PVC Compounds & Custom Polymers for Industrial Seals & Gaskets

Why Material Selection Is Critical in Seal & Gasket Manufacturing

From flexible PVC and thermoplastic elastomers to high-temperature engineering polymers, our materials cover the full range of durometer, chemical compatibility, and processing requirements that seal and gasket manufacturers demand.

Seals and gaskets serve as critical barriers against fluid, gas, and pressure loss in virtually every industry. A material failure in a sealing application can result in equipment damage, environmental contamination, production downtime, and safety hazards. Selecting the right compound is essential for reliable, long-term sealing performance. Our AuroraFlex™, AuroraGuard™, and AuroraTec™ product lines offer the flexibility, thermal stability, and chemical resistance essential for reliable sealing performance.

Chemical Degradation Risks: Exposure to oils, solvents, fuels, and corrosive chemicals causes material swelling, hardening, and loss of sealing integrity in compounds not engineered for chemical resistance
Thermal Cycling Failures: Extreme temperatures and repeated thermal cycling cause deformation, cracking, and compression set in materials that lack adequate thermal stability
Compression Set & Flexibility Loss: Seals that cannot maintain elasticity under sustained mechanical pressure lose their ability to create effective barriers, leading to leaks and system failures
Regulatory Compliance: Meeting REACH, OSHA, ISO, ASTM, FDA, and NSF standards is essential for seals and gaskets used in food processing, automotive, aerospace, and energy applications

Industries & Applications That Rely on High-Performance Materials

Automotive Seals & Gaskets

Automotive sealing applications demand materials that withstand engine heat, chemical exposure to fuels and lubricants, and continuous vibration.

AuroraGuard™ SBS and SEBS compounds utilize multiple TPE chemistries to deliver high-performance durability with easy processing for door seals, window weatherstripping, and glass reveals. These compounds are available in clear to low-gloss black formulations with hundreds of metallic body match color approvals in both molding and extrusion grades.

AuroraGuard™ CPE (chlorinated polyethylene) alloys provide an economical solution with excellent resistance to oils and chemicals, improved thermal properties, flame retardancy, and dimensional stability for under-hood gasket and sealing applications.

Industrial Manufacturing Seals & Equipment Gaskets

Industrial machinery, hydraulic systems, and processing equipment require seals and gaskets that resist aggressive chemicals, abrasion, and sustained mechanical compression.

AuroraFlex™ flexible PVC compounds provide cost-effective sealing solutions available from 35A to 95A Shore A durometer with specific gravities ranging from 1.15 to 1.65, engineered for the chemical exposure and compression set resistance that industrial environments demand.

AuroraFlex SL delivers high-abrasion resistance with excellent processing properties for longer-lasting seals with no tearing, ideal for equipment gaskets, pipeline seals, and industrial machinery sealing applications that face constant mechanical wear.

Aerospace Seals & Gaskets

Aerospace sealing applications require materials that combine lightweight performance with extreme temperature resistance, chemical compatibility, and regulatory compliance.

AuroraGuard™ PEI (polyetherimide) compounds are inherently flame resistant with continuous use capability up to 340°F (170°C), providing high mechanical strength for cabin pressure seals, engine compartment gaskets, and fuel system sealing where fire safety and low smoke emissions are critical.

AuroraFlex™ TPE compounds offer excellent resilience and recovery properties for aerospace seals, gaskets, and grommets that experience repeated compression and flexing during flight operations. Most formulations are 100% recyclable and RoHS compliant.

Oil & Gas and Energy System Seals

Oil and gas pipeline systems, pressure vessels, and energy infrastructure require seals and gaskets engineered for extreme pressure, harsh chemicals, and wide temperature fluctuations.

AuroraTec™ PC/PBT compounds offer excellent chemical resistance, high impact strength, and heat resistance, making them suitable for outdoor connector and valve sealing applications in harsh energy environments.

AuroraTec™ TPU composites with fiberglass reinforcement deliver excellent stiffness and mechanical strength while maintaining abrasion, chemical, and oil/grease resistance with improved heat resistance for demanding energy infrastructure sealing applications.

HVAC, Plumbing & Water Management Seals

HVAC duct systems, plumbing infrastructure, and water management equipment require seals that maintain integrity across temperature extremes while resisting moisture and cleaning chemicals.

AuroraGuard™ CPVC compounds provide high-heat performance with low-smoke zero-halogen and flame-retardant properties ideal for sealing applications requiring elevated temperature performance and fire safety.

AuroraGuard™ TPO compounds are used in flame-retardant sealing applications for HVAC systems and can be color matched with UV additives to pass OEM accelerated weathering and two-year outdoor weathering tests for exterior equipment sealing.

FAQs

What materials are best for industrial seals and gaskets?

The best materials depend on your specific application requirements. For flexible sealing applications requiring chemical resistance and compression set recovery, AuroraFlex™ flexible PVC and TPE compounds offer excellent performance across a wide durometer range. For high-temperature environments, AuroraGuard™ PEI compounds provide continuous use capability up to 340°F (170°C). For chemical exposure applications, AuroraGuard™ CPE alloys and AuroraTec™ PC/PBT compounds deliver outstanding chemical resistance. Our technical team can help you select the optimal material based on your temperature, chemical, and compression requirements.

How do custom polymer formulations improve gasket performance?

Custom formulations allow manufacturers to optimize materials for specific operating conditions rather than relying on generic compounds. By engineering the exact durometer, chemical resistance package, temperature range, and processing characteristics your application requires, custom formulations deliver better sealing performance, longer service life, reduced compression set, and fewer field failures compared to off-the-shelf materials.

What materials are best for high-temperature sealing applications?

For high-temperature sealing, AuroraGuard™ PEI (polyetherimide) compounds offer continuous use capability up to 340°F (170°C) with inherent flame resistance and excellent mechanical strength. AuroraGuard™ CPVC compounds provide high-heat performance with flame-retardant properties for elevated temperature environments. Glass-fiber reinforced AuroraTec™ PC/PBT extends heat resistance while adding mechanical strength for demanding high-temperature sealing applications.

How does chemical resistance affect seal and gasket performance?

Chemical resistance is critical for seals and gaskets exposed to oils, fuels, solvents, cleaning agents, and process chemicals. Without adequate chemical resistance, materials swell, harden, crack, or dissolve, causing seal failure and system leaks. Aurora compounds are formulated for specific chemical environments to maintain flexibility, dimensional stability, and sealing integrity throughout the seal’s service life.

Are Aurora’s sealing materials compliant with industry standards?

Yes, Aurora offers sealing materials that comply with a wide range of industry standards including REACH, OSHA, ISO, ASTM, FDA, and NSF requirements. For food processing applications, we offer FDA-compliant and NSF-certified grades. For automotive and aerospace applications, our materials meet applicable safety and performance specifications. Our technical team can help identify the specific compliance requirements for your application.
