This rubber extrusion method is particularly beneficial for producing long, flexible rubber seals, automotive weatherstrips, and industrial gaskets.

The process is enhanced using co-extrusion techniques, where multiple materials are extruded together to achieve specific performance characteristics, such as improved UV resistance or color differentiation. Hot feed and cold feed extrusion techniques are also used, with hot feed offering faster processing times and cold feed ensuring better dimensional stability.

Compression Molding

Compression molding involves placing pre-measured EPDM rubber into a heated mold cavity,andthen applying high pressure to shape the rubber into the desired form. This process is particularly useful for producing high-durability, custom-molded EPDM profiles, including seals and gaskets with complex geometries.

The primary advantage of compression molding is its ability to maintain excellent mechanical properties, such as high tensile strength, low compression set, and superior weatherproof durability. Vulcanization during this process enhances the rubber’s resistance to extreme temperatures and chemicals.

Calendering

Calendering is a process in which EPDM rubber is passed through a series of rollers to create sheets or thin rubber strips with precise thickness and surface finish. This method is commonly used for manufacturing EPDM sheets, industrial-grade rubber strips, and adhesive-backed rubber components.

The primary benefit of calendering is its ability to produce uniform thickness and excellent surface finish, making it ideal for applications requiring flat, flexible polymer structures. This process also improves the rubber’s impact resistance and moisture resistance.

Solution Polymerization

Solution polymerization is a chemical process used to produce high-quality EPDM rubber by polymerizing ethylene, propylene, and diene monomers in a solvent medium. This process allows for better control over the molecular structure of the rubber, resulting in enhanced properties such as UV resistance, ozone resistance, and excellent insulation properties.

The rubber produced through this method is used in high-performance applications, including flame-retardant options for electrical insulation and non-conductive rubber components for automotive sealing.

Injection Molding

Injection molding is a high-precision manufacturing process that involves injecting molten EPDM rubber into a mold under high pressure. This technique is widely used for producing complex rubber parts, including T-section rubber profiles, edge trim seals, and automotive weatherstrips.

Are There Any Disadvantages of Rubber EPDM Profiles?

Yes, there are a few disadvantages of rubber EPDM profiles, including limited resistance to petroleum-based oils, lower tensile strength compared to some elastomers, and potential shrinkage over time. While EPDM is highly durable and versatile, these factors affect its performance in certain applications.

The following are the disadvantages of rubber EPDM profiles:

Limited Oil and Fuel Resistance: EPDM profiles are not suitable for applications involving direct contact with petroleum-based oils, fuels, or solvents. Unlike materials such as nitrile rubber, EPDM degrades when exposed to these substances, making it unsuitable for fuel line seals or industrial oil-resistant applications.
Lower Tensile Strength: Compared to other elastomers like silicone or natural rubber, EPDM has a lower tensile strength, which means it is not ideal for applications requiring high mechanical stress or heavy load-bearing capacities. This limitation affects its performance in industrial environments where extreme pressure or tension is a factor.
Potential Shrinkage Over Time: EPDM rubber experiences slight shrinkage over long periods, especially under continuous exposure to heat and UV radiation. This shrinkage leads to reduced sealing efficiency and requires periodic adjustments or replacements in applications like automotive weatherstripping and window seals.
Vulnerability to High Temperatures: While EPDM has good temperature stability, extreme heat exposure beyond its operational limits (above 150°C) causes it to lose elasticity and degrade faster. For applications requiring heat resistance above this threshold, materials like silicone are a better choice.
Not Suitable for High-Pressure Applications: Due to its flexible and soft nature, EPDM is not the best choice for applications requiring extreme pressure resistance. In such cases, harder rubber materials or reinforced elastomers are preferred to prevent deformation and ensure long-term performance.

Why Use Rubber EPDM Profiles?
