What Is The Difference Between The Color Powder In The Rotational Molding Process And The Color Powder In Other Processes?
Compared with toners from other processes, there are significant differences between the toners produced by the rotational molding process. These differences are mainly reflected in the following aspects:
1. Main materials
Rotational molding toner: usually made of polyethylene (PE), polypropylene (PP) and other materials.
Other process toners (such as injection toners): may be made of PVC, ABS and other plastics.
2. Production process
Rotational molding toner: Its production usually involves mixing the pigment and resin through physical friction, high-speed rotation, etc., so that the pigment is evenly dispersed in the resin.
Other process toners (such as injection molding toners): usually made by dissolving the pigment in a solvent, mixing it evenly with the resin and then drying it to form a powder.
3. Performance characteristics
Rotational molding toner: It has good weather resistance, gloss and waterproofness. These characteristics make rotational molding toner widely used in the manufacturing of outdoor products and daily necessities.
Other process toners (such as injection molding toners): Their performance characteristics may be more focused on internal product applications, such as electronics, electrical appliances, toys and other industries.
4. Scope of use
Rotational molding toner: Due to its good weather resistance and waterproof properties, it is suitable for the manufacture of outdoor products such as furniture, trash cans, water tanks, etc.
Other process toners (such as injection molding toners): are more suitable for coloring internal products, such as electronic product casings, toys, etc.
5. Price
Rotational molding toner: Since the raw materials are relatively cheap and the production cost is low, the price is more favorable than other process toners (such as injection molding toner).
6. How to use
Rotational molding toner: usually painted or mixed on the surface of plastic products for color mixing.
Other process toners (such as injection molding toners) are directly injected through an injection molding machine to color the inside of plastic products.
To sum up, there are obvious differences between toners produced by the rotational molding process and toners produced by other processes in terms of main materials, production processes, performance characteristics, scope of use, price and usage methods. These differences enable toners of different processes to meet the needs of different fields and products.
