VIRGIN granule MDPE RESIN
VIRGIN granules
The structure has a glass transition temperature of about 210 ° C, a melting temperature of 257 ° C and a density of 0.96 to 1.06 g / cm 3. Practical polyphenylene ether molecular weight of 2 to 5 million, about 50% crystallinity. The most prominent advantage is a high degree of water resistance and resistance to steam. It can be processed in high-pressure steam container at 132 ºC for 200 times and has no significant change in tensile and impact strength. Besides, it has the characteristics of good dimensional stability, small creep, high insulation, etc., and long-term use temperature is -127 ~ 120 ºC , No load intermittent work up to 200 ºC, and the general level of thermosetting plastic quite.
Polyphenylene ether from 2,6 - dimethyl phenol in the copper salt (such as cuprous chloride) and amine under the action of the catalyst, in air or pure oxygen for the oxidative coupling polymerization.
Polyphenylene ether easy processing molding, extrusion, injection and molding can be. Used in the manufacture of medical equipment instead of stainless steel, can withstand steam disinfection, but also for mechanical and electronic components, insulation materials. Polyphenylene oxide and polystyrene blends modified products in the United States trade name Noryl, and can add 20% to 30% glass fiber, carbon fiber and other enhancements, is an excellent performance of engineering plastics and insulating materials.
HDPE Raw Material,HDPE virgin granules
HDPE resins are produced with low pressure gas phase process. The products are primarily used for extrusion application such as flat Yarn, coarse monofilament, film & sheets and injection molding such as pallets, crates, bottle caps and industrial containers.
