Product Description

107 Hydroxy-Terminated Polydimethylsiloxane:In RTV mold silicone rubber, defoamer, silicone glass glue as the main raw material.

Chemical name : OH Terminated Polydimethylsiloxane / Hydroxy Silicone Oil / OH Termianted Silicone Oil / OH Terminated Silicone Polymer / Hydroxy Polydimethylsiloxane

CAS No. : 63148-60-7/70131-67-8

EINECE : 615-070-3

Apperance : Colorless Transparent Liquid



Physical And Chemical Features : 

1. High and low temperature resistance.

2. High flash point.

3. Low freezing point (it can be chronically used in the temperature from -50℃ to +250 ).

4. Small viscosity-temperature coefficient.

5. Big compression ratio and low surface tendency . Water-repellent and moisture resistant.

6. High and low temperature resistance.



Advantages :

1. Silicone oil is a colorless, odorless, non-toxic and non-irritating products, chemical stability, heat resistance, cold resistance, water repellency, lubricity, high refraction, storage stability and compatibility with commonly used in many filed.

2. Silicone fluids are 100% PDMS silicone oils that are characterized by their wide service temperature range, high flash points, high dielectric strength and excellent lubricity.

3. Silicone Fluids are widely used in Flow Control, Temperature Control and Motion Control technologies. They are especially advantageous for instruments, gauges and devices that are subject to extreme temperatures and high pressures.

4. Silicone’s excellent thermal and photo stability minimizes the risk of yellowing or changes in properties during device fabrication and use. In addition, our silicone coatings, potting materials, adhesives and sealants offer superb mechanical properties and provide strong protection of sensitive LED.

1. What Is OH Terminated polydimethylsiloxane?
JH107 is made of siloxane monomer polymerization,and both ends of the molecular has hydroxyl organosilicon material. Its structural formula is: HO[-Si(CH3)2O[Si(CH3)2O]nSi(CH3)2-OH.Chemical name is a hydroxyl terminated polydimethylsiloxane.Customarily,hydroxyl silicone oil with viscosity over 2500mPa.S is called 107 silicone rubber.In addition to the general properties of methyl silicone oil,the product also has a hydroxyl reactivity.It can be used to make some new materials,or cross-linked into elastomers(or film).This product is colorless and transparent liquid,with excellent electrical insulation and resistance high and low temperature.Due to high flash point and low freezing point,it can be used in the below 50℃~+250℃ for a long time.It features a low viscosity-temperature coefficient,high compressibility,low surface tension,good hydrophobic and moisture resistance,chemical inertia and physiological inertia.
