The advantages and disadvantages of silicone rubber foam strip and EPDM rubber foam strip are detailed as follows:

First of all, we will first say that silicone rubber foam strip belongs to the class of extruded silica gel, due to the shape like a sponge, so it is called foam silicone strip, or sponge silicone strip silicone rubber foam strip characteristics:

1. Silicone material has good sealing performance, high temperature and weather resistance, anti-aging and anti-beating, shockproof and waterproof, and can fit all kinds of smooth surface materials.

2, can back adhesive tape, better sealing, long - term use of high - temperature adhesive does not fall off. Environmental protection and safety, good insulation, high temperature resistance, small compression deformation, strong resilience, non-toxic.

3. The foaming silicone rubber has uniform foaming, with a density of 0.25-0.85g/cm3 and a hardness of 8-30a. Environmental protection non-toxic no odor, good elasticity, good flexibility, the surface without bubbles and pores. High strength, long service life, product insulation environmental protection, high and low temperature resistance, compression resistance, resistance to acid and alkali aging, uv resistance.

4. Smooth surface and uniform foaming density.

5. A good surface is not sticky. Good air permeability.

6. Adopt high-quality silica gel raw materials, and pass strict testing to meet environmental standards.

7. High temperature resistance: -70 ℃ -300 ℃

8, heat resistance: silicone rubber than ordinary rubber has much better heat resistance, can be used at 150 degrees almost forever without performance changes; Can be used continuously for 10,000 hours at 200 degrees; It can also be used for a period of time at 350 degrees.

9. Weather resistance: ordinary rubber degrades rapidly under the action of ozone generated by corona discharge, while silicone rubber is not affected by ozone. And for a long time in ultraviolet and other climatic conditions, the physical properties of the only small changes.

10, aging resistance, corrosion resistance, silica gel itself has a strong inert silicone rubber foam strip of the use.

Let's talk about the characteristics and shortcomings of EPDM rubber foaming strip. First, let's talk about the characteristics: using EPDM as raw material, smooth and meticulous surface, good elasticity, good foam uniformity, good water resistance, ozone resistance, aging resistance, solvent resistance.

EPDM/ rubber/foam series: polyethylene expanded expanded rubber expansion joint board (caulking board. Caulking board).

Product characteristics of EPDM rubber foam strip:

1. Light bulk density, large expansion strength, non-absorbent (instead of traditional three linoleum, asphalt cedar board and other materials). Product environmental protection, simple construction, anti - seepage, anti - leakage, water - stopping effect.

2. Corrosion resistance, aging resistance, high and low temperature +80℃~-45℃, no flow, no deformation, no brittle cracking, long service life.

3. With the independent opening bubble structure, the appearance of the special joint plate is evenly distributed with honeycomb holes, which can be tightly bonded with cement/sealant without wool, so as to adapt to the change of natural expansion and contraction, and enhance the expansion and water stopping effect of the joint seal.
