PP modified plastics refer to plastic particles that have been functionally modified from polypropylene (PP) raw materials. Through various processing methods such as filling, blending, reinforcement, flame retardancy and weather resistance, these plastic particles are improved to meet some performance requirements that PP raw materials cannot achieve during the production process. The modification process is carried out entirely according to actual application needs, aiming to improve the performance of the product and meet the use requirements in various complex environments.
The main modification methods of PP modified plastics include: Filling: Enhance the mechanical properties of the material by adding glass fiber, carbon fiber or other inorganic powders. Blending: Blending with other plastics or elastomers to improve its processing performance or reduce costs. Reinforcement: Improve the strength and rigidity of the material by adding reinforcing materials (such as glass fiber). Flame retardant: Add flame retardants to improve the fire resistance of the material. Weather resistance: Add UV inhibitors and other stabilizers to extend the service life of the material
PP modified plastics are widely used in many fields:
Automotive industry: PP modified materials are widely used in the automotive field, mainly for automotive interior and exterior trims. For example, reinforced modified PP materials (such as glass fiber reinforced) are used to improve the strength and heat resistance of automotive parts, and are suitable for automotive structural parts and interior trims. In addition, high-flow, spray-free modified PP materials are also used for automotive interior and exterior trims, such as dashboards, steering wheels, bumpers, etc.
Electronic appliances: Used to manufacture home appliance housings, wire and cable insulation layers, etc., due to its good electrical properties and processing properties
Packaging industry: Used to manufacture plastic bags, containers, etc., due to its good transparency and toughness
Construction industry: Used to manufacture pipes, plates, etc., due to its good chemical resistance and processing properties
Performance characteristics
Compared with ordinary plastics, PP (GF30/45 )modified plastics have the following significant advantages:
Strength and rigidity: The modified PP plastics have excellent strength, rigidity and hardness, and can work stably at high temperatures
Heat resistance: It has good heat resistance and can work stably at a high temperature of 100°C
Chemical stability: It is not affected by humidity and has good chemical stability
Lightweight: The density is between 89-91g/cm³, which is the leader of lightweight varieties of plastics
Environmental protection: Non-toxic, tasteless, odorless, with good degradability, reducing the impact of white pollution on the environment
