Product Description

 

Product Description

 

Features

Hydroxyl silicone oil is made by polymerization of siloxane monomers, the molecular silicone materials have hydroxyl groups at both ends. The structural formula is as follows:

HO-Si (CH3) 2 O [Si (CH3) 2 O] n Si(CH3)2-OH

Chemical name is a, w- dihydroxy polydimethylsiloxane, it name 107 silicone rubber when the viscosity is above 2500mPa.S. In addition to the general performance of methyl silicone oil, it also has reactive hydroxyl groups, it can be made available some new material or crosslinked into elastomers (or membrane) .

Colorless transparent liquid with excellent electrical insulating properties and resistance to high temperature, high flash point, low freezing point, long-term used -50 o C ~ +250 o C conditions, low the viscosity-temperature coefficient, high compression ratio, low surface tension, hydrophobic moisture resistance, chemical inertness, physiologically inertness.
 

Specifications:

Appearance : colorless transparent liquid.

Viscosity (25oC, mpa.s): 25~100000 (can be customized according to user requirements ).

Hydroxyl content (%): 0.5 - 3 (related to the viscosity).

Application:

Depending on the hydroxyl content and viscosity, respectively for different industries .

1. the medium-high viscosity of the product can be used as a paper -based of anti- adhesive agent, the cured film has excellent anti-sticking effect, such as the label backing paper , asphalt wrapping, sealing tape base paper, decor paper end paper processing.

2. in the electrical power industry as the main component insulating paint or a component of the insulator.

3. Used as a condensation-type RTV silicone rubber based adhesive and diluted material, such as sealants and plastic mold base material.

4. Alter dimethyl silicone oil, and easy to emulsify .

5. Small molecule hydroxyl silicone oil (25 ~ 30CP, hydroxyl content of about 8%) is an excellent control agent of silicone rubber, it not only simplifies the process of silicone rubber to improve the processing performance ( reduce heat treatment ) but also increased the transparency of products, improved working conditions.

6. New development applications.
