Industrial product assembly often faces challenges such as water seepage and dust ingress, vibration and abnormal noise of equipment, slipping and displacement of contact surfaces, and repeated compression failure of gaskets. Ordinary gaskets are made of a single material, which can hardly meet multiple requirements of anti-slip, sealing and cushioning at the same time. Separate procurement of various types will extend the supply cycle and increase docking costs. Mismatched gasket selection easily leads to dust leakage, shifting and abnormal noise, and rework will delay project progress.

Zhongke Foam has been engaged in foam die-cutting processing for many years. Its gasket products fall into two main series: silicone rubber series and foam series. Each series includes solid type and foam type, which can be matched as needed to solve anti-slip, sealing and cushioning requirements in one stop. The products support supporting services for electronics, new energy, industrial control equipment, home appliances, outdoor cabinets and many other industries. We provide full-process coordination including drawing evaluation, sample making and mass delivery, and flexibly support small-batch trial production and large-volume mass production.

I. Silicone Rubber Series: Solid Type & Foam Type

Silicone rubber substrates feature excellent resistance to high and low temperatures, ozone and water sealing performance. They are divided into solid type and foam type according to internal structures, with obvious differences in applicable working conditions.

Solid silicone rubber pads have no internal pores and a dense texture. They deliver high compressive strength, good wear resistance and outstanding waterproof sealing performance. They are suitable for high-pressure sealing, wear-resistant anti-slip and oil barrier scenarios. The downside is relatively high hardness with limited shock absorption capacity. They are widely used for fixed sealing rings, wear-resistant foot pads for equipment and waterproof mouldings.

Foam silicone rubber pads (silicone foam rubber pads) feature uniform and dense closed-cell foam structure and stable resilience. They inherit the advantages of silicone such as high and low temperature resistance, aging resistance, water and dust proof, while possessing the soft cushioning property of foam. They make up for the shortcomings of solid silicone pads which are too hard and poor in cushioning. They can work stably within the temperature range from -60℃ to 200℃. They will not harden or become brittle under outdoor sunlight exposure, high-temperature cavities or low-temperature environments. No permanent deformation tends to occur after long-term repeated compression, so the sealing and shock absorption effect can be maintained continuously. They also have good flame retardant and insulating properties, suitable for protection of electronic control components.

 

II. Foam Series: Solid Type & Foam Type

Foam gaskets cover a wide range of common materials including EVA, CR, IXPE, PU, EPDM, PE, PORON and SBR. They are also classified into solid foam type and foam type. Different substrates have distinct performance and can be selected flexibly according to working conditions.

Solid foam pads feature compact structure with few pores, relatively high hardness, superior wear resistance and shear resistance. They are suitable for load-bearing anti-slip and wear-resistant support positions, and are not easy to deform under compression. They are commonly used for heavy equipment support pads and anti-slip bases.

Foam pads are the most widely adopted type in industrial supporting applications. With internal porous structure, they excel in cushioning and sound absorption.

· EVA foam: moderate hardness, waterproof and aging resistant, for home appliance shock absorption and packaging inserts

· CR neoprene foam: good flame retardant sealing and weather resistance, for outdoor protection and sealing washers

· IXPE foam: fine texture, flame retardant, eco-friendly and low odor, for electronic cushioning and medical supporting parts

· PU foam: soft and resilient, excellent sound absorption and shock absorption, for speaker cavities and automotive interiors

· EPDM foam: weather and ozone resistant, for outdoor sealing cushions

· PE foam: lightweight, waterproof, cushioning and heat insulating, for packaging protection

· PORON foam: high resilience, compression resistance and fatigue resistance, for precision equipment

· SBR styrene butadiene rubber foam: cost-effective, for general wear-resistant cushioning

All the above materials can be processed by die cutting, and non-adhesive or self-adhesive structures are available on request.

 

 

III. Three Core Functions: Anti-slip, Sealing and Cushioning

Anti-slip: Matte anti-slip texture can be processed on the surface. It fits metal, plastic and sheet metal shells without slipping. It is applied to equipment bases, instrument foot pads and home appliance supporting positions to reduce displacement during operation. Self-adhesive versions provide further fixation against shifting.

Sealing: Closed-cell structure effectively blocks moisture and dust, filling gaps of housings. It can be made into frame-shaped sealing gaskets for cabinet covers, lamp housings and power box sealing to achieve dustproof and waterproof effects and protect internal electronic components.

Shock absorption and cushioning: Porous structure absorbs vibration and impact, weakens vibration and noise generated during equipment operation, protects circuit boards and precision components, reduces abnormal noise of the whole machine and extends service life of products.

 

IV. Die-cutting Customization Solutions

Both silicone rubber gaskets and foam gaskets support diversified customization. Non-adhesive types and self-adhesive types are optional. Self-adhesive versions offer firm lamination and convenient peeling and pasting for higher assembly efficiency, while non-adhesive ones allow repeated position adjustment. Thickness, hardness, color and dimensions can be adjusted according to drawings or samples. Round, square, special-shaped, perforated washers, full-frame sealing gaskets and positioning inner supports can be precisely die-cut with controllable tolerances and stable consistency in mass production. Anti-static treatment and lamination can be added as required to suit sensitive electronic parts. We respond quickly to both small-batch sampling and large-volume supporting orders. Customers do not need to source anti-slip pads, sealing pads and cushioning pads separately. Unified docking and acceptance realize true one-stop customization for anti-slip, sealing and cushioning.

V. Application Scenarios and Selection Suggestions

These gaskets are widely used: new energy battery heat insulation and cushioning gaskets, dustproof sealing washers for industrial control chassis, shock-absorbing anti-slip foot pads for instruments, waterproof sealing pads for outdoor lighting, cushioning and noise reduction pads for home appliance motors, vibration isolation pads for medical equipment, shock-absorbing pads for power tools, protective pads for automotive electronics, sealing pads for communication base stations, etc.

Simple reference for selection:

· Prioritize solid silicone rubber pads if high waterproof sealing and wear resistance are required;

· Choose foam silicone rubber pads for high and low temperature environments requiring both sealing and cushioning;

· Select various foam pads for shock absorption, sound absorption and lightweight protection;

· Adopt solid foam pads for load-bearing and wear-resistant support.

Different industries have different requirements on thickness and hardness. During selection, comprehensive judgment can be made combining assembly dimensions, stress conditions, temperature resistance and flame retardancy requirements, and material parameters shall be checked to pick gasket solutions matching working conditions, so as to reduce gasket aging, failure and abnormal noise from the source.

Selection of industrial gaskets needs to consider multiple dimensions. This selection logic combining silicone rubber and foam, and distinguishing solid type and foam type can cover most conventional supporting working conditions, help simplify product assembly structures, unify material standards and cut material management costs.
