PRISM WORLDWIDE
Prism was founded on the principle that
there should be a better use for end-of-
life (ELT) tires.
We are bringing new patented chemistry
and technology to the market that
produces novel polymers that can be
used in a broad range of applications.
Our polymers enable higher value uses
for end-of-life tires and offer a route to
Making Tires More Circular™.

PRISM
WORLDWIDE
Polymers are:
• Domestically produced MADE IN
USA – meets IIJA Buy America
requirements
• Sustainable
Used in/as:
• asphalt for roads and roofs,
• thermoplastic elastomers,
• additives for thermoset materials
5. 5
VIATEC TECHNICAL POINTS:
• ViaTec™ is made exclusively in USA:
• High solubility in asphalt ~99%
• Stiffens asphalt (higher softening point, lower penetration values)
• Improves PG grade, elasticity (can improve both upper and lower
end)
• Easy to incorporate -- ~30 minutes mixing at 300-350˚F to become
fully homogenous – (dependent on asphalt, equipment, etc.)
• Delivered in supersacks
• Dry storage stability
• Includes antioxidants, antiozonates to improve aging characteristics
• Favorable LCA compared to typical synthetic polymers
6. Additive Equipment and
Procedures
1. Add the required amount to base asphalt that
has been heated to a minimum 310 to 325°F.
2. Begin mixing using a mixer head like the one
shown below at a rate of 500-1000 RPM for
~30 minutes. Check for homogeneity using
paint stirrer or spatula. If necessary, continue
mixing until homogenous. If needed,
temperature and speed can be increased to
achieve a smooth blend.
