What are the factors affecting the sealing effect of Polyester/cotton Braided Sleeve?

Polyester/Cotton Braided Sleeve are environmentally friendly and pollution-free. After strict testing, they have passed RoHs and eight heavy metals and other specifications. Polyester/cotton Braided Sleeve are 100% completely non-toxic and tasteless. Supporting mechanical products such as electronics, automobiles, and medical treatment.

The factors affecting the sealing effect of polyester/cotton braided sleeves are mainly determined by the choice of sealing structure and oil film formation, pressure, temperature, compatibility of materials, and the material, hardness, geometry, and surface finish of the working surface in contact with the dynamic seal. of.
The oil (liquid) resistance of rubber material seals generally uses standard test oil, soaked under the temperature conditions and test time specified in the test standard, and compares the test values before and after soaking (such as material hardness change, tensile strength change rate, elongation at break, volume change, compression*deformation, etc.) to evaluate its performance.
1. The standard oil is a "low volume gain oil", a mixture of mineral oils composed of solvent extracted, chemically treated, dewaxed paraffin residues and neutral oils;
2. The standard oil is a "high volume increase oil", which is composed of two kinds of lubricating oil components obtained by vacuum distillation of crude products of naphthenes after selection. The index value assessment of the material silica gel strip is different for different purposes.
Cable Sleeve structure: Cable Sleeve is also a chain structure formed by polymer molecules connected by SI-O (silicon-oxygen) bonds. The SI-O bond is 443.5KJ/MOL, much higher than the C-C bond energy (355KJ/MOL), and because of its unique molecular structure, the Cable Sleeve has better heat resistance, electrical insulation, chemical stability etc.
