LF-PV11 Phenylvinyl Silicone Oil | High Refractive Index

Technical Specifications

PARAMETER	VALUE / RANGE
Appearance	Colorless transparent liquid

Product Description

Special Features of Phenylvinyl Silicone Oil LF-PV11:

High Refractive Index: A higher phenyl content correlates with a higher refractive index (typically ranging from 1.43 to 1.53), which significantly enhances the light transmission and optical clarity of final products;

Reactive Groups: The molecular structure features vinyl groups on chain ends or side chains. These facilitate addition reactions with hydride crosslinkers under platinum catalysis to form elastomers or rigid resins;

Excellent Stability: The incorporation of phenyl groups endows the material with exceptional resistance to high and low temperature extremes, radiation resistance, and self-extinguishing properties;

Superior Compatibility: Compared to standard vinyl silicone fluids, this material offers superior compatibility with organic resins and various fillers.

Packaging & Handling

In 25kg and 200kg drum.

Keep in cool, dry and ventilated place. Keep away from sunlight and fire sources. Keep in unopened containers, shelf life is 12 months from the date of production. Storage beyond the shelf life does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
