Product Description

1): hardness material is divided into different hardness,50 /60 /65 /70 /75/ 80 degree, hardness test : hardness, hardness higher numbers, produced by the product quality is hard.

(2): physical properties of raw materials. Tear: refers to the experimental product testing much force, can be broken, the standard value is:7 MPA min. Products: the longest tensile pull to how much it will fracture (the standard test piece ), minimum standards are: 300% min. Anti deformation: a standard test product deformation, placed150 degrees Celsius in the oven bake for 24hour, removed after cooling, the deformation value.

(3): the proportion of product of the density, the standard value:1.28 2tube structure: Hose with silica gel and a cloth layer combination, silica gel and cloth materials quality, directly related to the resistance / heat pipe / service life. 

We usually use the silicone tube, silicone raw materials requirements as above. Cloth cloth: divided into two - mesh cloth / flat weaving. The cloth is yellow with the characteristics of high temperature, the lowest at180 degrees Celsius, test way: with200 degrees centigrade oven for 4hour, cloth No yellow, no zoom, two features are: A mesh cloth : used for pipe / different-diameter pipe / tube. Advantages are: good tensile properties, easy molding, hose appearance beautiful, the shortcoming is: relative pressure resistance is poor. B flat weaving : used for straight pipes and tubes of different diameters. Advantages: better products with little deformation resistance. Disadvantages: large processing difficulty, high cost.
