About Puyang Tennants Chemical Co., Ltd. - Resin Supplier in China

China, with an active catalogue of six resin products, supplies a range of hydrocarbon resins manufactured by Puyang Tennants Chemical Co., Ltd. The listed items include C5 hydrocarbon resin, a C5 formulation for adhesives, a resin formulated for tire rubber compounds, a C5/C9 copolymerized resin, a C9 hydrocarbon resin, and coumarone resin. All products fall under the broader resin category, which is classified in international trade under synthetic resin headings. The supplier’s catalogue does not disclose additional product families beyond these six entries.

The six entries cover both pure C5 and C9 based resins as well as blended or copolymerized grades. Each product is identified by its feedstock composition rather than a separate chemical name, reflecting the common practice of labeling hydrocarbon resins by the dominant monomer fraction. The list also highlights a specialty coumarone resin, a phenolic‑type material derived from coumarone‑based feedstock, which is often used in high‑temperature applications. No further details such as molecular weight or acid number are provided in the catalogue.

Product Range and Specialties of Puyang Tennants Chemical Co., Ltd.

The catalogue focuses exclusively on hydrocarbon resins derived from C5 and C9 petroleum fractions and a coumarone‑based resin. In the industry, C5 resins are typically supplied with a softening point between 70 °C and 120 °C, an acid value below 20 mg KOH g‑1, and a melt flow index (MFI) ranging from 5 to 30 g/10 min (ASTM D1238). C9 resins usually exhibit a higher softening point (110 °C - 150 °C) and a lower acid value, making them suitable for high‑temperature adhesives and rubber compounds. Copolymerized C5/C9 resins combine the tackiness of C5 with the thermal stability of C9, and are often specified by a target softening point and a defined percentage of C9 content.

Coumarone resin, sometimes classified as a phenolic resin, is evaluated by its phenol‑formaldehyde equivalent weight, gel time, and heat resistance (often above 180 °C). Buyers commonly request data sheets that list these parameters together with compliance to ASTM D3528 (phenolic resins) or ISO 1628. The product range therefore aligns with standard industry specifications for synthetic hydrocarbon resins used in adhesives, coatings, and rubber compounding.

Trade and Export Information - Puyang Tennants Chemical Co., Ltd.

China is a major exporter of hydrocarbon resins, supplying large volumes to Southeast Asian tire manufacturers, European adhesive producers, and North American rubber compounding firms. Export shipments are typically loaded in 20‑ft or 40‑ft containers, with resin granules or powders packed in moisture‑proof laminated bags of 25 kg or 500 kg, depending on buyer preference. While the catalogue does not list HS codes, hydrocarbon resins are generally classified under Chapter 39 of the Harmonized System, and importers often need to provide a material safety data sheet (SDS) and comply with REACH registration when shipping to the EU.

Typical buyer requirements include proof of compliance with ISO 9001 quality management, REACH registration numbers for the specific resin grade, and, where applicable, certification to ASTM D1238 for melt flow testing. Chinese exporters of these resins also follow customs inspection procedures that verify packaging integrity, accurate HS declaration, and the presence of a certificate of origin for preferential tariff treatment under various trade agreements.

Sourcing from Puyang Tennants Chemical Co., Ltd. - Buyer Guidance

When sourcing hydrocarbon resins from this supplier, request a detailed technical data sheet that lists softening point, acid value, MFI, and any residual monomer content. Ask for an independent laboratory test report that follows ASTM D1238 (MFI) and ASTM D1305 (softening point) to verify the quoted specifications. Verify that the supplier can provide a current SDS, REACH registration confirmation, and, if required by the destination market, a certificate of analysis for each batch shipped.

Typical minimum order quantities for bulk hydrocarbon resins range from 15 metric tons to 30 metric tons, with lead times of four to six weeks after order confirmation. Clarify packaging options - whether bulk bags, 25 kg poly‑bags, or drum shipments - and confirm that the packaging meets the buyer’s moisture‑sensitivity requirements. Ensure that the supplier can arrange Incoterms such as FOB Shanghai or CIF Rotterdam, and that freight forwarders are experienced in handling hazardous‑material declarations for resin powders.

What types of hydrocarbon resin does Puyang Tennants Chemical offer?

The supplier lists six items: C5 hydrocarbon resin, C5 resin formulated for adhesives, hydrocarbon resin for tire rubbers, a C5/C9 copolymerized resin, C9 hydrocarbon resin, and coumarone resin.

Are technical data sheets available for each resin grade?

Buyers should request a technical data sheet that includes softening point, acid value, melt flow index, and any applicable ASTM or ISO test references before placing an order.

What certifications should a buyer verify for these resins?

Typical certifications include ISO 9001 for quality management, REACH registration for EU compliance, and any relevant ASTM test reports such as D1238 for melt flow.

What packaging formats are commonly used for these hydrocarbon resins?

Resins are usually packed in moisture‑proof laminated bags of 25 kg or bulk bags of 500 kg, and can also be shipped in 20‑ft or 40‑ft containers depending on order size.

What is a typical minimum order quantity and lead time?

Minimum order quantities generally start at 15 metric tons, with a production and preparation lead time of four to six weeks after order confirmation.

Which Incoterms are commonly applied for shipments from China?

Suppliers commonly use FOB Shanghai for buyer‑arranged freight or CIF major European ports such as Rotterdam, allowing the buyer to choose the preferred logistics arrangement.

How can a buyer obtain a sample before a full order?

A small sample, typically 5 kg, can be requested for laboratory evaluation; the supplier should provide the sample together with an SDS and a preliminary test report.

What regulatory documents are required for export to the EU?

Export to the EU usually requires a REACH registration number, a certificate of origin, and an SDS that meets EU safety standards, in addition to any customs declaration under HS Chapter 39.
