Silicone foam strips are a two-component sulfur-silicone rubber, made by mixing silicone and curing agent in a 1:1 ratio to form an oily liquid, which, after vulcanization, becomes a soft elastic material. Below is a detailed introduction to silicone foam strips.

Silicone foam strips offer excellent high-temperature resistance, up to 300 degrees Celsius. They are food-grade, odorless and non-toxic, meeting FDA-certified food-grade standards. Soft and elastic, they make excellent eco-friendly fillers. Bubble ratio: 2-6 times, suitable for use at room temperature. Finished product density: 200-500 kg/m³.

Silicone foam strips are products based on silicone oxides, widely used in industries such as electrical components, electronics, furniture, toys, hardware, sports equipment, audio, lighting, machinery, automobiles, sealed bottles, and building facade sealing due to their non-toxicity, environmental resistance, high transparency, and elasticity.

Method for Quality Assessment of Foam Silicone Product Strips:

One: The touch method: The silicone foam strips have good elasticity, can be directly touched with the hands to check for elasticity, which is one of the basic methods.

Secondly, Incision: Cut the silicone tube with scissors, observe and leave it for a while to allow the incision surface to curve slightly, but not completely flat. A higher curve increases the adhesive content of the product, thereby enhancing its quality, especially during the high-temperature vulcanization process, where the finished product shows a more pronounced improvement.

Thirdly, Burn Test: First, cut a piece and hold it with tweezers or scissors, then ignite it with a lighter or match. Observe the smoke; it should be white or gray. High-quality silicone foam strips, when burned, produce ash that is either white or gray with no discernible刺激性 odor.

In summary, poor-quality silicone foam strips have a rough surface, low strength, and are prone to deformation and cracking upon folding. They emit a pungent smell. When burned, due to excessive filling material and minimal resin, the melted fibers are short. High-quality silicone foam strips feature a smooth surface, high strength, good elasticity, and no odor. Upon burning, the flame appears yellow at the tip with a green base, emitting a scent.
