Heat Stabilizer That Can Be Added To Tarpaulin Production

When tarpaulin manufacturers make tarpaulins, in order to enhance its use effect, they will add some additives, and heat stabilizer is one of the commonly used additives. However, what are the heat stabilizers that can be added?
1) Complex metal salt: a common type of heat stabilizer. It is usually sold as a preformed liquid, paste, or powder. Commonly used varieties are barium-cadmium, barium-calcium-zinc, barium-zinc, calcium-zinc and calcium-magnesium-tin-zinc fatty acid salts. This heat stabilizer is usually used in combination with organic additives (such as phosphites, epoxy compounds, polyols and phenolic antioxidants) to form composite heat stabilizers, which meet the requirements of different processing technologies and product applications.
2) Lead salt: one of the earlier applications of heat stabilizer. It has excellent long-term thermal stability, weather resistance and electrical insulation, but it affects the transparency of the product, is toxic, has initial coloring, is easy to vulcanize, and has poor compatibility and dispersion with polyvinyl chloride. Lead salts do not lubricate and should be used in combination with metal soap lubricants. Commonly used varieties include tribasic lead sulfate and dibasic lead phosphite. Used in the manufacture of opaque PVC sheets, pipes and wire and cable sheathing.
3) Special heat stabilizer: refers to some pure organic compounds with special effects, such as aminocrotonate used in alkaline emulsion polymerized PVC, pentaerythritol or dicyandiamide used in asbestos-filled PVC floor materials .
4) Organotin: These heat stabilizers are mainly used in various soft PVC products that require transparency. Commonly used varieties are maleates, thiolates and carboxylates. Among them, di-n-octyltin maleate can be used as a non-toxic stabilizer for food and drug packaging materials.
