Introduction to low hydrogen silicone oil:
1. Chemical name: methyl low hydrogen silicone oil
In addition to the characteristics of dimethyl silicone oil, this product can produce addition and crosslinking reactions due to the presence of active hydrogen.
Second, the main technical indicators
Appearance: colorless transparent oily liquid
Refractive index (25 ° C): 1.39-1.41
Flash point: 140 ° C
Density (25oC): 0.98~1.10
Viscosity (25oC, mpa.s): 50~200 (special specifications according to user requirements)
Hydrogen content (%): 0.18~0.80 (special specifications according to user requirements)
Third, the general performance and use:
This product is colorless and transparent oily liquid. It is non-toxic and tasteless. Because it contains a certain amount of relatively active Si-H bond in the molecule, it has a reactive group. Under the action of the catalyst, it can react with groups such as double bonds and hydroxyl groups. The basic raw materials for sealants, potting compounds, foam stabilizers, defoamers, water-soluble silicone oils and other products. It can also be used as a waterproofing agent and softener for natural and synthetic fiber fabrics, silk, leather, etc., and can be used with hydrogen-containing silicone oils having different hydrogen contents and different viscosities.
Fourth, the amount of low hydrogen-containing silicone oil added in the addition of silicone rubber
Low hydrogen-containing silicone oil used in liquid addition molding silicone rubber, that is, the ratio of vinyl silicone oil and hydrogen-containing silicone oil, and the ratio of dimethicone (for reference only): 1:0.095:0.28, of which The vinyl silicone oil is 350cs, and the hydrogen silicone oil is 0.35%. This is the experimental reference index of our company's Foshan Huagu Silicone Factory. The specific production ratio should be based on the customer's own experiment.
