Material characteristics of various sealing rings

With the rapid development of modernization of construction projects, doors and windows used in buildings require not only overall beauty, but also good decorative effects. Doors and windows also need to have high-quality sound insulation, dustproof, shock absorption, sealing and other properties. As one of the accessories for doors and windows, the use of door gap silicone rubber sealing strips can be an important guarantee for it to obtain the above excellent performance.

Silicone sealing strips, it is not afraid of high temperatures and resists severe cold, minus 90~300℃ has no change, still has high-strength elasticity, tensile strength can reach 14.7-17.7MPA, excellent tensile resistance, compression resistance and deformation, hardness can be adjusted between 10-80 Shores according to requirements, can be made into colored products, easy to color, non-toxic, odorless, green and environmentally friendly;

Material characteristics of silicone sealing strips:

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

2. The backing tape can be self-adhesive, with better sealing, and the high temperature resistant glue will not fall off after long-term use. Environmentally friendly and safe, good insulation, high temperature resistance, small compression deformation, strong resilience, non-toxic.

3. The foamed silicone rubber foams evenly, the density can reach 0.25-0.85g/cm3, and the Shore hardness is 8-30A. Environmentally friendly, non-toxic and odorless, with good resilience, good flexibility, and no bubbles or pores on the surface. High strength, long service life, product insulation and environmental protection, high and low temperature resistance, compression resistance, acid and alkali resistance, anti-aging, and UV resistance.

4. The surface is flat and the foaming density is uniform.

5. Good surface non-stickiness. Good air permeability.

6. Made of 100% high-quality silicone raw materials, and strictly tested, in line with environmental protection standards.

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

8. Heat resistance: Silicone rubber has much better heat resistance than ordinary rubber. It can be used almost forever at 150 degrees without performance changes; it 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 its physical properties only change slightly under ultraviolet and other climatic conditions for a long time.

10. Anti-aging and corrosion resistance, silicone itself has strong inertness.
