How to Choose Silicone Sponge for Extreme Temperature Environments


The medical sector and the food industry depend considerably on silicone sponge sheets. Factors that work in favor of this material are its low toxicity, thermal stability, and resistance to micro-bacterial growth. Specific grades of silicone can retain their flexibility in extreme temperatures, ranging from very low to unbearably high.

Every silicone distributor aims to manufacture a high-quality material that conforms to critical safety standards, is dependable, and outperforms even in harsh environments. There are silicone sponges designed exclusively to withstand fluctuating temperatures yet, manage to retain their robust and durable properties. These can even tolerate the immense heat generated when machines are run for prolonged durations at high speeds.

While choosing silicone sponges for use in extreme temperatures, adhere to the following guidelines to arrive at your best bet:

Assess Construction

Heavy-duty sponges are specifically built to tolerate severe conditions, which include extreme temperature environments. It is preferable to avoid a delicately designed soft sponge when you are clear of the purpose your silicone sponge will serve.

Subjecting a fragile sponge to severe conditions will only result in disappointments later. The same is not the case when you invest in a sturdy silicone sponge. A heavy-duty sponge, even when it has a rough texture to withstand harsh settings, still proves safe owing to its non-toxic nature.

Examine Certifications

A reputed silicone distributor will always sell certified silicone sponges. The certifications that are usually clearly displayed on the product include BPA-free, and FDA approved. The products undergo a series of industry specific tests to earn these certifications.

Only it successfully clears them; the certification is granted. When you purchase a certified commodity, you can be sure that it has been subjected to extreme temperatures to test its performance in all situations.

Scan Packaging

Carefully scanning the packaging gives you valuable inputs in terms of highlighting features of the silicone sponge. A confirmation of the sponge possessing antibacterial properties is a direct indication of it being odor resistant. This attribute ensures that strong smells do not linger within the sponge particles.

Given that such sponges are long-lasting, constant use can play havoc should it retain bacteria that result in unbearable odors. Silicone sponges are very capable of being odor resistant and useful at the same time.

Scrutinize Cells Within

The natural properties of closed cell silicone sponges keep them insulated from heat, electricity, and vibrations. They also successfully keep out dirt and other external elements; hence, it must be your preferred choice. These features are in sharp contrast to sponges with open cells. The latter is highly absorbent and retains all the moisture as well as other unfavorable intruders.

A non-porous, closed-cell silicone sponge can withstand extreme temperatures, and also resist environmental elements like ultraviolet rays, bacteria, water, and mildew.  Another plus of closed-cell sponges is that they quickly regain their natural shape after undergoing compression, stretching, and other actions that temporarily deform their appearance. The bottom line being, approach only reliable companies that are known to serve their clients well by guiding them in the right direction.
