Polymer Modified Bitumen Plants
Polygonmachine PPB Series – Polymer Modified Bitumen (PMB) Plants
Polygonmachine PPB Series Polymer Modified Bitumen (PMB) Plants are engineered for the production of high-performance road binders by blending conventional bitumen with polymers such as SBS, EVA, SBR, crumb rubber, and other modifiers.
With advanced high-shear mixing technology, thermal oil heating, and fully automated process control, the PPB Series ensures stable, homogeneous, and specification-compliant PMB for highways, airports, heavy-duty pavements, and specialized asphalt applications.
These plants offer exceptional reliability, high operational throughput, and superior temperature control, making them the preferred solution for modern asphalt modifier production.
