1. How to use pp toughening agent
Toughening agent is an additive used to increase the toughness of plastics. pp toughening agent is a commonly used toughening agent and is suitable for It is used in the modification processing of various polypropylene and has the characteristics of small addition amount and low cost. So how to use pp toughening agent?
1. Determine the amount of additives. The addition ratio of pp toughening agent is generally 5% to 10%. Weigh the appropriate amount of pp toughening agent according to the amount of raw materials.
2. Mix the pp toughening agent and plastic powder evenly in a ratio of 1:4, then add it to the plastic particles or powder mixture (be careful not to add melted plastic), and stir thoroughly. Mix evenly until there are no lumps.
3. Pour the material into the extruder die for granulation or injection molding.
In addition, the pp toughening agent can also be added directly to the pp masterbatch and stirred evenly before use.
2. What should you pay attention to when using toughening agents
When using toughening agents, pay attention to the following points:
1. The dosage of toughening agents must be determined. Different types of toughening agents have different addition ratios. They should be added as needed to avoid Add more or less.
2. To ensure product quality and performance, please control the temperature and speed.
3. When the toughening agent is added to the plastic, it is strictly forbidden to mix metal impurities.
4. When using granular toughening agent to mix, pay attention to the centrifugal force during mixing, and mix slowly.
5. There are many types of toughening agents, which should be selected according to the type of resin and the purpose of the adhesive. Compatibility issues must be considered after adding some toughening agents.
6. After adding the toughening agent, the toughening effect of the toughening agent can be tested 24 hours after extrusion, injection molding or blow molding. If the effect is not satisfactory, the toughening agent can be replaced.
