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
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.
Common injection molding, vacuum thermoforming machines and
sheet extruders are all can be used.
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
It also can be mixed with PP,
including T30S, F401, J340, B240, K8303, X30S, etc.
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 80ºC.
Its processing temperature is
5ºC to 10ºC 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.
