The Problem We SolveUnlocking the potential in nanotubes

Since 1991:

• Multiple companies types,

same problems

• Micron sized clumps

• Hard to integrate

• Utilized in lower

value applications

• Key to unlock potential is

ability to utilize discrete

tubes

Molecular Rebar® = Dispersible in Rubber

Unprocessed MWCNT in SBR Molecular Rebar™ in SBR

• The MRD masterbatch process produces a product that disperses as individual tubes in a rubber matrix

• This maximizes the reinforcing properties of carbon nanotubes

Managing White SpacesIn filled systems, the weakest phase is the unfilled spaces, “white spaces”.

Crack propagation can occur in unreinforced ‘White Spaces’

MR strengthens the white spaces and act as “molecular rebar” to prevent crack propagation

Uniqueness of Molecular Rebar®

Molecular Rebar® are discrete, high aspect ratio MWCNT with modified surface chemistry

In rubber applications, Molecular Rebar® can:

1. Increase abrasion and cut & chip resistance

2. Increase stiffness, strength

3. Improve thermal and static conductivity

4. Improve matrix to filler interaction through surface functionality

5. Improve bonding to substrates through surface functionality
