Material Guide

Start with the working conditions

Material names are only the starting point. Share the exact media, temperature, pressure, motion, groove, hardness and required standards so the compound and grade can be reviewed for your application.

Core Material Families

Frequently discussed elastomers

These families cover many industrial RFQs. Final suitability depends on the exact compound formulation and service conditions.

Current product range Project review required

NBR

Nitrile Rubber

Current range

Key strengths: Oil resistance, wear performance and economical industrial sealing.
Watch points: Ozone, outdoor weathering and some polar fluids require review.
Common review areas: Hydraulic, pneumatic, machinery, pumps and valves.

HNBR

Hydrogenated Nitrile

Current range

Key strengths: Improved heat, oil, wear and mechanical performance over standard NBR.
Watch points: Low-temperature performance and chemical compatibility are grade-specific.
Common review areas: Automotive, oilfield, hydraulic and demanding dynamic seals.

FKM

Fluoroelastomer

Current range

Key strengths: Heat resistance and compatibility with many fuels, oils and chemicals.
Watch points: Steam, hot water and low-temperature needs require careful grade selection.
Common review areas: Fuel systems, chemical equipment and high-temperature seals.

EPDM

Ethylene Propylene Rubber

Current range

Key strengths: Water, steam, weathering, ozone and outdoor performance.
Watch points: Generally unsuitable for petroleum oils and hydrocarbon fuels.
Common review areas: Water treatment, HVAC, plumbing and outdoor equipment.

VMQ

Silicone Rubber

Current range

Key strengths: Wide temperature range, flexibility, color options and clean applications.
Watch points: Tear, abrasion and demanding dynamic service need application review.
Common review areas: Food equipment, appliances, electronics and static seals.

FVMQ

Fluorosilicone Rubber

Project review

Key strengths: Low-temperature flexibility with improved fuel and oil resistance.
Watch points: Higher cost and lower mechanical strength than many general elastomers.
Common review areas: Specialty fuel, aerospace-style and low-temperature applications.

Chloroprene Rubber

Current range

Key strengths: Weathering, ozone, moderate oil exposure and flame performance.
Watch points: Not the first choice for broad fuel resistance or very high temperatures.
Common review areas: Outdoor equipment, industrial profiles and general machinery.

Specialty Options

Beyond the standard rubber families

These options broaden the engineering discussion. They do not imply stock, certification or production capability; grade, MOQ, tooling and sourcing must be confirmed for each project.

FFKM

Strength: Broad chemical and high-temperature performance.

Review: Premium, compound-specific option for severe process service.

FEPM / Aflas type

Strength: Steam, amines, acids and bases in selected grades.

Review: Low-temperature and exact media limits.

ACM

Strength: Hot oil and automotive-fluid performance.

Review: Water, low temperature and broad chemical limits.

AEM

Strength: Heat, oil and weathering balance.

Review: Fuels, acids and bases are grade-dependent.

IIR / Butyl

Strength: Low gas permeability and selected chemical resistance.

Review: Petroleum oil and fuel exposure.

AU / EU / TPU

Strength: Wear, tear and extrusion resistance.

Review: Hydrolysis, heat and chemical compatibility by chemistry.

NR / SBR

Strength: Resilience, abrasion performance and economy.

Review: Oil, fuel, ozone and outdoor weathering.

PTFE Non-elastomer

Strength: Low friction and broad chemical resistance.

Review: No elastic recovery; energizer and seal design may be required.

Engineering note

Temperature ranges and chemical resistance vary by formulation, hardness, cure system and exposure. This guide supports RFQ discussion and is not a final compatibility recommendation.
