CAB resin, full name Cellulose Acetate Butyrate, is not only popular in the coating and ink industries, but also has a place in the plastics industry.
1. Basic properties of Cellulose Acetate Butyrate
Cellulose Acetate Butyrate is made from cellulose by esterification with acetic acid and butyrate. This resin has excellent transparency, weather resistance and processing properties. Its chemical structure gives it good oil resistance, water resistance and chemical resistance, and it is also compatible with a variety of plastics and additives. These characteristics make CAB resin have a wide range of application prospects in the plastics industry.
2. Application of Cellulose Acetate Butyrate in Plastic Products
2.1 Transparent Plastic Products
CAB resin has extremely high transparency, almost comparable to glass. Therefore, it is often used to manufacture plastic products that require high transparency, such as eyeglass frames, optical lenses, transparent packaging boxes, etc. These products are not only beautiful in appearance, but also effectively protect the internal items from the influence of the external environment.
2.2 Weather-resistant plastic products
Due to its excellent weather resistance, CAB resin is often used in the manufacture of outdoor plastic products. For example, outdoor furniture, auto parts, building decoration materials, etc. These products can still maintain good performance and appearance in the environment of long-term exposure to sunlight, rain and wind and sand.
2.3 Chemical-resistant plastic products
The chemical resistance of CAB resin makes it perform well in the manufacture of plastic products that need to contact chemicals. For example, laboratory utensils, chemical containers, pipes and valves, etc. These products will not corrode or deform due to contact with chemicals during use, ensuring the safety and reliability of use.
2.4 Plasticity plastic products
CAB resin has good plasticity and can be made into plastic products of various shapes through various processing methods such as injection molding, extrusion, and blow molding. For example, toys, daily necessities, electronic equipment housings, etc. These products are not only beautiful in appearance, but also meet the needs of different users.
3. Advantages of Cellulose Acetate Butyrate
3.1 Environmental protection
CAB resin is a biodegradable material and is environmentally friendly. With the increasing awareness of environmental protection, more and more plastic products are beginning to use CAB resin to reduce pollution to the environment.
3.2 Processing performance
CAB resin has excellent processing performance and can be processed at a lower temperature to save energy. At the same time, it has good fluidity and is easy to mold, and can produce high-quality plastic products.
3.3 Versatility
CAB resin can not only be used alone, but also blended with other plastic materials to improve its performance. For example, blending with polycarbonate (PC) can improve its impact resistance, and blending with polypropylene (PP) can improve its heat resistance.
In general, Cellulose Acetate Butyrate has a very good performance in the plastics industry.
