Door and window sealing strip manufacturers tell everyone that the carrying size and expansion properties of silicone sealing strips will directly or indirectly endanger the service life of silicone sealing strips, which are harmed by the appearance of the actor himself, and by the installation forms such as floor plans, convex grooves or pipe grooves. The installation forms of each sealing ring are different, which may cause uneven force and deviation of the center of force, resulting in heavy and light conditions. In this kind of long-term inventory backlog and uneven force, it is very easy to cause expansion and deformation. When the silicone rubber sealing ring is disassembled again, it may have been deformed. Therefore, the level of balance and carrying capacity needs to be controlled during assembly. Symmetry and comprehensiveness.

Sometimes, the deviation of the specification of the silicone sealing strip can cause voids and deformation.

The problem of voids can be divided into several factors. One is the problem of plastic particles of the material. Due to the secret recipe, many silicone products may have poor resilience and insufficient tensile strength, which leads to voids in the process of adoption, leading to leakage. Second, there are problems in the production and processing of silicone products. The silicone sealing strip is thin when the product is fragile, and the inner bulge of the commodity plastic particles is not familiar when the product is soft, and the gap problem occurs after long-term stretching.

The harm of soft power, in many cases, the difference in the softness of the silicone sealing strip can change the basic functions and structure types of the commodity. Therefore, in the entire application process, due to the different choices of soft strength, the silicone sealing strip will have inevitable problems, such as gaps, excessive bearing capacity, excessive strength, and difficulty in the resilience of the commodity deformation.

So the silicone sealing strip can be used for two years?It can only be known according to various testing methods, but if you know what causes the service life of the silicone sealing strip to be shortened, you can take preventive measures to the greatest extent, thereby extending the service life of the silicone sealing strip.

What are the advantages and disadvantages of silicone sealing strips for door and window sealing strip manufacturers?

Advantages of silicone sealing strips

1. Good sealing function, waterproof and non-leaking, environmentally friendly and non-toxic;

2.Can be heated at high-intensity temperatures without deformation, no harmful substances;

3.Excellent tensile strength characteristics;

4.Long-term use will not change the yellow color;

5.Resistance to corona discharge, arc resistance, high and low temperature resistance, good anti-aging properties and heat resistance;

6.Good temperature resistance, silicone rubber sealing ring can be used for a long time at 150 without characteristic changes, continuously used at 200 for 10,000 hours, or temporarily used at 250;

7.The silicone sealing strip has good cold resistance. The general plastic is -20-30, while the silicone sealing ring still has good ductility at -50-60. Some special low-temperature resistant silicone materials can also withstand lower temperatures.

Defects of silicone sealing strip

The silicone sealing strip is not resistant to acid and alkali, and is not suitable for most thick organic solvents, refined oils, thick acids and dilute sodium hydroxide solutions.
