PBS High Strength — Polybutylene Succinate, High Strength Grade AA
PBS High Strength Grade AA is engineered to provide improved mechanical performance over standard PBS grades. This modification increases its suitability for applications where higher rigidity and tensile strength are required, such as certain molded components or thicker-walled packaging, while retaining biodegradability.
