Physical and Chemical Properties | The properties of polydimethylsiloxane alcohol are unique and easy to spread. Used for shampoo and hair care products, it can increase the smoothness of the hair, improve the luster, and have no greasy feeling. Used in skin care products, it can make skin feel as smooth as silk. Compared with the standard polydimethylsiloxane, this product has lower greasy feeling, but the smooth effect is not reduced. |
Use | Introduction Polydimethylsiloxane (PDMS) is a polymeric organosilicon compound commonly referred to as a silicone. With optical transparency, light transmittance of 100%. Therefore, the polydimethylsiloxane itself is transparent, but when sold, it is generally emulsified and sold in an emulsion state. |

POLY(DIMETHYLSILOXANE), HYDROXY TERMINATED - Introduction
POLY(DIMETHYLSILOXANE), also known as HYDROXY TERMINATED, is a polymer containing hydroxyl functional groups. It is a colorless or yellowish liquid with low viscosity and good chemical stability.
This polymer has the following main properties:
1. High temperature stability: can withstand the application under high temperature conditions, and maintain chemical stability and physical properties;
2. Low temperature performance: at low temperature still maintain soft deformation, no brittle;
3. Chemical resistance: good resistance to acid, alkali, solvent, etc;
4. Excellent electrical insulation properties: widely used as electrical insulation materials;
5. Good lubrication performance: excellent performance in friction and lubrication applications;
6. Biocompatibility: can be accepted by the organism, and used in the biomedical field.
Due to these unique properties, POLY(DIMETHYLSILOXANE), HYDROXY TERMINATED is widely used in many fields, including but not limited:
1. Electronics industry: used for encapsulation, insulation and lubrication of electronic components;
2. Cosmetics and personal care products: as emulsifiers, lubricants, anti-foaming agents and solubilizers;
3. Medical equipment: used for the production of artificial organs, emulsion, medical tape, etc;
4. Coatings and coatings: good wear resistance, chemical resistance and high temperature resistance;
5. Textile industry: used for fiber lubrication, increase elasticity and antistatic;
6. Rubber industry: It can increase the processability and softness of rubber.
The preparation method of POLY(DIMETHYLSILOXANE), HYDROXY TERMINATED is usually obtained by reaction. One common method is to react the corresponding Silicon monomer with an organic hydroxy compound to form a hydroxy-terminated polydimethylsiloxane by addition polymerization of a hydrated silane.
Regarding safety information, such polymers can generally be considered relatively safe. However, due to differences in individual sensitivity and application environment, correct operating procedures should be followed and necessary personal protective measures should be taken during use. During use and handling, contact with skin, eyes and respiratory tract should be avoided, and good ventilation conditions should be maintained. In case of ingestion or contact, wash and consult a doctor.
