Liquid silicone rubber product selection guide

What is liquid silicone rubber?

In today’s guide, you will learn the benefits of liquid silicone rubber (LSR). Besides, we will provide detailed technical information on LSR. It is a high-performing, long-lasting material that can reliably perform in a variety of harsh environments, enabling the development of safe, adaptable and more sustainable products. 

Dow’s portfolio (one of our certified brands) includes specific LSR formulations marketed under multiple brands. Within the range, you can find Injection-molding grades, coating grades, a 3D printing grade, electrical grades, optical grades as well as LSR color masterbatches. It is important to note that these meet safety standards and requirements   for food contact, water contact and infant care applications.

Why choose liquid silicone rubber? 

Liquid silicone rubbers offer a “magic combination” of properties, process and performance to help extend design possibilities for small parts, intricate designs, high precision and overmolding. 

• It is composed of two parts in a 1:1 ratio
• They are easily mixed
• They are quickly heat-cured

Some of the key features of cured LSRs include: good mechanical properties and excellent resistance to weathering as well as extreme temperatures and aging. Moreover, fluoro liquid silicone rubber (F-LSR) combines excellent fuel and oil resistance with LSR processing economy

Implementing liquid silicone rubber for a more sustainable world

As manufacturers, we have a responsibility to use the most respectful and harmless materials to the environment. Dow is committed to delivering solutions that address world challenges, as we aspire to redefine the role of business in society. 

For that reason, with our world-leading operations performance we address natural resource efficiency, supply chain optimization, environmental stewardship, and human health and safety. And just as important to us is delivering breakthrough innovations that enable our customers to address the needs of a rapidly changing world. 

How LSRs are contributing to everyday life in an ever-more-challenging world (H3)

Liquid silicone rubbers produce less waste and require less energy for processing. Some of its key benefits are the following:

• Design flexibility, enabling innovation
• Long-lasting photothermal stability 
• Safety, as it is resistant to flammability and to long-term contact
• Environmental seal, as it is water and dust resistant
• Transparent and lightweight
• Versatile and cost-effective
• Colorless, odorless and tasteless
• It can be sterilized multiple times
