The hydrophobic methyl side groups of Liquid Silicone Rubber (LSR) account for its low surface energy and water repellence. An average value for silicones is 24 dynes/cm or 0.024 N/m. The surface hydrophobicity of a solid surface is determined by … Continue reading
Like all silicones, Liquid Silicone Rubber (LSR) is characterized by a flexible, fully saturated backbone of alternating silicon and oxygen atoms. The siloxane bonds have a partial ionic nature and give the material its high strength. The backbone is shielded … Continue reading
While today’s popular non-stick bakeware products manufactured out of Liquid Silicone Rubber (LSR) are flexible to the touch, they maintain a certain degree of resistance to deformation. While ear buds or in-ear headphones, on the other hand, require a close … Continue reading
The elemental structure of Liquid Silicone Rubber (LSR) enables the material to have a very low compression set; normally in the range of 20 – 40% (22 h @ 350ËšC). A low compression set means LSR retains its elastic properties … Continue reading
Professor Tim Osswald, Director of the Technical Advisory Board of SIMTEC Silicone Parts, presented breakthrough research on the viscoelastic behavior of Liquid Silicone Rubber (LSR) at Silicone Elastomers US, the first Silicone Elastomers’ event held in North America. The presentation … Continue reading
