Company Profile

Shanghang Xinchanglong Industrial Co., Ltd., founded in 1996, is a professional manufacturer of plastic impact modifiers and functional additives, specializing in recycled plastic modification and pelletizing solutions.

With large-scale stable production, strict batch quality control with COA, ISO certifications, and an experienced R&D team, we provide cost-effective, customized formulations for ABS, HIPS, PA, PC, PS, PE, and PP applications. We support small-quantity sampling, fast technical response within 24-48 hours, flexible trade terms, and long-term cooperation worldwide.

Shanghang Xinchanglong Industrial Co., Ltd. was established in 1996 and is a professional manufacturer and solution provider of plastic modification additives, with more than 20 years of industry experience.

We operate large-scale and stable production facilities at our manufacturing base in Fujian, China, supported by multiple production lines, while our headquarters is located in Shenzhen, Guangdong, enabling efficient coordination, fast delivery, and reliable global service.

Xinchanglong focuses on plastic impact modifiers and functional additives, with particular expertise in recycled plastic pelletizing and modification. Our main products include Impact Modifiers (for ABS, HIPS, PA, PC, PS, PE, PP), Compatibilizers (such as MAH-grafted grades), and MFI Modifiers, designed to enhance toughness, processing performance, and cost efficiency.

Unlike ordinary additive suppliers, we operate our own recycled plastic pelletizing plants, allowing us to deeply understand real production conditions and customer pain points. With an experienced in-house R&D team and patented technologies, we provide customized formulation solutions based on customers' raw materials, equipment, and cost targets-helping clients reduce overall modification costs by at least 20% through low addition levels, precise cost control, and stable performance.

Quality consistency is one of our core strengths. All products undergo strict incoming inspection, in-process control, and batch-by-batch quality testing, with final inspection before shipment. A Certificate of Analysis (COA) is issued for each batch to ensure consistent quality and long-term production stability.

Our products are widely applied in recycled and virgin plastics, including ABS, HIPS, PA, PC, PS, PE, PP, glass-fiber reinforced nylon, low-smoke halogen-free materials, and polymer alloys, serving industries such as automotive parts, electrical appliance housings, outdoor products, containers, pipes, films, and industrial components.

Xinchanglong is certified with ISO 9001, ISO 14001, ISO 45001, and our products comply with RoHS and REACH standards. We also provide TDS, MSDS, sea transport safety reports, and full technical documentation to support global customers.

Committed to environmental protection, recycling, carbon reduction, and low-carbon sustainability, we continuously develop environmentally friendly modification solutions that support circular economy applications.

In addition to plastic modification additives, we also supply a separate product series for the optical cable industry, including chemical auxiliaries, cable filling compounds, glass yarn, and water-blocking yarn, offering diversified material solutions across industries.

We support customized formulations, long-term technical cooperation, and after-sales technical support, with technical feedback typically provided within 24-48 hours. Small-quantity samples (1-3 kg) are available for testing. We accept EXW, FOB, CFR, CIF terms, offer tiered pricing based on order volume, have no minimum order quantity, and can provide optimized logistics solutions.

Our products are exported to Malaysia, Indonesia, Vietnam, Thailand, Japan, South Korea, Bangladesh, Turkey, Iran, India, Brazil, Russia, and other global markets. Xinchanglong is committed to being a reliable, long-term technical partner for customers worldwide.
