EPDM Salt Vulcanized Seal Strip
Main Specificaton >>>>>>>
Salt bath sealing strips are rubber strips produced through continuous vulcanization in a salt bath. The core of this process lies in using molten salt to achieve rapid heating and shaping. Compared to sealing strips produced by traditional vulcanization, salt bath sealing strips offer precise dimensions and a smooth, flat surface, making them widely applicable in various scenarios such as automobiles, rail transportation, home appliances, and electrical distribution cabinets.

Salt Bath Sulfidation Process: >>>>>>>
1. Rubber compounding: Mixing rubber materials with vulcanizing agents to create a homogeneous rubber compound.
2. Extrusion molding: Extruding the compounded rubber compound to form the desired sealing strip.
3. Salt bath vulcanization: Immersing the sealing strip in a molten salt bath for vulcanization.
4. Water washing and cooling: Washing the vulcanized rubber strip in a water tank to remove surface salt.
5. Traction and winding: Finally, cutting and winding the sealing strip.
Product Advantages >>>>>>>
1.Uniform vulcanization: The rubber strip surface is smooth and free of bubbles, with an exquisite appearance.
2.Extremely low compression set: It will not deform or collapse even after long-term use.
3.High production efficiency: Fast heating speed and high precision result in higher production efficiency.
Comparison of vulcanization processes>>>>>>>
Comparison Projects | Traditional vulcanization process | Salt Bath Sulfidation Process |
Vulcanization Efficiency | Vulcanization is time-consuming and inefficient. | Fast vulcanization speed and high efficiency |
Surface Quality | It is prone to producing bubbles, flow marks, etc. | The surface is smooth and clean, with no obvious bubbles. |
Dimensional Accuracy | General accuracy | High dimensional accuracy |
Heat transfer effect | Relying on air or microwave heat transfer results in poor temperature uniformity. | Molten salt comes into direct contact with the rubber strip, ensuring uniform heat transfer. |
Long-term sealing | Prone to deformation with prolonged use | Not easily deformed, long-lasting and stable |
Main Application Scenarios>>>>>>>
EPDM salt bath vulcanized sealing strips possess excellent resistance to aging, ozone, high temperatures, and low compression set, making them widely used in various fields such as automotive manufacturing, building doors and windows/curtain walls, machinery, and home appliances.
1.Automotive Manufacturing: Car doors, trunks, engines, sunroofs, etc.
2.Building Doors and Windows: Aluminum alloy doors and windows, wooden doors, security doors, curtain walls, etc.
3.Home Appliances: Refrigerators, ovens, LED lights, air conditioners, etc.
4.Machinery: Machine tools, excavators, mining and metallurgy.
