Process/ Material | Standard Vinyl | Hi-Temp Vinyl | EPDM | Silicone |
Maximum Temperature | 225° F (107° C) | 446° F (230° C) | 475° F (246° C) | 600° F (316° C) |
Painting -Air Dry | Lowest cost alternative. | Functions well. Higher cost alternative. | Functions well. Costly alternative. | Functions well. Costly alternative. |
Painting with Bake up to 350° | Will withstand some low-cure processes. | Works in most processes at significantly less cost than Silicone or EPDM. | Typically only used if Hi-Temp vinyl does not perform. | Functions well. Costly alternative. |
Powder Coating | Less effective then Hi-Temp vinyl. | Works in some processes especially when using large masks. One time use. Wash caps to remove any mold release. | Works in most processes. Fewer passes than Silicone products. | Works in nearly every process. Get multiple passes as powder is easily cracked off. |
E-Coating | Typically will not withstand bake temperatures. | Low cost alternative. Specify industrial wash to eliminate mold release. | Works in most processes. Fewer passes than Silicone products. | Works in nearly every process. Get multiple passes as powder is easily cracked off. |
Plating | Lowest cost alternative, but some chemicals may break them down. | N/A | Great chemical resistance makes these a safe choice for most plating processes. | Costly alternative. |
