Our mission is to create a HSE compliant polymer modified asphalt cross-linking system with non-sulfur additives. Through innovation and sustainable practices, we aim to deliver simpler, safer and cost-effective solutions in the PMA paving / roofing manufacturing process.

Canaphalt ELx-K, SL & SLSC are non sulfur chemical compounds. The ELx products are elastomer pellets that completely replace elemental sulfur (ES) or sulfur based cross-linkers in stabilizing SBS dispersion in asphalt binder for PMA production. Since 2009, the Elx-SL-crosslinker product delivers environmental and processing benefits, while enhancing PMA's performance, aging resistance, elasticity, and toughness. The ELx-SLSC includes a grafted H2S scavenger to reduce asphalt malodor. The Elx-K application utilizes rubber backbone design to reduce costs of goods.

No Smell, No Gel, No Problems..

Why choose non sulfur based ELx?

The ELx improves the finished product in several ways. When processing High MA, plus spec materials and High Concentrate SBS% products. The lower viscosity ELx finished PMA product reduces plant production time by nature of the quicker reaction process. By adding the ELx with the SBS, the manufacturing process will speed up by at least 3 hours per batch with improved product compatibility and increase storage shelf life. The ELx- linkers will make PMA production risk free - no more hazardous gas generation, no more polymer clean up on the heating coils and processing tanks. Post season polymer vessel clean up will be eliminated.

ELx  Binder Benefits:

  • Increased PMA product storage stability and improved compatibility

  • SBS% loading reduction

  • No gelation - No plant equipment plugging risk.

  • No special equipment required

  • Easy to use - Just add the ELx with the SBS milling

  • No sulfur H2S hazardous creation 

  • Eliminates liquid scavenger addition

  • Lower finished product viscosity

  • Lower storage temperature requirements

  • Improved production batch time

  • Operator proof x linking 

  • Improved transportability and off loading

  • Eliminates postseason PMA vessel and heating coil maintenance

 With all these benefits, ELx addition improves the product,  eliminates the plant and tank clean up costs and catastrophic events are eliminated.

NON Sulfur ELx TESTIMONIALS:

Northeast PMA PG Producer: ELx-SL

The Elx cross liker has been very effective, safe, economical and stable when producing HIMA PG modified grades. Due to weather, a late Fall project shutdown leaving ~200 tons in storage. The plant held the product in storage for 4 months @ 275-300F. In the Spring, the project resumed and remarkably the PG results had not budged at all, it was still in specification. The product was used to continue the project. The ELx is the best cross linker system on the market- Why isn’t everyone using it?

Mid-Continent PMA PG Producer using ELx-MG

Even though the crosslinker is sulfur based, it has exhibited non gelation characteristic’s in production. It can be added along with the polymer without runaway gelation viscosity. This has reduced the production process by 8 hours. It is the only crosslinker that is operator proof!

West Coast PMA PG Producer: ELx-kSL

After some sulfur odor issues, I started using the ELx-SL in 2020. Bob mentioned that a new crosslinker would reduce the product cost without sacrificing performance. I switched from the SL to the kSL and it delivered the same effectiveness as promised.

Mid-Continent Modified Roofing Producer: ELx-SL Plus:

Being a semi-enclosed plant, with engineered controls in place, there was ongoing H2S break through occurring and the alarms were shutting down the plant. During the investigating, the root cause was that the base asphalt H2S increased and was peaking at >3000ppm. The SL Plus has a Scavenger to mitigate the inherent asphalt H2S and the processing generated malodor. After adding the SL Plus, the post engineering control equipment reading was < 3ppm. Problem solved!
