PP - V30G based on The the UnipolTM gas phase process technology of grace company to produce homopolymer polypropylene resin. The main raw material of the product is polymerization grade propylene, which is produced by polymerization, degassing, granulation, packaging and other processes with efficient catalyst
PP Injection V30G is a kind of polypropylene resin, mainly used for injection molding process, and has the advantages of high isotacticity, high fluidity and low ash content. The following is a detailed
introduction:
Product Characteristics
Good mechanical properties: The tensile yield stress is ≥32.0MPa, and the flexural modulus is ≥1300MPa. It has high impact strength, good acid and alkali corrosion resistance, excellent insulation performance, and can maintain good mechanical properties under different environmental conditions.
Excellent molding performance: It has good hot - melt fluidity, which is convenient for injection molding processing, can improve production efficiency, and can ensure the accuracy and surface quality of products. The product has low warpage and is easy to release from the mold, which helps to obtain high - quality molded products.
Other characteristics: The ash content is low, which is beneficial to improve the overall quality of the product; the yellow index is less than 4.0, which has a certain advantage in appearance color; the isotactic index is ≥95.5%, which affects the crystallization performance and physical properties of the resin.
Application Areas
Household items: It is suitable for manufacturing trays, plastic boxes, toys, trash cans, small daily necessities, etc. Due to its good
mechanical properties and molding performance, it can meet the use requirements of different household items and has a certain decorative effect.
Packaging materials: It can be used to produce food packaging boxes, etc. Its non - toxic and odorless characteristics meet the requirements of food packaging materials for safety and hygiene, and its good mechanical properties and barrier properties can protect the quality and safety of food.
Industrial parts: It has applications in the production of some industrial parts, such as parts of sports equipment and home appliances. It can meet the performance requirements of industrial parts for materials, such as strength, toughness and wear resistance.
Processing Conditions
Melting temperature: It is 220 - 275 °C, and it should be noted not to exceed 275 °C to avoid affecting the performance of the material due to excessive temperature.
Mold temperature: It is 40 - 80 °C, and 50 °C is recommended. The degree of crystallization of the product is mainly determined by the mold temperature, and a suitable mold temperature helps to improve the quality and performance of the product.
