DHT-4A Acid Scavenger

DHT-4A is a hydrotalcite-like compound that has been developed as a stabilizer (halogen scavenger) for polyolefins and other plastics. DHT-4A is a high quality halogen scavenger for transparent films of polyolefins due to its low level of water carry over. It also has a refractive index which is close to that of polyolefins. When used with HALS, DHT-4A provides long term weatherability.
