Suppliers of polymer additives and functional chemicals
Safety, environmental protection, stability and efficiency are the core concepts of rookie brand. Since 2004, the supply of raw materials for additives has become a major problem in the plastic additive industry with the sharp rise in energy and raw material prices. Since the second quarter of 2004, additive production companies have been raising prices. Gastrock believes that the price of additives rises with the price of raw material companies, but the final profit does not increase. Some companies increase profits by reducing costs. Additive suppliers have been looking for ways to raise prices through products and after-sales service. One way to solve sales is to develop products with customers and solve some special use problems. Many companies are looking for new ways to develop new and valuable products. The manager of Dow Corning's global plastic additives marketing department reported that they were looking for important characteristics and ways to supply additives. JayGhosh, Market Research Manager of Plastic Additives Department of Ciba Specialty Chemicals Company in Basel, Switzerland, believes that in order to improve the competitiveness of products, additive suppliers should carry out quality innovation, such as durability, aesthetics, durability and biodegradability, from the application of Asian final products to product demand. The buyers of additives are concerned about the cost, and most of them consider the total cost of additives rather than the unit cost. For example, additives are used to reduce the cost of polymers such as polypropylene, hoping to compete with high-cost engineering resins; Processors are interested in additives to improve processing efficiency, hoping that they will have more output than existing equipment; Industry experts believe that cost-effective additive solutions can include efficient additives or additives mixed with customers' specific goals to avoid exceeding the characteristics of the project. High growth additives can be used in wood chip plastics (WPC) and long fiber reinforced thermoplastics (LFRT).
Gastrock believes that the merger and globalization of additive customers can improve global competitiveness by building customers' purchasing power; RichardSimpson, manager of manufacturing department of Akcross Chemical Company, believes that customer merger causes localization and customer-centric challenges, which requires globalization for suppliers; Global OEM industries, such as automobile and electrical appliance industries, have contributed to the globalization of polymer additive industry; Penny. Perry, the global marketing director of DuPont's industrial products, believes that the easiest way is to provide the same products worldwide and cancel the restrictions on additives; Industry experts believe that resin suppliers continue to simplify their grading system and promote additive users to mix and change accordingly.
The rapid growth of plastic market in China has promoted the consumption and production of additives in the Far East. Although China is an exporter of consumer goods, Gastrock believes that the region is still a net importer of plastics and plastic additives, and low-cost suppliers in China and Asia-Pacific have begun to meet the requirements of China. In addition, global additive companies are adapting to the rapid growth of China, mainly through joint ventures. For example, Ciba Specialty Chemicals Co., Ltd. and Yabao Co., Ltd. jointly established an antioxidant company, a PVC additive company with Chemson, and a flame retardant company with ICL industrial products. Some joint ventures are wholly owned by global companies, such as Akoma's PVC stabilizer company in Beijing, which started as a joint venture and eventually became a wholly-owned company; Other multinational companies have test laboratories and technology centers in China, or are investing.
Due to laws, regulations and environmental problems, the changes and development of the polymer additive market have been promoted. Simpson believes that because the development of products is always at the forefront of existing laws, we aim at the development requirements of future products; It meets the RoHS[ (Restriction of Dangerous Goods) requirements of the European Union and came into effect in 2006. RoHS restricts the use of lead as a stabilizer for PVC and polybromides as a flame retardant. Other European policies, such as WEEE and ELV, also restrict the application of heavy metals and halogen-containing materials. Especially in Europe, lead substitutes and halogen-free flame retardants are expected. Plasticizer, Europe is replacing di (2- ethylhexyl) phthalate [DEHP] with other phthalate plasticizers. In order to protect human health and improve the competitiveness of European chemical industry, the industry is conceiving the contract requirements and authorization procedures of EU chemical evaluation. European industrial members believe that the latter will encounter special challenges, mainly from the improvement of China's competitiveness. Simpson believes that European industrial associations, such as the European Stabilizer Manufacturers Association, play an important role in helping member companies meet the challenge of REACH. Dr. Gosh predicts that the recycling and biodegradation of additives will be promoted due to strict laws on handling plastic waste; In the agricultural market, the reduction of pesticides and the ban of methyl bromide fumigant have promoted the solution and use of agricultural plastic solvents.
stabilizing agent
Changes in rules and regulations drive changes in stabilizers. European PVC heat stabilizer manufacturers voluntarily promised that by 20 10, the amount of lead used as ethylene stabilizer would be halved to 20 15, and lead would not be used at all. In Europe, lead stabilizers are mainly replaced by metal mixtures of calcium and zinc. Organic stabilizers are another option, and it is expected that the use of lead stabilizers in the Asia-Pacific region will also decrease. The stabilizer of PVC in North American market is mainly tin stabilizer.
Volatilization restrictions of volatile organic compounds are becoming more and more strict. Simpson believes that there is a tendency to reduce volatilization in the application of vinyl flooring and automobile interior. Akcrstab's new products Akcrostab, barium-zinc mixture and calcium-zinc mixed metal stabilizer products have 100% activity, so it allows lower-grade applications and reduces volatilization. Ciba specialty chemicals company has introduced a liquid IRGASTAB stabilizer, which is specially designed to meet the volatility requirements of polyurethane for automobile interior decoration; In order to meet the application requirements of PVC and polyurethane, alkyl phosphite gradually replaced aryl phosphite.
Ghosh reported that, considering the impact on environment, health and safety (EHS), additives such as IRGASTAB, a new product produced by Ciba Specialty Chemicals Company, were used as solvent-free latex in PVC, MBS and ABS.
flameproof
With the strengthening of global safety and fire prevention standards, the amount of flame retardant is increasing, and manufacturers establish their company's brand image because of government regulations or voluntary. Especially in Europe, there is a growing demand for halogen-free flame retardants to replace halogen-containing flame retardants. Although brominated flame retardants have certain benefits in some applications, octabromodiphenyl ether and pentabromodiphenyl ether have been excluded from the Regulations on the Restriction of Hazardous Substances, and the application of decabromodiphenyl ether is expected to rank last in the Regulations on the Restriction of Hazardous Substances. REACH in Europe is used to evaluate whether new products meet OEM standards. LucvanMuylem, Vice President of Flame Retardant in Albemarle Company, found that high molecular polymers or bromine-containing flame retardants that are prone to chemical reactions have little micropore absorption and little toxicity in REACH estimation.
Flame retardants need high fluidity, processability and finally high service temperature. Small and thin electronic devices require high fluidity of materials and use at high temperature. Moreover, according to RoHS regulations, lead-free welding requires high fluidity. These factors require that polymer materials should have high-temperature resistant and high-temperature resistant additives, such as styrene bromide and high-temperature resistant aluminum hydroxide.
The traditional flame retardant polyurethane foam using octabromodiphenyl ether or pentabromodiphenyl ether is transformed into melamine resin or Saytex reactive bromine of Albemarle or a mixture of phosphorus and bromine flame retardant; Other researches on polyurethane foam focus on reducing coking and broadening the temperature range during foaming.
Nano-materials began to be used as synergists of flame retardants, and Albemarle recommended nano-clay mixed with 55%-60% magnesium hydroxide. Nano-clay reduces the amount of mineral flame retardant and maintains the properties of polymer materials. The next step is to increase the dosage of nano-clay and reduce the dosage of mineral flame retardant; At the same time, nano-clay is used as synergist of bromine-containing flame retardant.
Coupling agent and dispersant
Coupling agents, including titanate coupling agents and silane coupling agents, are used as modifiers for incompatible substances such as polymers and fillers. Silane also acts as a filler dispersant. Coupling agents increase with the increase of long fibers and other fillers in low-cost and high-performance polymers. Derry reported that with the growth of inorganic flame retardants, the filling amount of inorganic flame retardants is greater than that of halogen-containing flame retardants. In order to maintain the physical and mechanical properties of materials, coupling agents must be used, and new reinforcing agents such as glass fibers and nanocomposites all need coupling agents. Uchida reported that the dispersion of flame retardants and fillers is very important and continues to be the research direction.
impact modifier
In addition to coupling agents, impact modifiers are widely used in polymer materials. StephenHulme, manager of additives department of Acoma Company, thinks that the newly developed impact modifier is a low-filling, high-efficiency impact modifier, such as Durastrength produced by Acoma. Dupont also introduced a new impact modifier as a modifier for PET. Nano-materials are used as impact modifiers without reducing other properties of polymer materials, such as stiffness and transparency. The self-made block * * * polymer nano-strength produced by Arkema Company is in the pilot stage, and Hulme also thinks that nano-strength can be used to improve adhesives and epoxy resins.
