Leader in Advanced Material Technologies

Elastomer and ThermoplasticComponents and Assemblies For

Motorized Vehicles

Minnesota Rubber and Plastics

is one of the most experienced

manufacturers of elastomer and

thermoplastic components and

assemblies supplying the sealing

needs of the transportation

industries since 1945. For both

static and dynamic applications,

our expertise in engineering design,

materials R&D, manufacturing and

assembly has made us the preferred

supplier for OEM’s around the globe.

We know the demands of the transportation

industries require a deep knowledge and

experience with end market applications. It

also requires component design and materials knowledge

for products that function without failure in demanding

environments.

Specialized Applications Today increased regulations and standards, along with more

demanding operating environments, challenge materials and

designs with aggressive fl uids, fuels and longer warranty

periods.

■ With passenger cars our high performance plastic capabilities

replace more expensive and heavier metal components.

■ In heavy duty trucks our materials

expertise provides sealing solutions

for reduced weight, noise and

increased safety.

■ For agriculture and

construction equipment

our component designs

and assemblies offer

cost-effective

alternatives.

■ Our rail track and rolling

stock products provide

excellent vibration &

insulation qualities for

high speed rail systems

in Europe and Asia.

Technology BasedMinnesota Rubber and Plastics

broad range of high performance

elastomers, fl uoroelastomers

and thermoplastics, such as PEEK,

Aurum®, Torlon® or Ultem® are

engineered to meet demanding

sealing applications by providing

long-term protection against wear,

high temperatures and corrosive

operating environments.

Our technical design and

materials groups can help

you solve critical issues so you can

manufacture quality products cost-effectively.

Global ReachToday most companies utilize global sourcing as a key

component of their procurement strategy to expand or develop

new markets as they look to control costs.

At Minnesota Rubber and Plastics we leverage our experience

with your requirements across our North American, Asian and

European manufacturing and resource base to design, develop,

manufacture and deliver precision components and assemblies.

What’s more, our 6 manufacturing facilities are complemented

by our global warehousing and logistics operations.

Commitment To QualityAll Minnesota Rubber and Plastics design, development

and production facilities operate under corporate wide

quality systems including ISO/TS 16949 and ISO 9000.

Our facilities also operate under a corporate wide

Environmental Management System registered to the

International Standards Organization series ISO 14001.

Committed To Innovation While Providing Solutions

Expanding Markets – Decreasing CostsIn our industry we are uniquely positioned to offer both

rubber and plastic combination parts. This allows us to

provide greater development and production effi ciencies,

thereby reducing development time and costs.

From prototyping to fi nal production, our state-of-the-art

design engineering services provide timely answers to

diffi cult design issues. Our CAD/CAM and FEA systems

allow us to offer design alternatives quickly while our tool

development and secondary press operations are second

to none. Finally, prior to committing to production, our

prototyping services provide production quality sample

parts for fi nal testing.

Materials R&DWe have an advantage over many rubber and plastics

manufacturers because we place a great deal of emphasis

on research and development. Our technical support staff

provides the resources to design, formulate, develop and

test materials and parts.

With elastomers we are known for our bonding and over

molding capabilities on metal substrates or on high

performance plastics. We use proprietary

technologies with both chemical and

mechanical bonding to ensure

a durable fi nished part while

minimizing production costs.

Our test cell for PEEK transmission

seal rings is an example of our materials

technologies with high performance plastics.

This semi-crystalline polymer is used

to replace metal components in many

automotive and heavy vehicle

transmissions. However, until

we developed a PEEK test cell, to

document critical wear application

data, none was available to industry.

Providing Industry SolutionsAt Minnesota Rubber and Plastics our goal is to provide

OEM’s, tier one and tier two customer’s with the problem

solving solutions critical for their applications. For over 65

years our commitment and dedication to the transportation

industries has provided the needed components and assem-

blies, while meeting pricing and delivery requirements.

Whatever your elastomer and thermoplastic design challenge

we’re here to make your application a reality. By working

directly with you and exploring new design and material

technologies, you can be certain our recommendations and

commitment to your product requirements will meet your

expectations.
