Explore Applications
Automotive Engine Cover
Delivering a more pleasant driving experience is key. We crafted our wide range of SPECFLEX™ flexible foam systems to be used in engine cover encapsulation and NVH applications broadly to help boost climate control, comfort and acoustics in your vehicle’s interior, exterior and powertrain.
Engine Cover Solutions
SILASTIC™ Silicone Elastomer Custom Compound
Design custom elastomers that meet your unique needs and resolve your processing challenges.
SPECFLEX™ Custom Systems
Dow offers a wide range of flexible foam systems commonly used in powertrain solutions like engine cover encapsulation.
Automotive Engine Materials
Drivers may be more concerned with point A to point B, but we’re all about the journey. And that means engineering materials that help improve the reliability of every engine component from hoses, seals and gaskets to grommets, O-rings, engine mounts, intake manifolds and boots.
What adhesive, sealant, and silicone rubber solutions might work for your project?
Automotive Hoses and Belts
Your hoses and belts are constantly working to keep your vehicles moving. Let Dow’s advanced EPDM technology work hard for them – and improve your sustainability profile at the same time.
Our silicone-powered rubber solutions are uniquely formulated with a reduced environmental footprint and help ensure essential components like turbocharger hoses provide premium oil/fuel permeation resistance and withstand wear-and-tear in even the most extreme conditions.

Automotive Filters
Not all automotive filters are created equal. Let us help you explore the materials that will increase the capacity and performance of your cabin, fuel, oil or air filters during assembly. Whether for passenger vehicles or heavy-duty industrial equipment, our polyurethane-based adhesives and sealants and mold release compounds can increase resistance to chemicals, compression and temperature.
Resources
Can smart science drive design innovation?
From coolant and heater hoses to engine seals and gaskets, Dow’s advanced silicone materials can support these applications for increased component durability and powertrain reliability.
Silicone Rubber
Silicone Rubber: Fluorosilicone Rubber (FSR) for heat and fuel resistance.
Dow offers engineered resins, elastomers, foams, and adhesives for under-hood applications, including silicone and polyurethane materials for hoses, belts, seals, gaskets, engine covers, and other powertrain components to boost durability, chemical and temperature resistance, and overall performance.
Engine cover encapsulation uses Dow’s flexible polyurethane foam systems (e.g., SPECFLEX™) to form a protective, acoustical layer over engine components. These foams improve comfort, reduce noise, vibration, and harshness, and help manage heat within the engine bay.
Materials like Dow’s polyurethane acoustic foams (e.g., BETAFOAM™) and elastomeric resins are used to reduce noise, vibration, and harshness in engine bays. These foams fill cavities and damp vibrations, providing quieter, more comfortable vehicle performance.
Dow’s EPDM offers tough, versatile performance for hoses and belts under varied conditions. Silicone rubber solutions provide enhanced resistance to heat, oil, and fuel permeation in extreme under-hood environments, improving durability where high thermal and chemical resistance are needed.
Automotive filters are assembled using Dow’s polyurethane-based adhesives and sealants, which enhance chemical and temperature resistance during filter assembly for cabin, fuel, oil, and air filtration applications.
