EPDM Sealing Manufacturers

Jinjiang Yunli Technology Co., Ltd. manufactures a variety of high-quality EPDM Sponge Seals. As a synthetic rubber, EPDM is highly durable, watertight, and offers excellent compression set resistance, making it ideal for creating reliable seals in numerous industrial applications. We produce seals from EPDM material in pre-shaped gaskets, plain or adhesive-backed strips, and washers, ensuring this versatile material can be adapted to any profile.

The Characteristics of an EPDM Sponge / Rubber Seal
EPDM seal material is a closed-cell sponge rubber with outstanding mechanical and chemical properties, making EPDM seals ideal for use in the chemical, electrical, and automotive industries.

Weather Resistance: EPDM rubber is resistant to ozone, UV light, and harsh weather conditions, perfect for outdoor applications.

Chemical Resistance: EPDM seals offer good resistance to acids, bases, and other chemicals, suitable for chemical processing plants.

High Heat Tolerance: Withstands high temperatures and remains durable in low temperatures, making it reliable for use in environments ranging from industrial freezers to high-temperature settings.

Good Compression Set Resistance: EPDM Sponge Seals return to their original shape after compression, ideal for seals, gaskets, and cushioning.

Sound and Vibration Insulation: Absorbs sound and vibration, providing cushioning and reducing noise in automotive and industrial machinery.

Water Resistant: The closed-cell structure is perfect for creating leak-proof seals.

Excellent Elasticity: Easy to install due to its flexibility and elasticity.

Thanks to these properties, EPDM is a versatile and durable material, widely used in automotive, electronic, and construction sectors for jointing, glazing seals, closure seals, and shock absorption.

EPDM Rubber Seal FAQs


What is an EPDM Rubber Seal?
EPDM is a synthetic rubber known for its excellent chemical and mechanical properties, making it suitable for gaskets and sealing across various industries. EPDM seals are durable, insulating, airtight, and watertight.

What can EPDM Sealing be used for?
EPDM gaskets are commonly used as flange gaskets to seal gaps between pipes or components. They are widely applied in automotive, electrical, construction, water, and chemical industries due to their resistance and insulation properties.

What are the main features of EPDM Sealing?
Key features include:

Water and chemical resistance

High durability and abrasion resistance

Performance in extreme temperatures

Flexibility and good compression set resistance

Insulation against heat, noise, vibration, and electrical currents

Weather resistance, suitable for outdoor use

What grades of thickness are available for our EPDM Seals?
We manufacture EPDM seals in standard thicknesses including 1mm, 1.5mm, 2mm, 3mm, 4mm, 5mm, 6mm, 10mm, 12mm, 15mm, 20mm, 25mm, and 30mm, and can produce custom thicknesses as needed.

Is EPDM Sealing environmentally friendly?
As a synthetic rubber derived from petrochemicals, EPDM is not biodegradable. However, its high durability reduces the need for frequent replacement, minimizing waste. Using EPDM seals can also prevent chemical leaks, contributing to safer and more sustainable operations.
