Powertrain: Timing Systems and Tensioners

Proven materials and expertise for tensioners that last the life of the vehicle

Stanyl is the material of choice for chain tensioner guides:

• Offers better wear performance than high molecular weight PA66
• Gives highest safety and durability factor, and reduces noise generated by the chain
• Proven in all engines and all models at all major automotive producers including GM, Ford, Chrysler, Toyota, BMW, Mercedes, Porsche and more

Value opportunities from fully plastic guide components
Replacing the aluminum structural support for the guide, reduces weight, lowers system cost and contributes further to noise reduction. Depending on system requirement, single piece, two piece or 2-shot plastic molded parts in Stanyl has already delivered the required performance.

• Excellent fatigue and creep resistance at temperatures encountered in the application
• Combination of oil resistance, long term ageing resistance and high temperature stiffness is unmatched

DSM has expertise to support the development process:

• Understanding the system and knowing what is important and how this affects the loading and performance of the structural parts
• Extensive material data available at high temperatures found in the system
• Modeling experience for translating application requirements into plastic properties, to give the optimum part design for the allowable packaging space
