Automotive Silane Coupling Agents for Tires

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 tire development, 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 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 significantly improve rolling resistance ratings. As a result, automobiles can require less energy to move, and hence consume less fuel 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 not impacting wet traction. This critical safety-related feature allows vehicles to stop faster and grip the road better, empowering you to further exceed consumer expectations.


Desirable testing results

NXT silanes offer design possibilities with key features and typical benefits that include:

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


More efficient manufacturing

Where NXT Z45 is our ultimate performance silane, NXT* silane combines performance benefits with tire manufacturing process enhancement 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  enables 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 allows manufactures to develop tires with reduced rolling resistance while maintaining wet traction. This advanced silane also offers processing benefits for the tire manufacturer that lead to improved milling consistency, increased extrusion throughput, and less waste when compared to the use of standard sulfur silanes. It allows easier processing and enhance compound shelf stability when advanced functionalized polymers and high surface area fillers are used.

NXT Z 45 silane is an advanced silane that is virtually ethanol-free. This silane allows manufacturers to dramatically improve the dynamic and physical properties of tires, including an outstanding combination of 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 to enhance tire performance and increase manufacturing efficiencies as the liquid NXT silane form.
