PP fiber masterbatch is a special type of plastic masterbatch that combines the advantages of polypropylene (PP) and glass fiber (or other fiber materials), with high strength, high rigidity, good dimensional stability, and excellent heat resistance.

1、 Definition and Characteristics

Definition: PP fiber masterbatch is a plastic masterbatch prepared by melting and blending polypropylene with fiber materials such as glass fibers at high temperatures through a special process.

characteristic:

High strength and rigidity: Due to the addition of glass fiber, the tensile strength and bending strength of PP fiber masterbatch are significantly improved.

Good dimensional stability: Under high temperature and long-term low load conditions, PP fiber masterbatch will not deform, and the product has excellent dimensional stability.

Excellent heat resistance: PP fiber masterbatch has good heat resistance, high heat deformation temperature, and can maintain stable performance at higher temperatures.

2、 Application Fields

PP fiber masterbatch is widely used in multiple fields due to its excellent performance:

Automotive industry: used for manufacturing body parts, engine mounts, fuel tanks and other components to improve the durability and safety of automobiles.

In the field of electrical and electronics, it is used to manufacture electrical enclosures, electronic component brackets, cable sheaths, and other products. Its excellent flame retardant properties provide strong guarantees for the safety of electrical products.

Construction industry: used to manufacture components such as door and window frames, pipelines, insulation panels, etc., to improve the insulation performance and durability of buildings.

In the field of furniture, it has become an ideal material for manufacturing indoor and outdoor furniture due to its high strength, wear resistance, and ease of cleaning.

3、 Flame retardant performance

Some PP fiber masterbatch also added flame retardants, such as environmentally friendly bromine and antimony flame retardant systems, to give it a higher flame retardant rating. For example, the flame retardant level of certain PP fiber added flame retardant masterbatch (such as TPP model) can reach UL94V-0, which means they have excellent flame retardant performance in combustion testing, do not drip, and have extremely slow flame spread speed.

4、 Production process and quality control

Production process: The production process of PP fiber masterbatch includes steps such as raw material preparation, melt blending, fiber dispersion, extrusion molding, cooling and shaping. Among them, melt blending and fiber dispersion are key processes that require strict control of process parameters such as temperature, speed, and time to ensure product quality.

Quality control: Conduct strict inspections on incoming raw materials, including testing of appearance, size, performance, and other aspects. Real time monitoring of various process parameters and production data during the production process, timely detection and resolution of problems that arise during the production process. Conduct strict quality inspections on finished products to ensure they meet customer requirements and standards.

5、 Precautions and Storage Requirements

Attention: When using PP fiber masterbatch, the appropriate ratio and processing technology should be selected according to product requirements to ensure the performance and stability of the final product.

Storage requirements: PP fiber masterbatch should be stored in a dry and cool place, paying attention to moisture prevention and avoiding direct sunlight. Packaging usually uses paper plastic composite bags or plastic bags lined with polyethylene plastic inner bags to ensure the sealing and moisture resistance of the product.
