In modern manufacturing, silicone foam strips and high density foam have developed as almost indispensable materials, as each has its own set of advantages. Because of their elasticity, strength, and moisture propagation resistance, silicone foam strips are well suited for sealing applications. High density closes up the gap due to its good load bearing properties as well as benefitting from surface mounting. There are characteristics for these materials which, when known, help the companies identify the best option to improve the overall quality and the performance of the product.
