Automotive Rubber Powertrain Systems

The need for high performance elastomer's in engine and powertrain systems is on the rise because of the higher engine temperatures, extended warranty periods and the growing need to reduce engine emissions. Datwyler's family of elastomer's used in automotive rubber applications addresses these needs, as well as, an array of other functional applications.

Engine Gaskets and Seals
Engine gaskets and seals used in engine applications require an elastomer that demonstrates great fuel and high temperature stability and Viton® fluoroelastomer is typical the compound of choice for such applications. Products that Columbia produces that use Viton® include: fuel injection seals, fuel pump seals, manifold gaskets, diaphragms and other applications that require custom molded rubber products.
With the trend of engine and powertrain systems pushing sealing materials to their limits, Columbia has responded by developing new materials that are able to meet these strenuous demands and still be cost efficient, allowing us to offer very competitive pricing.

Power Steering Seals
Many of the power steering applications of today use high-pressure hydraulic systems. Seals for these applications include an input shaft seal and inner and outer rack seals. The input shaft seal also called a pinion seal are for shafts with slow oscillating rotation, and they have operating pressures that are 10 to 20 psi.
The outer rack seal and inner rack seal are reciprocating applications and can see pressures up to 1500 psi. Typical rack seals will have plastic PTFE back-up rings to prevent seal lip blowout.
Power Steering Hoses
Power Steering hoses require elastomer's that are able to perform well under a number of different conditions. For example, the elastomer will need to have high tolerances for oil, heat and ozone resistance because of the demanding conditions of transmission and engine systems. It must also be able to withstand high temperatures and have the durability for long term life applications

Head Gaskets
The cylinder head gasket is commonly considered to be the most important seal in the automotive engine. The Multi-Layer Steel (MLS) gasket is know the automotive industries preferred method of sealing between the cylinder head and engine block. In this system, multiple layers of cold-rolled spring grade stainless steel are coated with a thin layer of elastromeric material. This thin layer of elastomer is essential to the structure by providing a sealing action to the metal surface imperfections, while resisting aggressive gases, oils and coolants.

Nitrile (NBR) is an elastomer that is commonly used, however, Fluoroelastomers , more specifically Viton®, is quickly getting attention for its high temperature resistance and its aggressive resistance to fluids such as, fuels, fuel mixtures, coolants, oils and combustion gases.

Transmission Seals
The Automatic Transmission is a complex system combining several different applications, posing a challenge for seal designers. Typically their are two main types of transmission designs: rear wheel drive and front wheel drive, both requiring seals to prevent any leakage. Rear drive designs, for example, typically employ an input seal to prevent leakage of transmission fluid at the interface between the torque converter and the transmission case. Front drive designs also use an output seal to prevent leakage past the output shaft.
Engine Mounts
Engine mounts are rubber to metal bonded components used to isolate vibration, absorb shock and support load. Datwyler's engine mounts are highly durable and heat resistance.
Engine Mounts

Applications in the chassis and underbody systems that call for rubber products includes; shock absorber seals, CV boots and liners, vibration mounts and air springs, all of which contribute to the smooth ride all drivers want. Hoses, cups and boots provide the performance necessary for critical braking and steering systems.

Automotive Rubber Bushings
Auto Rubber Part - In Chassis
Brakes and Modules
Brakes are one of the most critical parts on an automobile and rubber parts used in such applications need to be able to withstand the extreme environmental hot's and colds, as well as the frictional heat produce from everyday braking. Some of the applications Datwyler is currently manufacturing are listed below.

Fuel Systems

Viton® fluoroelastomer is so effective against extremes of heat, chemicals, fuel mixtures,and fuel additives that it has become an essential element for meeting stringent emission requirements. With today's tightening controls on emissions and passenger safety, more demands than ever will be placed on hoses and sealing components used in automotive systems.

Fuel Seal
Stringent automotive emission regulations and increasingly hostile engine compartment environments are making life tough for fuel system seals, diaphragms and gaskets. Only a few specialty elastomer's like Viton® fluoroelastomer can function under such conditions and enable system designers to meet near zero fuel permeation targets.
HVAC - Heating & Cooling Systems
In the early 1990's chlorofluorocarbon (CFC) refrigerant, which is what automotive air conditioning systems relied on, was changed to what is known as R-134a, because of proven harm that CFC's had on the ozone. With this change came complications with the current seals being used. The change to R-134a necessitated the use of a different type of lubrication. The combination of this new lubrication, as well as, higher operating temperatures, made the current types of elastomer's being used for sealing applications obsolete. A change had to be made. Hydrogenated nitrile (HNBR), with its good resistance to such conditions has proven itself useful in such applications and is know the more popular elastomer used in automotive sealing applications.

HVAC & Cooling Systems
Datwyler has the experience and ability to design and manufacture custom seals and sealing devices for both your automotive HVAC and Cooling Systems. Having been involved in the automotive rubber industry for over 30 years, Datwyler has experienced engineers to help in the design process as well as in choosing the correct elastomer for the application.
Electrical Systems

The electrical system is one of the more important aspects in an automobile for both personal comfort and general operations. In order for this system to run smoothly the electrical components must be sealed from outside moister and debris. Datwyler have over 30 years designing and manufacturing compounds for such applications that focus on both durability and functionality.

Automotive Electrical Systems
Headlight Seals
A common problem in a headlight systems is moister seeping through poorly sealed crevasse and entering into the headlight itself, causing a cloudy appearance. To avoid this, custom seals are added around all the wire fixtures and any other applications where two parts are being joined.
