Processing
|
Do not need vulcanization,
high manufacture efficiency,
low energy consumption,few waste
|
Need compounding,banburying
and vulcanization, low manufacture
efficiency, high energy
consumption, great devotion
on equipment,workshop
and labor
|
Property
|
Excellent processing
technoglogy reduced the
instability of batch production
|
Bad combination property，
easy to be aged
|
Recycle
|
100% recycle of the
leftover material
|
Single color, can
not be thermowelded
|
Combined cost
|

No.27 document of Construction Department of P.R.C prescribed
that high filled soft PVC sealing strip must be forbidded to use on plastic
windows, doors and hardware……use sealing strip made by EPDM first. Pacrel
thermoplatic EPDM rubber has many advantages over the tranditional thermoset
rubber such as simple processing, low cost, recyclabe, and green. It has been
replacing the thermoset rubber gradually and widely used in the sealing strip
of doors, windows,and construction area.
