PETG media bottles have very good gas barrier properties, and are often used to store and sample active pharmaceutical ingredients and bulk intermediates, and are also very suitable for preparing and storing buffers, serum, various culture media and other liquids. Such a wide range of applications is mainly due to the various excellent properties of its raw materials.
PETG is an amorphous copolyester. With the increase of CHDM in the copolymer, the melting point decreases, the glass transition temperature increases, the crystallinity decreases, and finally an amorphous polymer is formed. Generally, the content of CHDM in PETG is more suitable at 30%-40%. Has good viscosity, clarity, color, chemical resistance, and stress whitening resistance. Can be quickly thermoformed or extrusion blow molded. Viscosity is better than acrylic (acrylic).
The PETG media bottles made of this raw material has high transparency and excellent impact resistance. This material is especially suitable for forming thick-walled transparent products. Its processing and forming performance is excellent, and it can be designed in any shape according to the designer's intention. It can be formed by traditional extrusion, injection molding, blow molding and blister molding. It is used in the markets of board and sheet, high-performance shrink film, bottle and profiled materials. At the same time, its secondary processing performance is excellent, and it can be modified by conventional machining.
The above are the material features of the PETG media bottles. As a storage container for various medium, this bottle is processed into a square shape, which conforms to the characteristics of human mechanics and is easy to grasp.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
