It was learned from the State Intellectual Property Office that in the field of new energy vehicles, China’s independent innovation capability has made a big leap forward: in the past 7 years, China submitted a total of 2011 patent applications, ranking third in the world with Germany and South Korea. The first two countries in the world are Japan and the United States. The number of patent applications is nearly 9,000 and 4,000 respectively.
As of the end of 2012, China has demonstrated the promotion of 27,400 energy-saving and new energy vehicles. It is reported that the development of new energy vehicles, patent applications and protection is a "lifeline." Taking the production of lithium iron phosphate car batteries as an example, if a foreign company obtains an effective invention patent, the production of a domestic enterprise needs to obtain a foreign patent license, and a one-time payment of 10 million US dollars or a production of 2500 US dollars per ton of product.
It is reported that China has recently increased its input in the field of new energy vehicles. According to the “Twelfth Five-Year Planâ€, the 863 Plan, and the Science and Technology Support Plan, 39 R&D projects in the field of new energy vehicles have been arranged, with investment exceeding RMB 5 billion. Develop key technologies such as new energy vehicle models and power batteries with independent intellectual property rights.
Composite Nylon Plastics Material POM
1 What's Polyoxymethylene (POM) ?
Polyoxymethylene (POM), also known as acetal , polyacetal, and polyformaldehyde, is an engineering thermoplastic used in precision parts that require high stiffness, low friction and excellent dimensional stability.
2 Properties
♣POM is characterized by its high strength, hardness and rigidity to -40 °C. POM is intrinsically opaque white, due to its high crystalline composition, but it is available in all colors.
♣POM homopolymer is a semi-crystalline polymer (75-85% crystalline) with a melting point of 175° Celsius
♣POM copolymer has a slightly lower melting point of 162 – 173° Celsius.
3 POM advantages
♥High abrasion resistance
♥Low coefficient of friction
♥High heat resistance
♥Good electrical and dielectric properties
♥Low water absorption
