About Yuyao Best Plastics Industry Co., Ltd.
Yuyao Best Plastics Industry Co., Ltd. is located in Yuyao China Plastic City, the largest and most professional plastic trading center in China. We are a full‑service supplier focused on modified engineering plastic pellets and custom‑formulated color masterbatch. Rooted in China's core plastics industry supply chain, we provide cost-effective and stable quality one-stop plastic raw material solutions for customers around the world.
Built on years of hands‑on industry know‑how and extensive market resources, our business covers two core product lines to meet diverse production and sourcing requirements for plastic suppliers.
1. Modified Engineering Plastic Pellets
We supply a full range of modified engineering plastics, including reinforced, toughened, flame-retardant, weather-resistant, and high temperature grades LCP, PA6, PA66 and PPS. Our materials serve a broad spectrum of sectors: electronics and electrical components, automotive parts, kitchen‑bath hardware, mechanical engineering, power‑energy systems, power tools, medical devices, aerospace and telecommunication hardware. In addition to conventional standard grades of raw materials, we can customize modified formulations according to customer product performance requirements, ensuring stable batch quality and controllable and reliable physical performance parameters.
2. Color Masterbatch
We supply premium‑grade general‑purpose and application‑specific color masterbatch. Includes solid‑color masterbatch, black & white masterbatch, plus functional masterbatch variants: anti‑UV, anti‑aging, flame‑retardant and antibacterial grades.
Compatible plastics list: PE, PP, PC, PA, ABS, AS, HIPS, GPPS, PET, PMMA, PBT, POM, EVA, TPU, TPE, PVC and more.
Key product benefits: High pigment loading, excellent dispersion, zero visible color deviation, high heat resistance and full environmental compliance. Well‑suited for injection molding, extrusion and blow‑molding processes. Works reliably across multiple polymer substrates to deliver uniform color and stable finished‑part quality.
Our masterbatch solutions are widely adopted across: packaging containers, consumer daily goods, cosmetic packaging, home appliances & electronics, construction materials, telecommunications, agriculture, gardening equipment, office supplies, new‑energy components, automotive parts, medical consumables, power tools, toys, pet products, kitchenware and logistics products.
All our products hold mainstream international certifications: SGS, RoHS, REACH, FDA, UL, ISO9001 and ISO14001.
We operate under core business principles: integrity driven operation, quality priority, customer centric service and mutually beneficial partnership. A strict raw material screening and end‑to‑end quality control system runs through our whole workflow.

Frequently Asked Questions About Best Plastics
The 6 most common questions from buyers
Is Yuyao Best Plastics Industry Co., Ltd. a factory or a trader?
We are a comprehensive supplier based in Yuyao China Plastic City: modified engineering plastics are custom-compounded and distributed through long-term partner upstream compounding plants (twin-screw lines, full testing equipment), and color masterbatch is likewise supplied under a factory system. We handle unified quality control, quoting and after-sales, combining factory-direct pricing with a trader's multi-brand stock capability.
What products does Best Plastics supply?
Two product lines: modified engineering plastics — glass-fiber reinforced, toughened, flame-retardant, weather-resistant and high-temperature grades of PPS, PA66, PA6 and LCP, with 41 standard grades in stock; and color masterbatch — black & white, color and functional masterbatch (anti-UV, flame-retardant, filler, anti-static) covering 18+ substrates including PE/PP/ABS/PA/PC/PVC, with custom Pantone color matching supported.
Which certifications do Best Plastics products hold?
Our products are certified to seven international standards: SGS, RoHS, REACH, FDA, UL, ISO9001 and ISO14001. Routine batches ship with COA; export orders can be accompanied by RoHS/REACH reports and MSDS.
How do sampling and small-batch orders work?
Send us the application, performance requirements, target color and monthly volume, and we reply with an equivalent grade or color formula within 2 hours. Standard grades ship samples in 3-5 working days; custom color sampling is free with 2-5 working days turnaround. In-stock masterbatch starts from 25kg — validate in small batches first, then scale up.
Can you replace our current imported grades?
Yes. Provide the current grade datasheet and operating conditions (temperature, load, media, FR rating) and we sample equivalent grades and validate same-mold comparison testing. We have extensive PPS/PA66 import-substitution cases, typically saving 15%-40%.
What are the lead times and logistics arrangements?
Standard grades are in ample stock — orders placed today ship the same day; custom grades take 5-15 days. We are about 2 hours from Shanghai, ship nationwide via the Yangtze River Delta logistics network, and export through Ningbo/Shanghai ports, typically FOB.
