Buy & Import 40% Zinc Rubber Sulfide Active Agent from Qingdao Topsen chemical - China Wholesale Supply

40% Zinc Rubber Sulfide Active Agent is a nano zinc oxide masterbatch designed as a low-zinc activator for rubber vulcanisation. The product, branded as Topfine® CR510, contains half the zinc content of conventional zinc oxide while maintaining high vulcanisation activity and excellent dispersion in rubber compounds. It addresses regulatory restrictions such as the EU 2017/1413 ban on medicinal zinc oxide in piglet feed and California’s SB 1260 limits on zinc in motor vehicle tires, offering an environmentally compliant alternative for rubber manufacturers.

The active agent uses nano-scale zinc oxide particles to achieve uniform distribution within rubber matrices, reducing the overall zinc load without sacrificing performance. Typical applications include tires, industrial belts, and hoses where zinc oxide acts as a vulcanising agent. Standard rubber formulations often require 3-5 phr (parts per hundred rubber) of zinc oxide, but Topfine® CR510 achieves comparable results at lower dosages, improving cost efficiency and sustainability.

Buyers in the automotive and industrial rubber sectors use this agent to meet environmental standards while preserving mechanical properties like tensile strength and abrasion resistance. The product is supplied as a masterbatch for easy incorporation into existing production lines. Confirm minimum order quantities, packaging formats, and lead times directly with Qingdao Topsen chemical, as these are not specified in the listing. The material is compatible with natural and synthetic rubbers, including SBR, NR, and EPDM.

Frequently Asked Questions About 40% Zinc Rubber Sulfide Active Agent from Qingdao Topsen chemical
Topfine® CR510 contains 40% zinc, which is approximately half the zinc content of conventional zinc oxide (ZnO) used in rubber formulations. This reduction is achieved through nano-scale dispersion, maintaining vulcanisation activity while lowering the overall zinc load.

Sourcing 40% Zinc Rubber Sulfide Active Agent from Qingdao Topsen chemical - China Import Guide

Before ordering, verify the product’s compliance with your target market’s environmental and safety regulations, such as REACH in the EU or EPA standards in the US. Request a Certificate of Analysis (CoA) for zinc content and particle size distribution to ensure consistency with your rubber formulation requirements. Confirm whether the masterbatch is pre-dispersed in a specific elastomer or provided as a pure additive.

Logistics details to confirm include Incoterms (e.g., FOB Qingdao), lead time for bulk orders, and shipping documentation such as MSDS and export permits. Qingdao’s port infrastructure supports containerized shipments, but check if the supplier offers break-bulk options for smaller quantities. Payment terms, such as TT (Telegraphic Transfer) or LC (Letter of Credit), should also be clarified upfront.

For quality control, conduct incoming inspection for zinc content (via ICP-OES or XRF) and particle size (using SEM or laser diffraction). Perform a trial batch in your production line to validate dispersion and vulcanisation performance. Request a sample for testing if the supplier offers this option, and ensure all documentation, including CoA and compliance certificates, is provided before full-scale ordering.
