Carbon dioxide polym
2、er materials as the main raw material has been turning the waste into treasure, it is the most important green ecological to save and substitution petroleum resources materials. Carbon dioxide is based on polymers from raw materials acquisition, product manufacturing, ecycling use, and waste disposa
3、l. It is also good for other part of the earth environment load minimum and harmless to human body health. Carbon dioxide polymer prompts to reduce the resources and energy consumption, also makes low pollution of the ecological and environmental. Carbon dioxide polymer is regeneration efficiency hi
