General Market Information:

In the PVC (Polyvinyl Chloride) compounding market, HALS, UV absorbers and optical brighteners are used. PVC is a popular thermoplastic polymer used in various applications, including building materials, pipes, cables, and packaging. However, PVC is susceptible to UV degradation, which can cause discoloration, cracking, and degradation of mechanical properties.

HALS, or Hindered Amine Light Stabilizers, are used to protect plastics from degradation caused by exposure to light and heat. They work by scavenging free radicals and other reactive species that can cause the degradation of polymers, thus protecting the material from degradation and maintaining its mechanical and optical properties over time.

UV absorbers are used in PVC compounding to protect the polymer from the harmful effects of UV radiation. They work by absorbing UV radiation and converting it into heat, thereby preventing the radiation from reaching the PVC and causing degradation. UV absorbers used in PVC compounding are typically organic compounds that are added to the PVC during compounding.

Optical brighteners, also known as fluorescent whitening agents, are added to PVC compounds to improve their appearance. They work by absorbing UV light and re-emitting it as visible blue light, making the PVC appear whiter and brighter. Optical brighteners used in PVC compounding are typically sulfonated compounds that are added in small quantities to the PVC compound.

Overall, the use of HALS, UV absorbers and optical brighteners in PVC compounding helps to improve the appearance and durability of PVC products, making them more suitable for outdoor applications.
