    摘要: A sealant gel for a telecommunication enclosure, wherein the gel is formulated from three different polyols in a manner that maintains its favorable mechanical properties given environmental conditions, for example, over a wide temperature range. The first polyol is a polybutadiene-based polyol that has a low glass transition temperature that provides excellent low-temperature performance. The second polyol is a polyether polyol, which is very flexible and contributes the necessary viscoelastic properties. The third polyol is butene diol, which is a short molecule that quickly builds up a hard backbone structure that helps promote fast curing and provides high-temperature resistance. The combined formulation for the sealant gel builds up a well-balanced network structure that not only has all the necessary viscoelastic properties, but also withstands the highest required temperature of 120° C. while also exhibiting good performance at subzero temperatures. A telecommunication enclosure that utilizes the sealant gel is also disclosed.
