About Coace Chemical Company Limited - Plastic Raw Materials Supplier in China

Coace Chemical Company Limited is based in China and lists five distinct chemical products in its current catalogue. The company classifies its offerings under three top categories: Plastic Raw Materials, Industrial Chemicals, and Chemicals & Allied Products. The listed products include a coupling agent for polyethylene composites, polyamide (PA6/PA66) impact modifiers, a toughening agent for PA6/PA66, a polypropylene coupling agent, and a styrene‑maleic anhydride (SMA) copolymer. Each entry is recorded without additional sub‑variants, reflecting a focused portfolio of specialty additives used in polymer processing. The supplier’s catalogue does not provide HS codes, so trade classification must rely on standard HS headings for polymer additives and specialty chemicals.

The product set targets manufacturers that process engineering plastics, where functional additives improve adhesion, impact resistance, and melt flow characteristics. For example, the PE coupling agent is intended to enhance filler dispersion in polyethylene composites, while the PA6/PA66 modifiers aim to raise notched impact strength in nylon applications. The PP coupling agent serves similar adhesion functions for polypropylene blends, and the SMA resin is commonly used as a compatibilizer in polymer blends. All five items are positioned within the broader market of chemical additives that support high‑performance plastic manufacturing.

Product Range and Specialties of Coace Chemical Company Limited

The catalogue lists five specialty additive types: a polyethylene coupling agent, polyamide impact modifiers (PA6 and PA66), a PA6/PA66 toughening agent, a polypropylene coupling agent, and a styrene‑maleic anhydride (SMA) copolymer. In the plastics industry, coupling agents typically contain grafted maleic anhydride or similar functional groups to promote interfacial bonding between polyolefins and reinforcing fillers. Impact modifiers for PA6/PA66 are often graded by melt flow index (MFI) ranges such as 5‑15 g/10 min and impact energy values measured by Izod or Charpy tests (e.g., >30 kJ/m²). Toughening agents may be supplied as masterbatches with defined loading levels (e.g., 5 wt % to 20 wt %). SMA grades are identified by molecular weight (e.g., SMA 1200) and anhydride content (typically 9‑12 %). Polypropylene coupling agents follow similar functional chemistries, with performance specifications that include graft level (e.g., 0.5‑2 wt % maleic anhydride) and melt viscosity compatibility. These industry benchmarks help buyers compare the listed items against common performance criteria.

The products fall under the broader chemical additive market, where buyers look for consistent batch‑to‑batch properties, thermal stability, and compatibility with standard processing equipment. Typical packaging for such additives includes 25 kg bulk bags, 200 kg drums, or 1 ton polyethylene bulk containers, depending on order size. Specification sheets usually list parameters such as density, melt flow index, anhydride content, and impact strength, which are critical for formulation engineers.

Trade and Export Information - Coace Chemical Company Limited

Chinese exporters of polymer additives commonly serve customers in Southeast Asia, Europe, and North America, where automotive, consumer goods, and packaging sectors demand performance‑enhancing chemicals. The HS chapters most frequently applied to these goods are Chapter 38 (Chemical products) and Chapter 39 (Plastics and articles thereof). Buyers typically require compliance with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) for the EU market and may request ISO 9001 quality management certification or specific product safety data. Shipping from China often uses FOB Shanghai or Ningbo, with bulk shipments in 20‑ft or 40‑ft containers; alternative CIF terms are also standard. Export documentation generally includes a commercial invoice, packing list, certificate of origin, and a safety data sheet (SDS) that meets the Globally Harmonized System (GHS) labeling requirements.

The Chinese chemical export environment emphasizes consistent product testing, third‑party laboratory validation, and traceability of raw material sources. Importers generally look for test reports covering melt flow index, impact energy, thermal degradation temperature, and moisture content. For SMA and other anhydride‑based resins, compliance with RoHS (Restriction of Hazardous Substances) may be verified, especially for electronics‑related applications. Packaging is typically moisture‑controlled, with inner liners for bulk bags to prevent degradation during transit.

Sourcing from Coace Chemical Company Limited - Buyer Guidance

When sourcing from Coace Chemical Company Limited, buyers should request a detailed technical data sheet for each additive, confirming parameters such as melt flow index, anhydride graft level, impact strength, and thermal stability. A safety data sheet (SDS) compliant with GHS must be obtained to assess handling, storage, and transport requirements. Buyers are advised to verify REACH registration status for EU shipments and to ask for any available third‑party test reports that demonstrate compliance with the cited performance specifications.

Before confirming an order, verify the packaging format (e.g., 25 kg bag, 200 kg drum) matches the intended logistics plan, and request a sample batch for laboratory evaluation. Clarify the supplier’s standard lead time, which for specialty additives typically ranges from 30 to 45 days after receipt of a purchase order, and confirm the preferred Incoterm (FOB Shanghai is common). Documentation such as a certificate of analysis (CoA) accompanying each shipment helps ensure batch consistency.

What types of polymer coupling agents does Coace Chemical Company Limited offer?

The catalogue lists a polyethylene coupling agent and a polypropylene coupling agent, both designed to improve filler adhesion in their respective polyolefin matrices. They are typically grafted with maleic anhydride or similar functional groups.

What are the key specifications for the PA6/PA66 impact modifiers?

Impact modifiers for PA6 and PA66 are usually specified by melt flow index (MFI 5‑15 g/10 min) and impact energy (Izod or Charpy values above 30 kJ/m²). The supplier’s data sheets should detail these parameters.

Is a safety data sheet (SDS) provided for each product?

Yes, standard practice for chemical exporters from China includes supplying an SDS that meets GHS labeling requirements for each additive.

What packaging formats are available for the listed chemicals?

Typical packaging includes 25 kg bulk bags, 200 kg drums, and 1 ton bulk containers, with moisture‑controlled liners for hygroscopic materials.

Which certifications should a buyer request for these additives?

Buyers should request confirmation of REACH registration for EU shipments, ISO 9001 quality management certification, and any third‑party test reports relevant to melt flow, impact strength, or thermal stability.

What is the usual lead time for orders from this supplier?

Lead times for specialty polymer additives from Chinese manufacturers generally range from 30 to 45 days after order confirmation, subject to production scheduling and raw‑material availability.

Which Incoterms are commonly used for shipping these products?

FOB Shanghai is the most common term, with CIF options also offered depending on the buyer’s preference.

How can a buyer verify product quality before a full order?

Request a representative sample and accompanying certificate of analysis (CoA). Laboratory testing of melt flow index, impact energy, and anhydride content will confirm compliance with the buyer’s specifications.
