What is the difference between liquid silicone rubber(LSR) and solid silicone rubber?

Liquid Silicone Rubber is Liquid, Solid silicone rubber is solid and no fluidity. The finished Liquid Silicone Rubber and solid silicone rubber are not easy to distinguish. Liquid silicone rubber finished products has high transparency and odorless with injection feeding mouth, While the finished products of the solid silicone rubber have low transparent.

 

Solid Silicone Rubber

Solid silicone rubber can be made into all kinds of silicone products after vulcanization. Comparing with the injection molding process, the most advantageous of compression molding is the lower cost. The solid silicone molds are cheaper, and the raw materials are also less expensive. Processing is highly variable, so that, a wide range of different parts can be made with a few basic silicone grades.

But the disadvantage is that the manual operation, the self-demolition mold line has no liquid perfection, and the most softness of the product only reaches about 20 degrees.

How to store the Solid Silicone Rubber

  •  Store in closed containers in cool rooms at 0- 30 °C
  • Do not expose to direct sunlight
  • Keep separate from organic rubber and crosslinker chemicals

 

Liquid Silicone Rubber

The liquid silicone is liquid. In the production process, the liquid silicone raw material is injected directly into the mold cavity. The process can be fully automated. It does not need to involve a lot of labor. The product is sealed and processed. Therefore, It produces high-quality parts without secondary finishing, and the processing speed is fast. Injection molding is suitable for complex part geometry. Liquid Silicone Rubber is widely in Medical and Baby Care Products.

The disadvantage is that the cost is high, the mold development cost is expensive, and it is uneconomical for the production of small-batch products!

How to store the Liquid Silicone Rubber

  •  Store in closed containers in cool rooms at 0 – 30 °C
  • Higher average temperatures may shorten the shelf life
  • Do not expose to direct sunlight
  • When opening the container, make sure that no dirt falls onto the surface of the rubber
