Lead Distearate CAS 1072-35-1

Lead Distearate (CAS 1072-35-1) is a metallic soap derived from stearic acid, widely used in rigid PVC formulations as a heat stabilizer and internal/external lubricant. It plays a functional role in improving thermal stability during processing while supporting melt flow and surface finish in extrusion and molding operations.

In industrial supply, Lead Distearate is typically provided as a solid material in powder or flake form, suitable for direct incorporation into PVC dry blends or compound formulations. Standard export packaging is available, with supporting documents such as COA, TDS, and SDS provided for procurement and regulatory handling.

Typical Applications

PVC heat stabilizer: Used in rigid PVC formulations to improve thermal stability during extrusion, calendaring, and molding processes.
Lubricant in plastics processing: Functions as both internal and external lubricant, enhancing melt flow and reducing equipment adhesion.
Cable and pipe compounds: Applied in PVC compounds for cables, pipes, and profiles where thermal processing stability is required.
Processing aid in polymer compounding: Helps maintain processing consistency and surface quality in PVC-based systems.

Packaging

Lead Distearate is supplied as a solid material and is typically packed in moisture-resistant bags with inner lining or in fiber drums suitable for powder or flake chemicals. Packaging is designed to minimize dust generation and prevent contamination during handling and transport.

For export shipments, materials are packed to maintain stability and handling safety during long-distance transport. Packaging formats can be adjusted depending on order volume and customer handling requirements.

Storage

Store in a cool, dry, and well-ventilated environment. Keep containers tightly sealed to prevent moisture absorption and contamination. Avoid exposure to direct sunlight and sources of heat. Proper handling procedures should be followed due to the presence of lead compounds.
