LS-CHTS Cyclohexyltrimethoxysilane
CAS NO.: 17865-54-2

Name: LS-CHTS Cyclohexyltrimethoxysilane
Brand: Nanjing Silfluo New Material Co., Ltd.
Availability: InStock

Silfluo LS-CHTS is Cyclohexyltrimethoxysilane, a trifunctional cycloalkyl-functional trimethoxysilane.

The molecule contains one cyclohexyl group and three hydrolyzable methoxy groups on silicon.

The bulky cyclohexyl group provides steric coordination with active sites in MgCl₂-supported Ziegler-Natta catalyst systems, functioning as an external electron donor (selectivity control agent).

Used primarily as external electron donor in Ziegler-Natta propylene polymerization catalyst systems for isotactic polypropylene production.

Applications of LS-CHTS Cyclohexyltrimethoxysilane

1. Polypropylene (PP) polymerization — external electron donor

Used as external electron donor in MgCl₂-supported Ziegler-Natta catalyst systems for isotactic polypropylene production.

2. Ziegler-Natta catalyst formulation

Used in catalyst preparation and performance tuning for custom Ziegler-Natta systems in propylene polymerization processes.

Packing of LS-CHTS Cyclohexyltrimethoxysilane

Available in 20kg pails, 180kg drums.

Safety and Storage of LS-CHTS Cyclohexyltrimethoxysilane

Store under nitrogen in a cool, dry, well-ventilated place away from direct sunlight, heat, and ignition sources. Keep containers hermetically sealed.

Reacts with atmospheric moisture; hydrolysis releases methanol and forms silicone gel. Maintain dry, inert atmosphere during all handling and transfer operations.

Avoid contact with strong acids, alkalis, and oxidizing agents.

Shelf life: 12 months minimum from manufacture date in original unopened containers under nitrogen protection.
