HC plastic mesh News: first application is also an effective stabilizer system for cadmium and lead, the result of environmental hazards in the country has been partially banned. According to the requirements of the global ban of lead, lead, cadmium products eventually will be phased out around 2015. How to reduce lead metal PVC Products in production and recycling process and related personnel on the environment caused by pollution and hazards, is a serious problem. China PVC Plastic Products And international standards is a general trend in the current economic downturn conditions, to achieve lead-free, low-lead plastic products can also satisfy the economic, technical indicators, and easy to use, efficient, Environmental protection And economical, this is also a number of research institutions and enterprises to increase investment to strive to meet the global environmental protection requirements, took away the impetus of domestic and international business opportunities.
Heat stabilizer The development of the last century 80's, with a large number of imported plastic processing machinery, plastic additives of new technologies, new products have entered China. As for the production of soft leather LC-90 (U.S. shamrock china produced cadmium / zinc reminder foam stabilizer), for the production of foam wall wallpaper potassium / calcium high foam stabilizer (Akzo Company product) and so on. These products brought us new ideas and perspectives of the same processing as well as our current heat stabilizer varieties, the origin of hybrid systems. Objective analysis of the current domestic situation If the heat stabilizers lead, cadmium products are environmentally friendly products exclusion has formed an organic tin (including compound products), calcium / zinc (that is compounded products), rare earth compound, etc. three systems, of course, there are organic stabilizer domestic R & D, application reports. The production and identification with, at present, or calcium / zinc products ranked first; but the composite utility Organotin stabilizers Organic tin product is a major development trend is consistent with China's actual situation; of course, rare earth products, especially the current release of rare earth / calcium zinc products is a major bright spot.
Ca-Zn heat stabilizer compound is recognized as the world's non-toxic, environmentally friendly heat stabilizers, and has low price, good lubricity, etc, with a very broad space for development, Ca-Zn heat stabilizer compound is the use of two who has a synergistic effect, making in recent years Composite Stabilizer The most active areas. World-renowned manufacturer of heat stabilizers are the product launch. The domestic companies are catching up through the head in different ways, such as Wenzhou Tin Shing, Hebei Grey, Nanjing Jinling, Shenzhen Zhi sea, Zhaoqing Ding Lake and other enterprises, in powder, paste, liquid and other environmental products development, application achieved good results.
Development and application of auxiliary stabilizer is a heat stabilizer of one of the hotspots, such compounds have phosphite, polyol, epoxy compounds, -diketones, organic material and inorganic stable hydrotalcite, etc. . Stability in organic matter of the application of the United States, particularly Chemtura Introduces hardware products for PVC processing of organic products?? OBS. Organic stabilizer compounds from the organic bases, such as the amino-uracil, and 5 dihydropyridine ring 1,3,4 - oxadiazole derivatives, extract, these substances have competitive prices, while lower in performance migration, low odor, good pre-hue, excellent transparency. Organic stabilizer stabilizer by inhibiting cross-linking of molecular chains in the processing of PVC products, the high temperature and under high shear processing time, much better than lead type and calcium / zinc soap stabilizer system, the existing domestic homes The enterprise back in a few years ago put a lot of people, financial, and material, to obtain certain results.
Finally, we should also see that since the end of 2007 to the present, due to global Financial Crisis, the domestic economy showed downward trend, plastic products have been hit harder is a step back in 2007, Guangdong exported toys recalled due to excessive paint sparked global Mattel toys in China "crowding out" wave , 2008, relating to plastic bags and other "white pollution" caused by "limit of plastic that" the two incidents causing more than double-digit decline in domestic toy production and Qi Cheng plastic stop factory. Relatively heat stabilizer industry the impact is not great, but very far-reaching impact on the industry. Heat stabilizer industry to lead, tin and other metal, stearic acid as the main raw material price fluctuations turns, raw materials prices surge almost never stopped, to downstream processing and manufacturing enormous cost pressure, which we state of additives in low-profit basic production enterprises, more difficult. I am an expert from China Chemicals Products, usually analyzes all kind of industries situation, such as adjustable roller skates , hockey inline skate.
