热塑性生物降解塑料PBAT-25D技术说明
 Technical description of thermoplastic biodegradable plastic PBAT-25D


PBAT-25D是一款硬度25D的热塑性生物降解塑料,兼具PBA和PBT的特性。延展性、耐热性、冲击性和生物降解性能优异,是生物降解塑料市场应用广泛的降解材料之一。在土壤或其他堆肥环境中,*终降解为二氧化碳和水,环境友好。主要应用于:可降解包装薄膜,可降解包装袋(购物袋、垃圾袋、宠物粪便袋、电子产品包装袋、食品包装袋),可降解地膜,可降解涂层标签等。
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.
