REAPAK B-AV/111
A lead phosphite-based stabilizer designed for the extrusion of window profiles. It contains technological additives.
Lead stabilizers
PVC lead stabilizers are effective additives based on lead compounds that provide high thermal stability of PVC compositions during production and operation, excellent electrical insulation properties and weather resistance.
More
For many years, they have been the main and economical “workhorses” in the PVC industry, providing products with high durability.
However, due to the toxicity of lead and stricter environmental laws, the consumption of this class of stabilizers is decreasing in most countries of the world, including Russia, and in Europe it is completely prohibited.
Main types and components
Lead salts are used as lead stabilizers, either individually or in a mixture (see below), as well as more convenient complex “single–package” systems that also contain the necessary lubricants and other additives.
- Lead Tribasic Sulfate (TOCS): The most common primary stabilizer that provides high temperature resistance.
- Lead stearates (dibasic- DOSS and neutral – HCC): They combine the functions of stabilizer and external lubrication. They form synergistic mixtures with TOC.
- Dibasic lead phosphite (DOFS): is used to increase the light fastness and weather resistance of products.
- Lead phthalate: is used in the manufacture of cable insulation due to its excellent dielectric properties.
Advantages (advantages)
Lead stabilizing systems make it possible to process compositions at high temperatures (up to 210 °C for rigid PVC) and ensure the durability of products using them.
- High thermal stability: Effectively neutralize hydrogen chloride released when PVC is heated, slowing down polymer degradation.
- Electrical insulation: They have excellent dielectric characteristics, which is valuable for cable products.
- Durability: They provide high weather and light resistance, which is critical for building profiles.
- Cost-effectiveness: They are one of the cheapest stabilizers.
Application
Lead stabilizers can be used in the production of both rigid and plasticized PVC products by various methods.
- Pipes and fittings: Water supply and sewerage systems.
- Window and door profiles: They ensure the preservation of color and physico-mechanical characteristics during long-term outdoor operation.
- Sheet materials: Panels, window sills, and monolithic and foamed sheets.
- Cable and conductor products: Insulation and cable sheaths.
