Rubber Materials for Custom Molded Parts

Wayne Rubber provides a wide range of high-performance rubber materials and custom elastomer compounds for custom molded rubber parts used across industrial, automotive, and specialty applications. Selecting the right material is critical to ensuring long-term performance, durability, and cost efficiency.

We work with both common and specialty elastomers including EPDM, silicone, nitrile (NBR), chloroprene (CR), FKM, SBR, HNBR, fluorosilicone, FFKM, urethane, and natural rubber. Through our custom rubber formulation and mixing capabilities, we tailor compounds to meet exact application requirements.

Whether your application requires weather resistance, oil compatibility, high-temperature performance, or chemical resistance, Wayne Rubber can help you select and manufacture the ideal material solution for your gaskets, seals, O-rings, and other critical components.

Temp Range: -65°C to +175°C
Ultra-Specialty Elastomer
Perfluoroelastomer (FFKM)
Used in extreme environments up to 330°C. Exceptional chemical resistance and compression set for critical sealing.
Temp Range: -10°C to +330°C
Specialty Elastomer
AEM
Excellent resistance to hot oils and automotive fluids. Used in seals, gaskets, and hose for under-hood applications.
Temp Range: -40°C to +175°C

How to Choose the Right Rubber Material

Selecting the correct rubber material depends on several key factors, including application environment, performance requirements, and regulatory considerations. Wayne Rubber works closely with customers to align material selection with both product performance and manufacturing efficiency.

1. Temperature Requirements

Consider both continuous and peak temperatures. Silicone and FKM perform best in high-heat environments, while materials like EPDM offer stable performance across a wide temperature range.

2. Chemical Exposure

Exposure to oils, fuels, or harsh chemicals requires specialized materials such as nitrile (NBR) or FKM, commonly used in automotive and industrial sealing applications.

3. Environmental Conditions

Outdoor applications require resistance to UV, ozone, and moisture, making EPDM a strong choice for gaskets and sealing components exposed to the elements.

4. Mechanical Requirements

Applications involving stress, vibration, or repeated motion require materials with strong elasticity and tear resistance, such as natural rubber or SBR. These are commonly used in vibration mounts and bushings.

5. Regulatory Requirements

Food-grade or medical applications may require compliant materials such as silicone, commonly used in food processing and medical applications.

If you’re unsure, Wayne Rubber can evaluate your application and recommend the best material based on performance, environment, and cost considerations.
