EPDM
Strong resistance to weather, ozone, water, steam, and many polar chemicals.
Rubber Material Selection Guide
Choose a rubber compound around temperature, chemicals, and sealing performance.
Compare elastomer family, temperature range, fluid compatibility, compression set, abrasion, weather resistance, hardness, flexibility, processing, and cost.
Selection Overview
Start with the complete service environment.
Rubber selection depends on the complete operating environment. A compound that performs well in heat may fail in fuel, ozone, steam, or low temperatures. Buyers should evaluate fluid exposure, pressure, motion, compression, abrasion, weather, hardness, elongation, reinforcement, cleanliness, regulatory requirements, and the manufacturing process used to form the part.
Comparison Criteria
Material families and performance factors to review.
Use consistent technical and sourcing criteria so candidate materials, grades, and suppliers can be compared on the same basis.
Nitrile Rubber
Commonly selected for petroleum oils, fuels, greases, and general industrial sealing.
Silicone Rubber
Broad temperature range, flexibility, electrical insulation, and clean or medical applications.
Neoprene
Balanced weather, flame, moderate oil, and mechanical performance.
Viton and FKM
High-temperature fluoroelastomers used with fuels, oils, and aggressive chemicals.
Natural Rubber
High resilience, tensile strength, abrasion resistance, and dynamic performance.
Polyurethane
Excellent abrasion, tear, load-bearing, and wear performance in many industrial parts.
Compound Variables
Hardness, fillers, plasticizers, reinforcement, color, cure system, and additives.
Specification Details
Provide enough information for an accurate material recommendation.
Fluid Exposure
List oils, fuels, solvents, cleaners, acids, alkalis, water, steam, and concentration.
Temperature Range
Specify continuous, peak, low-temperature, cycling, sterilization, and heat-aging conditions.
Mechanical Service
Define pressure, compression, motion, flexing, abrasion, tear, impact, and fatigue.
Geometry and Tolerance
Include cross-section, sealing surface, dimensional limits, flash, parting line, and finish.
Compliance Needs
State food, medical, potable water, flame, electrical, or industry-specific requirements.
Manufacturing Method
Clarify molding, extrusion, die cutting, calendaring, bonding, overmolding, or fabrication.
Selection Workflow
A practical path from operating conditions to material approval.
Characterize the environment
Document fluids, temperature, pressure, motion, weather, abrasion, and cleaning exposure.
Screen elastomer families
Eliminate materials that fail chemical, thermal, mechanical, or regulatory requirements.
Choose hardness and compound
Balance sealing force, flexibility, wear, reinforcement, color, and processability.
Confirm manufacturing compatibility
Review molding, extrusion, bonding, shrinkage, tolerances, tooling, and finish.
Validate with service testing
Use immersion, compression set, aging, wear, leakage, and dimensional tests as needed.
