protection factors during use. At present, Europe is the most authoritative and widely promoted environmental label certification.
In 1992, the EU formulated the environmental protection label system, which was revised in 2000. Through the European Parliament and the Council, the scope of products will be extended to all consumer goods (excluding food, beverages and medicines) and service industries, so as to encourage producers to design products with environmental protection ideas through the certification of this label, and at the same time let consumers know about their consumer products.
In order to promote this environmental label, the European Commission and the Ministry of Environmental Protection of Britain and Ireland jointly organized a one-week "European Flower Week" with environmental groups, consumer groups and manufacturers from Austria, Belgium, Denmark, France, Italy, the Netherlands, Sweden, Finland and Norway from June 5 to October 8, 2004.
Some EU member states actively promote environmental labels. At present, the EU Eco-label Committee has planned that the future eco-label plan will include more than 30 kinds of products such as garbage bags, plastic bags, shopping bags, telephones, photocopiers, sporting goods, leather products and small household appliances.
