PVC Heat Stabilizer Zeolite
Jiahe specialty zeolites are an important part of the plastics and
polymers industry where they act as excellent co-stabilizers for
PVC and other applications. Jiahe PVC Heat Stabilizer zeolite is
part of a new green technology to produce and place asphalt mix at
temperatures 50° to 70° F lower than traditional hot mix asphalt.
This means lower emissions, reduced energy use, improved
workability, and road compaction.
Zeolite contains more porous molecular structure,so have Strong
adsorption on HC1,In the development process of the
stabilizer,zeolite thermal stability inhibits the burning of zinc
and to improve the processing performance plays an important
As can be seen from the table 1: With the improvement of zeolite
usage, increase in porous structure, improve the ability of the
adsorption HC1, Thus Inhibition of auto-catalytic, To prevent off
hc1 and polyene structure generation, Capture free radicals,to
prevent oxidation, destruction of large conjugated system,
effectively prevent PVC degradation, delay material discoloration.
As can be seen from the table 2 and table 3: With the improvement
of zeolite usage, the dynamic thermal stability gradually increase,
balancing torque is gradually reduced, this is because the zeolite
have the effect of lubrication, it can improve the flow of
materials in the process, improve surface stripping, so play a
secondary stabilizing effect. when the zeolite content reaches 14,
PVC sample dynamic thermal stability for more than 20 minutes,
Balance torque is 16.0N.m,not only save the cost of formula,but
also ensure the comprehensive performance of the product.
