Molecular formula : MW : CAS :
nature : be microbial degradation of plastics used for a short time only plastic supplies, such as agricultural plastic film, life for one-time use plastic bags, cups, boxes not because of its stability and degradation as solid waste cause great environmental problems -- white pollution. These biodegradable plastics through the plastic inserted the light sensitive groups, activity groups, polymer chain length conditioning agents additives, in the sun under the polymer main chain gradually broken and become more brittle and subject to rain or other role it crumbled into small films, this will benefit the soil microorganisms to breakdown Solution into water, carbon dioxide, chlorine and carbon material and simple purification.
