  Product Type :
. . Injection Grade Starch Based Biodegradable Resin
    Compliance with :
   

ISO15855 - OK BIOBASED

The degradation ratio more then 46% in 100 days

   
   
   
     
 

Product Futures :

Granules are in light yellow and come in cylinder and round shape, with slight fragrance. They absorb moisture easily and are easily decomposed by microbes. They are anti-static. The processing temperature of them is lower than that of conventional plastic. They are easily colored. Such resin can be processed into finish products alone without adding any other polyolefin materials like PE, PP, PVA, EVA, etc

 

Recommended Applications:

This resin can be directly molded into finish products. Its melt flow rate is high. So it is suitable to make all kinds of containers, like plant nursery pots and bowls, soya bean curd trays, agricultural pesticide bottles, shampoo and shower gel bottles, straws, toys, packaging boxes and all sorts of disposable containers.

 

       

 

Processing Equipment:

Common injection molding, vacuum thermoforming machines and sheet extruders are all can be used.

 

Processing Technology

Newly molded products feel crispy and fragile due to severe dehydration during production. After 24 hours of curing time, molded properties and hardness will increase noticeably.

It also can be mixed with PP, including T30S, F401, J340, B240, K8303, X30S, etc.

 

Remanks:

Due to the high starch content, the resin easily absorbs moisture. So it needs to be stored in a dry environment. The package should also be sealed properly to prevent the ingress of moisture.

 

In case the resin is damp, it should be dried for 2 hours at 80C. Its processing temperature is 5C to 10C lower than that of PP. During processing, the temperature is correct when corn starch fragrance can be smelled at the hopper.

 

It can be easily decomposed into soil friendly substances in microbial environment.
