Semi-Closed Cell EPDM is engineered as an ultra-soft, low-compression sponge, ideal for applications that demand a pliable, conformable material. This unique polymer is renowned for its exceptional UV and ozone resistance. UL flame-rated options are also available.
The cell structure of Semi-Open Cell EPDM is created in the manufacturing process by physically "bursting".
The closed-cell structure in order to create a product that is softer and therefore easier to compress than the more traditional medium or firm grade semi open cell EPDM sponge.
2.Why use Semi Open Cell EPDM Foam?
A semi-open cell EPDM sponge combines the flexibility and compressibility of open-cell foam with the superior sealing properties of a closed-cell sponge when compressed.
This durable material retains the excellent ozone and weather resistance of standard EPDM while offering a slower, more controlled recovery after compression, making it ideal for sealing applications.
Available in sheet or roll form, as well as pre-cut parts, semi-open cell EPDM sponge is a reliable solution for both indoor and outdoor sealing needs, effectively protecting against air, dust, and moisture.
3.Who we are ?
Topsun, the Professional supplier for the Foams, we can provide a variety of foam products, such as EVA foam, PE foam, neoprene foam, EPDM foam and NBR foam.At the same time, we have advanced processing capabilities to convert foam into the products you need.
4.What kinds of foam materials we can supply ?
We can supply :EVA foam, PE foam, XPE foam, IXPE foam, CR foam, EPDM foam, Neoprene foam, SBR foam, NBR foam, Micro-cell soft PVC foam. All of them we can supply in sheet and roll.
5.What's the processing capacity we have ?
1. Cutting - cutting the size as per client’s request
2. Slicing - Slicing the thickness as per client’s request
3. Lamination - hot melt film lamination, flame lamination, and pressure-sensitive adhesive lamination
4. Laser Vibrator - New type cutting machine, can cut the foam drawing without open molds
5. Die cutting - Open molds as per your design then at first, use die cutting machine to produce, it’s quicker than laser vibrator.
6. Compression Molding - Compression molding is a process we utilizes for the manufacturing of three-dimensional molded foam and foam composite parts. It is an ideal process for making parts that have intricate features, require very defined part geometry, have varying wall thicknesses or need to be held to critical dimensional tolerances.
7. Engraving machine - Usually to make tool box insert and packing insert as per client’s requests.
8. Silk-screen printing - Print logos and patterns on the surface of foam products
9. Adhesive backing - Gluing on the surface of the foam with liners. Usually produce foam tapes and other products need to stick on.
6.Where is our facility located ?
Our factory is located in Changzhou city, Jiangsu Province. One hour driving to Shanghai Port.
7.How to get samples ?
Send enquiry to july@topsunfoam.com, with your details of the foams need, we will check reply in 24 hours.We are committed to continuously providing excellent products and services to customers worldwide
