What will happen if the glue participation rate of the silicone hose is high?
The high or low rubber mixing rate of silicone hoses depends on the product and cannot be generalized. Some people say that 50% is high, and some say that 70% is still low. The cost is high, the shrinkage rate of the glue is large, the elasticity is good, the hardness is not very high, and the strength is not necessarily (depending on the type of glue). What can use such a high glue content? Is it a product with high resilience? ?

Silicone tubing material NR-based shock absorption, if the hardness is only about 40 degrees, 70% glue content in other formulas is quite common. Excessive glue content: What will happen? This is related to the type of glue. It depends on what kind of glue it is: if it is a high-viscosity glue, the fluidity is definitely not good, and the burrs are not easy to tear. For example, crystalline rubber and non-crystalline rubber have high glue content and are not easy to tear the edge. One is high strength and is not easy to tear, and the other is poor strength and is not easy to tear. Because the strength of amorphous rubber raw rubber is poor, the higher the rubber content, the lower the strength. Of course, when the rubber content is high, the product must have a large shrinkage rate, poor dimensional stability, poor mixing processability, and severe shrinkage of the mixed rubber film.
