The factory has an annual production capacity of up to 25,000 tons and can reliably fulfill large-volume orders.

Is it a factory of origin? Can you conduct a factory audit?

We have our own production lines, in-house laboratories, and independent formula development—no middlemen. We offer customers factory inspections via video, on-site audits, and remote compliance reviews.

What are your main modified plastic materials?

Modified PMMA/ASA, modified PMMA, modified ASA, modified PC, modified PC/ABS alloy, modified ABS, modified PP, modified PPO, modified PPS, nylon modification, polyester modification.

In which industries are these materials primarily used?

New energy vehicles, smart home appliances, consumer electronics, robots, drones, power tools, photovoltaics, and more.

Can it replace imported materials?

Certainly. Our formulations are benchmarked against those of Covestro, BASF, EMS-GRIVORY, INEOS, and other leading materials suppliers, delivering stable performance and excellent batch-to-batch consistency. They can fully replace imported materials, significantly reducing customers’ costs.

Does the product comply with environmental export standards?

All products comply with RoHS, REACH, and PFAS environmental standards and can be accompanied by official CNAS test reports and compliance certificates.

What patented technologies does the company possess?

We hold multiple patented formulations—covering flame retardancy, hydrolysis resistance, low VOCs, and high‑toughness modification—and have achieved end-to-end control over both formulation development and manufacturing processes, ensuring product stability and distinctive competitive advantages.

What foreign trade documents can be provided?

We can provide: TDS material safety data sheets, COA factory‑issued quality inspection reports, CNAS test reports, RoHS/REACH certificates, certificates of origin, invoices, packing lists, patent certificates, and corporate qualification documents—fully meeting all requirements for overseas customs clearance, factory audits, and platform onboarding.

Is it possible to get a free sample?

Mainland China: Samples weighing 25–50 kg are provided upon customer request; for other regions, shipping costs are borne by the customer, while the sample itself is free of charge.

Does it support formula customization?

We can provide precision‑tailored modification services based on customers’ material specifications, including enhancements to system performance and aesthetic optimization, flame‑retardancy grade adjustment, toughening for improved high‑ and low‑temperature resistance, hydrolysis resistance, low odor and low VOC levels, UV resistance and weatherability, color matching and surface‑finish tuning, reduction of product warpage, formulation of light‑diffusing materials with tailored transmittance and haze, as well as the development of high‑flow, precision injection‑molding compounds.

What is the minimum order quantity (MOQ)?

Minimum order quantity: 300 kg

How long is the delivery lead time?

Within mainland China: 10–15 days after order placement; for other regions: 21–40 days, depending on the destination.

How can batch-to-batch consistency be ensured?

We implement standardized raw-material screening and equip our facilities with three of the industry’s most advanced extrusion systems: Coperion, Leistritz, and Krauss Maffei. Our production lines are fitted with five gravimetric batch feeders and MIXACO high‑shear mixers, integrated with a customized MES to enable digital management of ingredient batching and end-to-end quality data traceability. Complemented by frequent in‑process inspections and comprehensive factory‑level quality checks, we rigorously control every stage of the manufacturing process—from incoming materials to finished‑product shipment—ensuring consistent product quality and eliminating batch‑to‑batch variability.

What shipping methods are supported?

Mainland China: Full truckload, less-than-truckload, and dedicated‑line logistics. Other regions: Ocean freight (FCL/LCL), air freight, China–Europe Railway Express, Russia‑specific services, and overseas warehouse delivery, with end-to‑end logistics solutions available.

Do you provide injection molding technical guidance?

Our company offers comprehensive technical support. With a deep understanding of our customers’ real-world application needs, we have assembled a dedicated team of technical experts capable of swiftly resolving a wide range of molding and surface‑appearance issues encountered during material processing. In addition, we can engage early in the product development phase, collaborating on structural design, material selection, and evaluation, thereby providing end-to-end technical support to our clients.

How should quality issues be handled?

All products undergo a full factory inspection, resulting in an extremely low incidence of quality issues. Should any batch exhibit non‑conforming physical properties, color variations, or impurities, we offer unconditional after‑sales service, including exchanges, replacements, or mutually agreed‑upon solutions.

How can we establish long-term cooperation?

Eligible for long-term distributor pricing, dedicated technical support, priority access to new‑product samples, guaranteed production capacity, and expedited after‑sales service, we provide customers with a stable, cost‑effective, high‑value‑for‑money supply chain for modified plastics.

How can I obtain a quote and samples?

You can submit a sample request on our official website, or contact our sales manager via email or phone to specify the material type, intended application, and any special requirements (such as flame retardancy, toughening, temperature resistance, or color), along with your order quantity. We will promptly provide you with an accurate quotation, TDS documentation, and a sample‑testing plan.
