What is Liquid Silicone Rubber?
Liquid Silicone Rubber is a versatile material with unique properties that make it stand out in the world of elastomers.
Here’s an overview of its key characteristics, let’s take a look!
Definition and Composition
- Nature: LSR is a high-purity platinum-cured silicone.
- Form: It is in a liquid state, which significantly differs from the more traditional, solid silicone rubber.
- Components: LSR consists of a two-part system, typically labeled as Part A and Part B. One part contains a platinum catalyst, while the other contains a cross-linker or a curing agent.
Properties
- Thermal Stability: LSR maintains its properties over a wide temperature range, typically from -55°C to 300°C.
- Chemical Resistance: It is highly resistant to chemicals, water, and oxidation.
- Electrical Insulation: LSR is an excellent insulator, making it ideal for electronic applications.
- Biocompatibility: It is non-toxic and can be sterilized, qualifying it for medical applications.
- Flexibility and Durability: LSR is flexible, has a high tear strength, and is resistant to aging and weathering.
- Transparency and Colorability: It can be made transparent or colored as per requirements.

4 Benefits of Importing Liquid Silicone Rubber from China
Importing from China will give you the benefit of high-quality products with other benefits as compared to other countries.
Qualify Suppliers
Many “suitcase companies” claim to deliver excellence to you, making it difficult to do background checkups. They look like glamorous corporate websites that you can’t doubt to be illegitimate or scammer companies. However, China has no central point requiring a background check. Simply do a general online search or hire a consulting firm to analyze high-value products.
Safe Term Of Payment
Import from Chinese manufacturers ensures a safe payment term compared to other countries. They usually accept a 30% deposit and 70% by TT as a standard payment option on the first shipment. You can also communicate with manufacturers and suppliers on your product requirements to satisfy and then triple-check.
Easily Customizable
You can easily customize the products by importing from China as per your requirements. Chinese imports are more considerate about customer satisfaction as compared to other countries. This engages the buyers more towards them as they deliver authenticity as you want them to.
Large Quantities Are Easily Available
Most companies look for importing in more significant quantities where other countries fail except China. They are also known for their massive market and giant structures prepared for manufacturing large product runs.
