Masterbatch industry: it is difficult to survive without standards

LUO Chongyuan, chairman of Guangdong shenghengchang Chemical Industry Co., Ltd., which specializes in the production of masterbatches, has been very annoyed recently. Because a downstream plastic product customer proposed to sign a letter of association with him. If you don't sign, the customer will give up their cooperation with Huafeng spandex. Luo Chongyuan just didn't dare to sign. When he curiously inquired into Luo Chongyuan about this, he learned that it was not only this enterprise that was equally troubled, but the entire color masterbatch industry. The crux is that for 30 years, the industry has failed to set a national standard for its upstream raw material supply

there is no standard era: "each manufacturer makes the same pigment differently"

Luo Chongyuan told CCIN gloomily that his domestic customer is making plastic products for coffee pots, toasters, etc., which are mainly exported to EU countries. In recent years, plastic products are often recalled because they contain chemicals prohibited by EU regulations, and the frequency is increasing, so the customer proposed to sign a joint letter with him. If it is found that the color masterbatch contains prohibited substances, he will bear the relevant responsibilities. "But the problem is that some harmful chemicals are not produced in the production process of Color Masterbatch, but brought by upstream raw material pigments!"

ask: "then why not continue to sign a joint letter with the upstream pigment supplier? If it is found that the pigment contains prohibited substances, then the pigment supplier will bear the relevant costs?"

"up to now, there is no national standard restricting pigments in the color masterbatch industry. You say this ingredient is harmful, and people don't recognize it. How do you say we can provide valuable escape time?"

it is understood that color masterbatch, also known as pigment concentrate, is a particle made of pigment and plastic in a certain proportion, which is applied to the coloring of plastic products. It changes the traditional way that pigments directly color plastics, not only eliminates the pollution caused by pigment dust emission in technology, improves the production environment, but also contributes to the uniform coloring of plastic products in product quality. As soon as the color masterbatch came out in the United States in the 1950s, it has been rapidly popularized, and the market space is becoming wider and wider. In the early 1970s, China successfully developed color masterbatches in Petrochina Lanzhou Petrochemical Company and put them into mass production. With the increasing demand for plastic products at home and abroad, color masterbatch technology has also become a mature and unique material processing technology

Qiao Hui, Secretary General of the professional committee of color masterbatch of China Dyestuff Industry Association, said that color masterbatch is equivalent to monosodium glutamate of plastic products. Whether plastic products can be upgraded depends on the color masterbatch. Therefore, although in China, the color masterbatch industry is only a small industry with an annual output of only 600000 tons and an annual output value of only 10billion yuan, and the vast majority of enterprises are private enterprises, stimulated by the rapid development of the plastic products industry, the development of this small industry in recent years is also rapid. According to the statistics of the color masterbatch special committee, there are about 4500 domestic production enterprises, mainly distributed in Guangdong, Jiangsu, Shandong, Zhejiang, Shanghai and other places

"Pigment is the raw material of color masterbatch. The quality of pigment directly affects the quality of Color Masterbatch, and the quality of Color Masterbatch directly affects the quality of plastic products. In other words, the requirements of plastic products for Color Masterbatch, that is, the requirements of color masterbatch for pigment. This includes safety, heat stability, light and weather resistance, acid and alkali resistance, migration resistance, chemical resistance, etc. but the pigments used for Color Masterbatch have not been developed in the world The home standard has been the standard for pigments used in paints for 30 years. " Qiao Hui said helplessly

it is understood that in the past 30 years, color masterbatch enterprises and pigment enterprises have also been at peace. But in recent years, there have been more and more problems, even to the point that it is difficult for Color Masterbatch enterprises to survive

songhuichun, general manager of Daqing Zhongyi Cable Material Co., Ltd., complained that the standards of pigment enterprises are diverse, high and low. In recent years, he often encountered the situation that the color masterbatch products did not meet the requirements and were returned due to the quality of pigments

"every manufacturer makes the same pigment differently." Hong Yin, deputy general manager of Ningbo masterbatch Co., Ltd., complained that downstream customers are always looking for problems in safety and environmental protection, such as containing internationally banned chemicals. "When our masterbatches are exported, because we have no bottom in mind, we need to spend a lot of money on testing, and the annual testing cost is more than 200000 yuan."

Chen Weiguo, general manager of Shandong Luyan Color Masterbatch Co., Ltd., also felt the same: "The masterbatch is produced with paint according to the paint, which itself has an annular groove at the top of the tank. It's unscientific. People paint on the wall, but the masterbatch is mixed in plastic. How can it be the same? In order not to have a problem, we also spend a lot of money to send it to other institutions for testing to see whether the paint contains substances that are not suitable for plastic products."

CCIN interviewed the head of a large domestic pigment enterprise. When CCIN fed back the complaints of Color Masterbatch enterprises, the person in charge admitted that they had no relevant testing instruments specifically for the application of Color Masterbatch at all, "the state has no standards for the production of pigments for color masterbatch. What can we do?"

the era of standards: "standardizing source materials has become more and more urgent"

for the color masterbatch industry, the bigger trouble is that with the rising awareness of global environmental protection, countries have increasingly stringent requirements on the control of harmful substances in imported products

it is understood that Europe, the United States, Japan and other developed countries have formulated laws and regulations to control chemical substances in plastic materials and their products, such as RoHS directive and reach regulation of the European Union. Health and safety standards related to human health and food contact materials are also included in the regulatory content. Such as German lfgb, French food FPL, American FDA, Japanese food jhpa, Chinese GB, etc. Most of the regulatory content of all these laws and regulations focuses on plastic and plastic colorants and additives and other source materials

the strengthened implementation of laws and regulations such as environmental protection directives and safety standards has had a far-reaching impact on the entire plastic industry chain. From the in-depth analysis of the plastic processing industry chain, it is found that heavy metals, bromide, phthalates and other chemicals in plastic products that may cause harm to the environment and human body come from plastic additives, such as color masterbatches, flame retardants and so on. Therefore, whether the color masterbatch can meet the requirements of relevant laws and regulations, the selection standard is becoming more and more important. "Standardizing source materials is becoming more and more urgent." Wang Zhuo, chairman of China Dyestuff Industry Association, expressed concern

Luo Chongyuan said eagerly, "now the main plastic customers have proposed that the color masterbatch should meet several international standards, such as RoHS directive, reach regulations, etc., and more and more customers have put forward similar requirements. I can tell people that we haven't even set a standard before leaving the factory?!"

wangzhongwen, chairman of Zhejiang seven color deer masterbatch Co., Ltd., said that developed countries attach great importance to the standards of pigment products, have specific regulations on various indicators of pigment products, and have unified test data. Like cooking, KFC is a kind of taste in Hangzhou or Beijing. In China, what we talk about is experience. Different places and enterprises make different products of the same model. If we want to enter the international market, we can only follow their regulations and standards, otherwise we can't export

song Huichun also made a comparison: "The pigment standards for masterbatch in developed countries are very perfect. The pigment specifications of world-famous pigment manufacturers such as Clariant, BASF and so on are very detailed. The data of domestic pigment manufacturers are generally copied, and they have not done the corresponding inspection at all.

the pigment enterprises are also aware of the complaints and eagerness of domestic masterbatch enterprises, and some enterprises are also consciously adjusting. Hangzhou Baihe Hua Group Co., Ltd. is a leading enterprise in the domestic pigment industry. Xuanyongjun, deputy general manager of the enterprise, told CCIN that plastic, paint and ink are the three major application fields of pigments at present. But at first, pigments developed closely with inks and coatings. At present, many pigment products are still made for inks and coatings. "In recent years, we have gradually realized that color masterbatch is the downstream industry we will focus on in the future. We spent a lot of money to buy some instruments, first in hardware, and then in research and development. The original process of pigment production was quite blind, and now we need to control it through instruments, hoping to keep pace with internationally renowned pigment enterprises."

at a time when domestic color masterbatch manufacturers are becoming more and more uneasy about the lack of standards, recently there have been a series of cases in which pigments exported to Europe and the United States have been returned due to excessive metal ions

why has the color masterbatch industry not put forward standards for its upstream in the past 30 years? Is it a technical problem or something else

according to Wang Zhuo, in the past, people didn't have high requirements for plastic products, nor did they highlight the requirements of safety and environmental protection. Therefore, the masterbatch industry can make do without standards. However, at home and abroad, the control of product indicators such as product color and safety is more and more strict, and the level of upstream pigment enterprises is also more and more uneven. In this contrast, the demand for pigment standards in the color masterbatch industry is urgent
