CPE/CR Rubber Vulcanizer H631
The product is a light‑yellow powder known as CPE/CR Rubber Vulcanizer H631. It acts as a thiadiazole‑based cross‑linking agent for chlorinated polyethylene (CPE) and chloroprene (CR) rubbers. The supplier states it can be applied in moulding, continuous, pot‑type and microwave vulcanisation processes. It is marketed as a high‑efficiency agent that imparts heat resistance, ozone ageing resistance and flame retardancy.
H631 enables low‑pressure, die‑less vulcanisation, avoiding the higher temperatures and pressures required by conventional peroxide systems. It can replace expensive plasticisers such as DOP with cheaper aromatic oils while maintaining processing safety and longer scorch time. The agent is also effective as a co‑vulcaniser for blends such as CPE/EPDM, CPE/NR and CPE/CR. Typical industry practice grades this class of vulcaniser to a particle size below 200 µm and a bulk density around 0.8 g cm‑3.
Common applications include rubber components for cables, hoses and tapes where durability and flame resistance are required. Importers in automotive, electrical and construction sectors often source H631 for formulation of specialised rubber compounds. Trade terms, minimum order quantities and Incoterms are not disclosed in the listing and should be confirmed directly with Yantai Heng Nuo Chemical Technology Co., Ltd.

Sourcing CPE/CR Rubber Vulcanizer H631 from Yantai Heng Nuo Chemical Technology Co., Ltd - China Import Guide
Before placing an order for H631, importers should verify the supplier’s business registration, confirm the existence of a valid tax or export licence, and request a recent factory audit report. Checking the authenticity of the product’s safety data sheet and any third‑party test certificates will help ensure the vulcaniser matches the described performance. It is also wise to ask for a sample batch for preliminary trials.
Clarify the expected lead time, preferred Incoterms and the shipping port in China with Yantai Heng Nuo Chemical Technology Co., Ltd. Typical arrangements involve FOB Yantai or CIF Shanghai, but the supplier has not disclosed its standard terms. Request a detailed pro‑forma invoice that outlines freight charges, insurance and any handling fees. Payment methods such as T/T in advance or LC at sight should be confirmed before contract signing.
Arrange an independent third‑party inspection at the factory or at the loading port to verify batch consistency and compliance with the stated properties. Request certificates of analysis, the latest safety data sheet and any test reports for heat resistance, ozone ageing and flame retardancy. Maintaining proper documentation will smooth customs clearance and reduce the risk of receiving non‑conforming material.
