PETG media bottles have very good gas barrier properties and are often used to store and sample active pharmaceutical ingredients and bulk intermediates. They are also ideal for preparing and storing liquids such as buffers, serum, and various media. 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 30%-40%. Has good viscosity, transparency, color, chemical resistance, and resistance to stress whitening. Quickly thermoformed or extrusion blow molded. Viscosity is better than acrylic (acrylic).
The PETG culture media bottle made of this raw material has high transparency and excellent impact resistance. This material is particularly suitable for forming thick-walled transparent products. It has excellent processing and forming performance, and can be designed in any shape according to the designer's intention. Traditional extrusion, injection molding, blow molding and blister molding can be used. It is used in the market of sheet material, high-performance shrink film, bottle and profile material, etc. At the same time, its secondary processing performance is excellent, and conventional machining modification can be carried out.
The above are the material characteristics of the PETG media bottle. 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.
