Main applications:
Dehydration (drying agent) master batch is a kind of advanced functional
master batches developed to solve moisture problem. It can dramatically
absorb the moisture from plastic during molding process. Foam, gradation,
crack, dot problems raised by moisture will be solved through add dehydration
MB. It can keep product quality and yield to improve productivity and reduce
cost. Meanwhile there is no bad effect to product physical mechanical quality.
Features:
1) Absorb 20% equal to its own weight moisture
2) Easily use normal equipment, no change of process technique
3) No harm, no irritant, good plasticization property, granule
form, equal in size and shade
Application ratio and method:
Mix these series master batch with the stuff resin at ratio of 1:20 to 1:100,
normally 1:50, no boasting material needed when moisture is below than
1%, (different ratio decided by the product moisture ratio), after simply stirring
the mixture to homogeneous (no addictive agent needed), we can get the
final products as we want. If moisture is higher than 1%, please dry material
firstly to lower than 1%, then dehydration master batch can be used.
Remarks:
It should be stored in ventilated, dry and cool place. Damage on packing is
not permitted. After opening the packing, left master batch should be sealed immediately to keep dry. After mixing with material, we suggest using out within
24 hours.
It is widely used for recycling material, damped plastic and degraded plastic
of PP, PE, PVC and PS during molding process
