DPR Liquid Natural Rubber |
|
The DPR products
are low molecular weight, liquid polymers of natural rubber. The
chemical backbone is cis-1,4 polyisoprene. DPR liquid rubber
offers processing flexibility and performance options for a wide
range of applications. Liquid natural rubber improves rubber and
polymer compounding and final processing. It acts as a
plasticizer to reduce cycle time and energy consumption. Since
it cures by the same mechanism as natural rubber, it becomes
part of the polymer matrix and remains non-fugitive. This
extends the life of the finished products.
Typical Applications
DPR liquid rubber provides all the performance properties of
natural rubber in a convenient liquid. Liquid rubber performs
many functions in a wide range of applications:
- Reactive rubber processing aid
for the Tire Industry
- Polymer binder for grinding wheels and friction products
- Reactive vehicle for rubber additives
- Rheology modifier for lubricants
- Polymer base for molding and tooling systems
- Polymer base for electrical encapsulants
- Polymer base for automotive sealants and sound damping
compounds
- Asphalt modifier
