Chemical Description: Ultra-Low Cyclic Hydroxyl-Terminated Polydimethylsiloxane

Product Description:

The NV-SiOH107L Series represents a premium grade of linear, hydroxyl-terminated polydimethylsiloxanes (OH Silicone Oils) meticulously refined through advanced stripping technologies. Engineered specifically to address stringent regulatory requirements, this series features an ultra-low content of volatile low-molecular-weight cyclic siloxanes (D3–D10 ≤ 300 ppm) and exceptionally low total volatile content (≤ 0.2%). It is the ideal choice for high-end formulations demanding superior purity, safety, and performance.

Typical properties:

Appearances:colorless transparent highly viscous liquid

Appearance:Colorless transparent liquid

Metal ion content<50PPM

Chloride ion content<50PPM

* The D3-D10≤ 100PPM/200PPM can be customized.

* The viscosity can be customed according to your request.

Key Features & Benefits

Ultra-Low Cyclic Content (D3–D10 ≤ 300 ppm): Complies fully with stringent global environmental and health standards (such as EU REACH regulations regarding D4/D5/D6 thresholds). Minimizes potential regulatory restrictions on end products.

Exceptional Volatile Control (≤ 0.2%): Drastically reduces weight loss, shrinkage, and outgassing under high-temperature processing or long-term operational environments.

High-Purity Reactive Termini: Active silanol (–OH) groups ensure precise, highly efficient crosslinking behavior with alkoxy, acetoxy, oxime, or amine silane crosslinkers.

Outstanding Physical Properties: Delivers excellent thermal stability, moisture resistance, electrical insulation properties, and a wide service temperature range.

Eco-Friendly & Safe Formulation: Low odor, low toxicity, and enhanced biocompatibility render it highly suitable for applications in sensitive environments.

Applications:

High-End Sealants & Adhesives: Base polymer for manufacturing premium RTV (Room Temperature Vulcanizing) silicone sealants used in construction architectural glass walls, automotive gasketing, and cleanroom installations.

Electronics & Semiconductor Encapsulation : Used in potting compounds, thermal interface materials (TIMs), and gels where siloxane outgassing must be avoided to prevent contact failure or optical fogging.

Personal Care & Cosmetics Coatings : Acts as an intermediate or conditioning additive where low cyclic content is mandatory to meet consumer safety standards.

Textile & Leather Finishing: Formulated into premium softening agents, water repellents, and elastomeric finishes, ensuring no residual restricted cyclic materials remain on consumer fabrics.

Silicone Rubber Modification : Serves as an excellent structure control agent (anti-creping agent) in HTV (High Temperature Vulcanizing) silicone rubber processing to eliminate internal stress and improve transparency.
