慧正資訊：近年來，熱塑性聚氨酯（TPU）作為一種兼具橡膠彈性和塑料加工性能的高分子材料，憑借其卓越的物理和化學特性，在多個領域得到了廣泛應用。金緯機械作為行業內的領軍企業，憑借其先進的TPU膜生產線和創新技術，為TPU膜的生產提供了強大的技術支持。
1、TPU原料介紹
TPU（熱塑性聚氨酯）是一種兼具橡膠彈性與塑料加工性能的高分子材料，分為聚酯和聚醚兩大類型。同時具備以下特性：
• 環保無毒：可回收利用，符合歐盟 RoHS、REACH 等環保標準；
• 卓越彈性：斷裂伸長率高達 500%-800%，耐反復拉伸；
• 耐磨抗腐蝕：耐磨性能是天然橡膠的 3-5 倍；
• 寬溫域適應性：使用溫度范圍 - 40℃至 120℃。
Introduction to TPU Raw Materials
TPU (Thermoplastic Polyurethane) is a kind of polymer material that combines the elasticity of rubber and the processing performance of plastics. It is divided into two major types: polyester and polyether. It also has the following characteristics:
• Environmentally friendly and non-toxic: It can be recycled and meets environmental protection standards such as RoHS and REACH in the European Union.
• Excellent elasticity: The elongation at break is as high as 500%-800%, and it is resistant to repeated stretching.
• Abrasion resistance and corrosion resistance: The abrasion resistance is 3-5 times that of natural rubber.
• Wide temperature range adaptability: The operating temperature range is from -40°C to 120°C.
2、TPU 膜的核心優勢：不止于 “膜”
彈性與柔韌性：適用于動態環境（如運動裝備、醫療器械）；
防水透氣：微孔結構實現水汽交換，用于戶外服裝、鞋材；
耐候性強：抗紫外線、耐黃變，延長產品壽命；
粘接性佳：與金屬、布料、塑料等基材附著力優異。
Core Advantages of TPU Film: More Than Just a "Film"
Elasticity and flexibility: Suitable for dynamic environments (such as sports equipment, medical devices).
Waterproof and breathable: The microporous structure enables water vapor exchange, and it is used in outdoor clothing and footwear materials.
Strong weather resistance: It is resistant to ultraviolet rays and yellowing, extending the product's lifespan.
Good adhesion: It has excellent adhesion to substrates such as metals, fabrics, and plastics.
