PBAT-25D是一款硬度25D的熱塑性生物降解塑料，兼具PBA和PBT的特性。延展性、耐熱性、沖擊性和生物降解性能優(yōu)異，是生物降解塑料市場應(yīng)用廣泛的降解材料之一。在土壤或其他堆肥環(huán)境中，*終降解為二氧化碳和水，環(huán)境友好。主要應(yīng)用于：可降解包裝薄膜，可降解包裝袋（購物袋、垃圾袋、寵物糞便袋、電子產(chǎn)品包裝袋、食品包裝袋），可降解地膜，可降解涂層標簽等。
PBAT-25D is a thermoplastic biodegradable plastic with hardness of 25D, which has the characteristics of PBA and PBT. It has excellent ductility, heat resistance, impact and biodegradability. It is one of the widely used degradable materials in the biodegradable plastic market. In soil or other composting environment, it is finally degraded into carbon dioxide and water, which is friendly to environment. Mainly used in: degradable packaging film, degradable packaging bag (shopping bag, garbage bag, pet feces bag, electronic product packaging bag, food packaging bag), degradable plastic film, degradable coating label, etc.
