Julong Jiarui offers a wide array of PP compounds designed for applications that require excellent chemical resistance, lightweight properties, and ease of processing. These plastic granules are available in multiple grades, including mineral-filled, glass fiber reinforced, and flame retardant variants, each engineered to meet specific mechanical and thermal demands. The mineral-filled PP grades provide enhanced stiffness and dimensional stability, making them ideal for automotive interior parts and appliance components. Glass fiber reinforced PP compounds deliver superior tensile strength and heat deflection temperatures for under-the-hood applications. Flame retardant PP formulations comply with UL94 standards, ensuring safety in electrical and electronic enclosures. For a complete overview of the PP product line, refer to thePP product introduction page, where detailed specifications and application guides are available.

The portfolio includes a full range of polyethylene granules, with a strong emphasis on high-density polyethylene (HDPE) grades that excel in rotomolding and blow molding processes. HDPE granules from Julong Jiarui are characterized by excellent impact resistance, stress crack resistance, and UV stability, making them suitable for outdoor tanks, marine buoys, and large industrial containers. The company supplies both natural and custom-colored HDPE compounds, allowing manufacturers to achieve desired aesthetics without secondary operations. In addition to HDPE, low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE) granules are available for film extrusion, injection molding, and pipe production. Each shipment of plastic granules is accompanied by a certificate of analysis confirming melt flow index, density, and mechanical properties, ensuring full traceability and consistency across batches.

For high-temperature and high-strength applications, Julong Jiarui produces PBT compounds that offer outstanding electrical insulation, dimensional stability, and chemical resistance. These plastic granules are reinforced with glass fibers up to 30% and can be formulated with flame retardant additives to meet demanding industry standards. Nylon (PA6 and PA66) compounds form another critical segment of the product range, providing exceptional wear resistance, toughness, and thermal stability for automotive engine components, power tools, and industrial gears. The company'snylon product introduction page provides detailed technical data on various reinforced and impact-modified grades. Additionally, Julong Jiarui supplies pvc granules and ABS compounds for specialized applications, ensuring that clients have access to a one-stop sourcing solution for their diverse material needs.

Rotational molding demands plastic granules with precise melt flow characteristics, excellent thermal stability, and uniform particle size to ensure even wall distribution and void-free finished products. Julong Jiarui's HDPE and LLDPE grades are specifically engineered to meet these requirements, delivering superior impact strength and warpage resistance for large, complex parts. The company works closely with rotomolders to develop custom formulations that optimize cycle times and reduce material waste. Typical rotomolding applications include water storage tanks, kayaks, playground equipment, and agricultural sprayer tanks, where durability and weather resistance are paramount. By leveraging the company'sPP product applications expertise, manufacturers can also explore hybrid material solutions that combine polypropylene's chemical resistance with rotational molding design flexibility.

Injection molding remains one of the most widely used processes for producing precision plastic parts, and Julong Jiarui's plastic granules are formulated to deliver consistent shrinkage, excellent flow, and rapid cycle times. The company's PBT, PA, and ABS compounds are particularly favored for automotive connectors, electronic housings, and structural components that require tight tolerances and long-term reliability. Each grade undergoes rigorous rheological testing to ensure predictable mold filling and minimal flash formation. For applications demanding enhanced surface finish, Julong Jiarui offers specialty grades with improved gloss and color stability. The company'sPBT product applications page showcases how these materials perform in demanding electrical and automotive environments, providing engineers with the confidence to specify Julong Jiarui compounds in critical designs.

Beyond rotomolding and injection molding, Julong Jiarui's plastic granules serve the extrusion market for producing pipes, profiles, sheets, and films. The company's HDPE and PP compounds are designed to maintain excellent melt strength and dimensional stability during continuous extrusion processes. Applications include corrugated drainage pipes, geomembranes, packaging films, and furniture profiles.
