Reliable underground pipe systems are essential for modern infrastructure. Whether transporting water, managing wastewater, or supporting drainage networks, these systems depend on secure, leak-free connections to perform effectively over long service lives. At the heart of these connections are pipe seals, which help prevent leaks, maintain system integrity, and reduce the need for costly maintenance and repairs.
Thermoplastic elastomers (TPEs) combine the flexibility and elasticity associated with rubber with the processing advantages of thermoplastics. Unlike traditional rubber compounds, TPEs do not require a curing or vulcanization step, helping manufacturers simplify production and improve efficiency.
Why Use TPE for Pipe Seal Manufacturing?
Manufacturers of pipe seals are under increasing pressure to improve productivity while maintaining consistent product quality. Material selection can have a significant impact on both manufacturing efficiency and final product performance.
EVOPRENE TPE compounds were designed to run on conventional processing equipment without depositing chemical residue on tooling during processing. Because no curing process is required, manufacturers may significantly reduce cycle times, helping optimize production rates and increase output.
Benefits of EVOPRENE TPE Compounds for Pipe Seals
No curing process required.
Reduced manufacturing cycle times compared with rubber.
Clean processing with minimal tool residue.
Compatible with conventional processing equipment.
Designed specifically for sealing applications.
Available in grades tested to recognized industry standards.
What Performance Properties Are Important for Underground Pipe Seals?
Pipe seals must maintain their sealing performance while exposed to moisture, soil conditions, environmental aging, and long service lifetimes. Material properties such as flexibility, resilience, compression set, and ozone resistance are important factors when evaluating sealing materials.
EVOPRENE TPE grades developed for pipe seal applications offer a combination of mechanical performance and durability. Ozone resistance helps protect seals from cracking and degradation, while good compression set performance helps maintain sealing force over time.
One example is EVOPRENE G 6260 Black:
Hardness: 60 IRHD
Compression set: 30% at 70°C
Tensile strength: 6.6 MPa
Elongation at break: 579%
Specific gravity: 0.97
Ozone resistance (ISO 1431-1): No cracks observed during testing.
These characteristics make EVOPRENE TPE compounds well suited for sealing applications that require long-term reliability and durability.
Where Are EVOPRENE Pipe Seal Compounds Used?
EVOPRENE TPE compounds can be used in a variety of underground pipe sealing applications, including:
Underground drainage systems.
Sewer pipe connections.
Stormwater management systems.
Municipal utility infrastructure.
Wastewater networks.
Non-pressure pipe assemblies.
By providing a secure connection between pipes, seals help prevent leakage, maintain system performance, and reduce the risk of costly repairs or infrastructure failures.
What Standards Are Relevant for Pipe Seal Applications?
Infrastructure products often need to meet recognized performance standards and certification requirements. Certain EVOPRENE grades have been tested to standards relevant to underground pipe sealing systems.
These include:
BS EN ISO 681-2, the international standard covering elastomeric seals for underground drainage and sewerage pipeline applications.
KOMO certification with compliance to BRL 2020-1 requirements.
Testing to recognized standards helps manufacturers evaluate material suitability and support specification requirements for infrastructure projects.
Frequently Asked Questions
What are the advantages of TPE compounds for pipe seals?
TPE compounds combine elastomeric performance with efficient thermoplastic processing. Compared with materials that require curing, TPEs can help reduce manufacturing complexity and shorten production cycles.
Why is ozone resistance important in pipe seals?
Ozone can cause cracking and degradation in some elastomeric materials over time. Ozone-resistant compounds help maintain seal integrity and long-term performance in demanding environments. Certain EVOPRENE grades demonstrated no cracking when tested according to ISO 1431-1.
Can EVOPRENE compounds be processed on conventional equipment?
Yes. EVOPRENE TPE compounds were designed to run on conventional processing machinery while minimizing chemical residue buildup on tooling
Which standards have EVOPRENE pipe seal compounds been tested to?
Certain grades have been tested to BS EN ISO 681-2 and are available with KOMO BRL 2020-1 compliance.
