> Silicone Rubber Extrusions CS Rubber Products Co.,ltd is a professional manufacturer of silicone rubber extrusions, specializing in standard and custom silicone extrusion profiles for industrial sealing, insulation, protection, cushioning, and connection applications.
Our capabilities cover simple cords and tubing as well as complex profiled sections and composite constructions. We develop extruded silicone products according to customer drawings, samples, CAD files, or application requirements — with suitable materials, hardness, colors, dimensions, and performance characteristics selected for the intended use.
CS Rubber Products Co.,ltd manufactures a wide range of silicone profiles for different sealing, insulation, protection, and connection requirements. Depending on the application, our extruded silicone products can be supplied as solid, hollow, cellular, reinforced, or specially shaped profiles.
Manufactured with controlled dimensions and consistent wall thickness for fluid transfer, insulation, protection, and equipment connections. Tube diameter, wall thickness, hardness, color, and length can be customized according to drawings or specifications.
Custom silicone seal strips are available in a wide range of cross-sectional shapes. These silicone extrusion profiles can be supplied in continuous coils or fixed lengths, and can be combined with adhesive backing or other secondary processing.
A lightweight cellular structure with flexibility, resilience, and sealing capability. Ideal where cushioning, gap filling, thermal insulation, or low-pressure sealing is required. Density, hardness, profile dimensions, and cross-sectional design can be customized.
A dense and resilient structure with good flexibility, compression resistance, and dimensional stability. Different diameters, hardnesses, colors, and lengths are available for sealing, cushioning, protection, and gasket applications.
Not every application can be solved with a standard profile. Our custom silicone extrusion service is designed for OEM customers that require a specific cross-section, material performance, dimensional requirement, or installation method.
Customers can provide engineering drawings, CAD files, physical samples, or profile sketches. Based on the information provided, our engineering team evaluates the profile geometry and production requirements and develops the appropriate tooling and extrusion solution.

| Composite construction | Dual-hardness, dual-color, metal inserts, fabric reinforcement, silicone-plastic combinations | Used for integrated sealing, reinforcement, insulation, or other functions |
| Post-processing | Precision cutting, adhesive backing, corner joining, bonding, vulcanized splicing, punching, die cutting, flaring, edge sealing, and post-curing | Selected according to assembly and installation requirements |
| Packaging | Coils, bags, cartons, labels, and kitting | Arranged according to customer requirements |
Our OEM service covers the complete process from profile development to finished production. After receiving the drawing or sample, we review the required cross-section, material, hardness, dimensions, tolerances, and application conditions.
A suitable extrusion die is then developed for the required profile. During extruding silicone, the compound is continuously formed through the die and vulcanized to establish the required elasticity and dimensional stability.
Depending on the final application, additional operations such as cutting, adhesive backing, corner joining, bonding, splicing, punching, or post-curing can be performed.
This approach allows us to produce custom silicone extrusions that are ready for integration into the customer's equipment or assembly — rather than supplying only a basic extruded profile.
Silicone rubber extrusions are widely used in industries where reliable sealing, flexibility, insulation, temperature resistance, or environmental durability is required.
Silicone extrusion products can be used in food and beverage processing equipment for sealing, tubing, insulation, and protective applications where appropriate material grades are required.
Extruded silicone products are suitable for various medical and healthcare equipment applications requiring controlled dimensions, flexibility, cleanliness, and specialized silicone materials.
Silicone rubber extrusion products can provide electrical insulation, environmental sealing, protection, and thermal management for electrical and electronic assemblies.
Custom silicone extrusion profiles are used in machinery, equipment enclosures, access panels, doors, piping connections, and other components requiring flexible sealing or protection.
Silicone sealing profiles can be used in building systems, HVAC equipment, enclosures, doors, windows, and other installations where weather resistance, flexibility, and long-term sealing performance are important.
Silicone rubber extrusions can also be developed for battery systems, charging equipment, electrical components, and other new energy applications requiring insulation, sealing, protection, or thermal management.
CS Rubber Products Co.,ltd combines silicone extrusion manufacturing with in-house engineering and secondary processing capabilities. By controlling key production stages internally, we can coordinate material selection, tooling, extrusion, vulcanization, finishing, inspection, and delivery more efficiently.
Hardness, color, dimensions, cross-sectional geometry, and performance characteristics can be developed to suit your requirements.
Silicone formulations are available for industrial, food-grade, medical, and specialized performance requirements.
We assist with material selection, profile design, structural optimization, mold development, and production planning.
Options include flame-retardant, conductive, thermally conductive, insulating, high-temperature, low-temperature, oil-resistant, solvent-resistant, halogen-free.
Products can be supplied with cutting, adhesive backing, corner joining, bonding, splicing, punching, die cutting, flaring, edge sealing, or post-curing.
Multiple extrusion and vulcanization production lines support both custom development and repeat production.
CS Rubber provides silicone rubber extrusion solutions for manufacturers that need profiles developed to their own drawings, samples, or technical specifications.
Whether you need silicone tubing, sealing strips, foam profiles, solid cords, or a more complex custom cross-section, we can support the project from tooling development through extrusion, vulcanization, secondary processing, inspection, and final supply.
As one of the experienced silicone extrusion manufacturers and silicone rubber extrusion manufacturers, CS Rubber focuses on practical profile design, consistent production, and reliable supply for OEM and industrial applications.
