Before you decide between solid and hollow rectangle silicone rubber strips, know the following differences about them:

· Weight Comparison

If you need strips that are light to meet specific work needs, stick with hollow silicone rubber strips. They are lighter compared to solid ones.

· Load and Force

Solid silicone rubber strips are perfect for high pressure or structural sealing. On the other hand, hollow silicone rubber strips are perfect for insulation and cushioning.

· Cost

You will save more money with hollow silicone rubber strips compared to solid silicone rubber strips. So, if your project will not require the strength slid strips bring, stick with hollow strips.

· Environmental Factors

Solid and hollow silicone rubber strips both have exceptional resistance to temperature and UV light. Nonetheless, solid strips have an added property of being highly durable which hollow silicone rubber strips don’t have.
