يشير الراتنج عادةً إلى بوليمر عضوي له نطاق تليين أو انصهار بعد تسخينه، ويميل إلى التدفق تحت تأثير القوة الخارجية عند التليين، ويكون صلبًا وشبه صلبًا وفي بعض الأحيان سائلًا في درجة حرارة الغرفة. بشكل عام، يُسمى أي مركب بوليمر يمكن استخدامه كمادة خام لمعالجة المنتجات البلاستيكية بالراتنج.
مواد البوليمر الطبيعية
★ Chitosan: It has appropriate biocompatibility and degradation properties, can promote platelet adhesion and thrombosis, and is terrific for excellent types of wounds.
★ Collagen: Activates clotting factors, promotes blood clotting, and is biocompatible and biodegradable to beneficial aid wound healing.
★ Cross-linked starch microspheres: can promote blood clotting, manipulate bleeding, restriction the cost of bloodborne infection, and have no immune response and allergic reaction.
★ Gelatin sponge: Through platelet aggregation, activation of coagulation factors and bodily barriers, it can obtain hemostasis and can rapidly soak up blood.
★ Cellulose material: There are many types, such as medical absorbable hemostatic gauze, hemostatic sealant, etc., which are fantastic for one-of-a-kind sorts of wounds. It can take in blood, promote platelet aggregation and thrombosis, and gather hemostasis.
Synthetic polymer materials
★ Polyurethane: It has right plasticity and mechanical properties, can promote thrombosis, and is suitable for trauma with large-scale hemorrhage.
★ Polyacrylamide: Forms a hydrogel that can take in plasma, pay interest blood, promote platelet aggregation, and is excellent for visceral hemostasis
