Silane Coupling Agents for Tires

Leading edge additives for the manufacturing of high performance tires.

As rapidly evolving technology and increased global pressure to reduce fuel consumption and emissions impose new demands on tires, we understand your need to manufacture an advanced product that can go the distance. We also know that making a better product often requires going beyond the standard approach. That’s why we combine expertise, vision and scientific data to offer you innovative solutions.


Advanced tire silanes NXT* and NXT Z45: the ingredients for success

In paving the way for the future, we strive to conceive solutions that assist in realizing high-quality products and enhanced manufacturing processes. With NXT* and NXT Z45 silanes, we offer a new level of support that can help you create tires that stand out in the showroom and perform on the road. 


Reduced rolling resistance

With fuel and emission reduction targets being mandated worldwide, it is necessary to improve the rolling resistance of tires in order to meet new standards. Incorporating Momentive’s advanced silanes into the tire tread can lead to greatly improved rolling resistance ratings. As a result, tires can require less energy, and hence cars can consume less fuel to function, without compromising safety. 


Better wet traction

NXT* and NXT Z45 silanes enable the manufacture of tires with the reduced rolling resistance needed for increased fuel efficiency while maintaining wet traction. This critical safety-related benefit can allow vehicles to stop faster and grip the road better, empowering you to further exceed consumer expectations.

 

Desirable testing results

NXT silanes offer design possibilities by helping you to achieve the following effects in rubber compounds:

  • Improved filler dispersion and reduced Payne Effect
  • Increased resilience
  • Lower tan δ values (50 °C to 60 °C)
  • Better dynamic properties at low temperatures (-20 °C to +10 °C)


More efficient manufacturing

Where NXT Z45 is the ultimate performance silane, NXT* silane combines performance benefits with enhanced tire manufacturing process capabilities. Despite high silica loadings in combination with functionalized polymers, NXT silane promotes better dispersion and reduced compound viscosity, for easier processing during compound mixing, milling and extrusion. This can result in numerous benefits, including: 

  • Fewer steps in the compound mixing process
  • An increased tread extrusion rate and reduced rework
  • A smoother tire tread profile
  • A longer shelf life of silica compounds before re-milling is required

 

Momentive’s advanced NXT* silane products

NXT silane is a thiocarboxylate functional silane that has allowed manufactures to develop tires with reduced rolling resistance, while maintaining wet traction. This advanced silane also offers processing benefits for the tire manufacturer that can lead to improved milling consistency, increased extrusion throughput, and less waste when compared to the use of standard sulfur silanes. It can allow easier processing and enhance compound shelf stability when advanced functionalized polymers and high surface area fillers are used.

NXT Z 45 silane is a revolutionary advanced silane that is virtually ethanol-free. This silane can allow manufacturers to dramatically improve the dynamic and physical properties of tires for unprecedented performance regarding rolling resistance, grip and wear resistance.

Carbo NXT silane is available in powder form for processing flexibility. Carbo NXT silane offers tire manufacturers the same opportunities for enhanced tire performance and increased efficiencies as the liquid NXT silane form.
