Bio-degradable masterbatch:

1,Product introduction The biodegradable fillermasterbatch,which is developed by our company as a thousand-tonindustrialization project,is listed in the 13 Tianjin keyindustrialization projects of science and technology,and also beapproved as a technological achievements industrialization projectby the State Plan Commission.Biodegradable filler masterbatch asour flagship product has the following features:1,The originalstarch,which has been added with sterification agent andplasticizer,is compounded to modified starch.These additives,namelysterification agent and plasticizer,can increase the dispersity ofstarch in polyethylene and decrease the property differences amongeach constituents of starch-PE.This can not only raise the additionamount of starch in PE,but also improve the mechanical propertiesof combined blending film products.2,Biodegradable masterbatcheshas well solved the common problem of blending compatibility ofstarch and PE by adopting special technological process.Thanks tothe secondary modification of starch,the starch content of ourbiodegradable masterbatches can be up to 70%,and the additionamount of biodegradable masterbatches in plastic products can reach60%.These plastics can be biodegraded into environmental freefragments by microorganisms,and eventually digested by naturalenvironment.Our company''s biodegradable masterbatches can bewidely applied into industrial packaging films,agriculturalfilms,food packaging films,shopping bags,bin bags,PE sheetmaterials and PE plate materials,and can also further processed tomake various kinds of extruded products,suction molded products andinjection molded products.Except from biodegradable function,ourbiodegradable products have almost the same physical and chemicalproperties of ordinary plastic products.2,Technical indexes A,Itshows a better plasticizing appearance with consistent color.Itexposes as regular granules with impurity free.B physical andchemical properties Density 1.105±0.1g/m3 volatile matter?4 MeltFlow Index?8.0g/10min 3,Degradation mechanism Biodegradablemasterbatches can be used as fillers to produce plasticproducts.These plastic products can also be influenced by thecombined action of sunshine,hydrothermalwater,oxygen,microorganisms and blown sand''s mechanical force inthe natural environment.After a certain period,biodegradablemasterbatches can decrease plastic products''macroscopicstrength,significantly reduce their molecular weight,and make themeasily degradable by microorganisms.When molecular weight islowered down to a certain extent,materials become brittle,start todisintegrate,and are eventually digested and absorbed by theenvironment.Thus the goal of reducing environmental pollution canbe reached.4,Using Method a,When used to the blow mounding ofbiodegradable agricultural film,LLDPE and LDPE can be used as mainbase materials with the addition amount of biodegradablemasterbatches no less than 15%;b,When used to the blow mounding ofbiodegradable packaging film,LLDPE and LDPE can be used as mainbase materials with the addition amount of biodegradablemasterbatches no less than 25%;c,If any physical properties can nomeet the standard,adjustment of formula component can work outthoroughly.d,Masterbatches should not be exposed to air for a longtime during the process of application.5,Storing conditions Keep itin a low-temperature aeration drying environment.Packaging damageand exposure are not allowed.
