The Secret To High-Precision Liquid Silicone Rubber Molding

When is Liquid Silicone Rubber the Best Choice?

One of the primary advantage of liquid silicone rubber elastomer. LSR materials are offered in a wide variety of grades: general purpose, food-grades, medical, self-adhesive, low-volatile, optically clear and numerous other specialty grades, each in a range of durometers – from very firm to very soft. Liquid silicone rubber elastomer are also inherently insulating, offering superior heat and flame resistance ideal for electrical, automotive, and industrial applications. LSRs are also naturally biocompatible and hypo-allergenic making them a choice material for skin-contact products. LSR’s physical properties are also a key factor contributing to their popularity. Due to its high compression set, an LSR part will maintain its original shape after numerous compression/uses, even in extreme high and low temperatures – a differentiating factor between liquid silicone rubber and other elastomer polymers. These highly versatile silicone materials are naturally translucent white in color however they can be pigmented in a variety of colors.

What Makes Silicone Rubber So Desirable?

Silicone rubber is a synthetic elastomer made from silicon, oxygen, hydrogen, and carbon. Known for its exceptional resistance to extreme temperatures, ranging from -60°F to 450°F[KC1], silicone rubber is highly durable and flexible. It also possesses strong resistance to environmental elements like UV light, moisture, and ozone, making it suitable for outdoor and demanding applications.

These properties make silicone rubber the go-to material for industries that require long-lasting, high-performance solutions. Its ability to maintain stability in harsh conditions allows manufacturers to rely on it in critical applications.

Below, we will review the wide range of silicone rubber applications across industries such as automotive, energy, aerospace, and more, demonstrating its integral role in modern technology and infrastructure.
