To The Engineered Additives Website!
Engineered Additives, LLC offers its clients a cost efficient pathway to securing the polymers they use, the formulating support and analysis to effectively utilize those polymers and now, a unique family of compatibilizer compounds to assure efficient use of those chosen polymers in an asphalt formulation.
Engineered Additives, LLC, through the use of select chemistries and engineered rubber materials, now offers a broad selection of asphalt and polymer compatibilizers and modifiers for use in the paving and roofing material industries.
These products offer (1) improved SBS compatibility with asphalt, (2) broader application of beneficial additives, (3) enhanced compound characteristics for the end user, (4) incremental improvements in characteristics of base asphalts, (5) PG grade bump capability or significant performance improvement for paving without need of special equipment, (6) long-term effective use of recycled or renewable materials and (7) reduced costs to the user.

Working on roof |
Beginning with ground tire rubber (GTR), which is readily available from recycled tires, and processing the GTR by proprietary technologies to modify its composition and structure, Engineered Additives has developed several prototype products and compounds generically called Engineered Rubber Modifiers (ERMs) that dramatically alter the characteristics of various asphalts used in paving or in the manufacture of roofing products.
In addition to its proprietary ERM compounds, Engineered Additives, working in conjunction with its partners, can offer its customers, ready access to conventional polymers, as well as some unique modifiers, cross-linkers and additives for use by the paving and roofing industries.
Our proprietary materials will substantially improve polymer affinity in existing polymer modified asphalt formulations and yield a pathway to improving durability characteristics of base asphalt for uses in non-modified asphalt products. Use of these products does not require unique or expensive equipment by the end user. Many of our materials are available in liquid, powder or pellet form and will efficiently blend into asphalt with simple agitation and moderate applied heat.
In paving applications, our products offer reduced lay-down temperatures, lower emissions and a more durable pavement. In polymer-modified asphalt (PMA) formulations, our new efficient cross-linkers reduce costs and reduce SBS content. We offer more effective and lower cost alternates to well known products such as Sunoco Hydrolene™ or ExxonMobil Polybilt 101™.
Our products offer roofing manufacturers, lower emissions, reduced cycle times, increased line speed and lower energy costs. Our products allow use of PG Graded asphalt for built-up roofing asphalt (BURA) and potentially for shingles versus expensive asphalt flux in oxidation.
Our collective knowledge and experience in these market segments positions us well to assist our customers in providing the materials and the technical support that will work for them, regardless of the asphalt source. | ![]()
