Lead-Based or Calcium-Zinc-Based PVC Thermal Stabilizer for Producing Door and Window Profiles
Application:
PVC door and window profiles, PVC pipes and fittings, cable sheathing, foamed PVC sheets
Product Introduction:
Due to its structure, PVC is highly sensitive to temperature and cutting pressure and is easily destroyed. Degradation of PVC causes the release of hydrochloric acid gas and the catalytic effect will be degraded. Therefore, the destruction proceeds very quickly and creates large amounts of HCL gas, which is corrosive and toxic. So, Thermal stabilizers are used. According to the process conditions and formulations, these stabilizers will be different from each other. Most stabilizers contain metal elements that react with HCL and prevent further degradation.
These products can be divided into two general categories: lead-based stabilizers and calcium/zinc-based stabilizers.
In different applications, this package, which is a complete package of various additives, is provided in addition to stabilizers, internal and external lubricants, color and pigment, and process aids.
Technical Specifications:
The term «one pack» stabilizers is common for this product and indicates the existence of different implementation required by the formulation. Stabilizer packages include stabilizers, mineral fillers, softeners, lubricants, process aids, and special additives such as flame retardants. Stabilizer packages are used in most products to provide thermal stability and rheology behavior adjustment, and these materials should be changed according to the customer’s formulation. It is worth noting that these packages must be customized for different lines, so there are many product codes for each product category. Stabilizers act on the basis of neutralizing HCL gas and preventing the formation of double bonds in the polymer structure. It also prevents the oxidation of PVC and is replaced by unstable chlorine on PVC. The calcium/zinc stabilizers in this product are lead-free. Removing lead from the formulation as a heavy metal will result in a more reasonable price. One of the challenges of removing lead is the color of the product. Because lead in combination with PVC’s chlorine produces lead chloride, which creates a white color. With the removal of lead, this white color will no longer exist. Also, the removal of lead will change the water absorption and dynamic thermal stability properties. On the other hand, due to electronic issues, not every additive can be used.
