Product Details
Product Description
As a professional factory and reliable manufacturer for the global chemical industry, Chemost supplies premium ZDTP to B2B buyers, rubber processing plants, and additive blending facilities worldwide.
Zinc dithiophosphate (ZDTP) is a highly versatile chemical compound that serves a dual purpose in modern industrial manufacturing. It is widely recognized both as a high-performance anti-wear component for lubricants and as a highly effective rubber accelerator.
In the elastomer industry, it functions as an outstanding specialty accelerator for the rapid vulcanization of EPDM and natural rubbers. Because it does not produce harmful nitrosamines during the curing process, it is the ideal environmental replacement for traditional accelerators. Our factory ensures that every batch maintains strict purity and consistency, guaranteeing optimal dispersion and curing kinetics for your production lines.

Product Features
- Environmental Compliance: It does not generate carcinogenic nitrosamines during the curing process, making it a safer and compliant alternative to standard thiurams and dithiocarbamates.
- Excellent Scorch Safety: Provides a long delayed action, preventing premature cross-linking during the high-temperature mixing and extrusion phases.
- Rapid Vulcanization Rate: Once the curing temperature is reached, it drives a fast cross-linking reaction, significantly increasing factory throughput and productivity.
- High Reversion Resistance: Forms stable cross-links that prevent the rubber matrix from reverting, ensuring the final molded products maintain their physical integrity over time.
- Strong Synergy: Exhibits powerful synergistic effects when combined with thiazoles or sulfenamides, optimizing the overall curing system.
Product Synonyms and Masterbatch Specifications
Within the international supply chain, procurement engineers and formulators refer to this chemical under various designations. As a direct factory, Chemost produces and supplies all the following specifications.
Zinc dithiophosphate
Zinc dithiophosphate represents the pure chemical structure. It serves as the active foundation for both advanced anti-wear lubrication components and high-efficiency vulcanization systems.
Zdtp additive & Zdtp accelerator
When utilized in the petroleum sector, it functions as a highly effective zdtp additive to protect metal surfaces. In the polymer sector, it acts as a premium zdtp accelerator to cross-link synthetic rubber compounds securely and safely.
Zdtp 70 & Zdtp 50
To solve dust flying issues and improve dispersion in the internal mixer, we supply pre-dispersed polymer-bound masterbatches. Zdtp 70 contains 70% active ingredient on a polymer binder, while zdtp 50 contains a 50% concentration. These forms greatly enhance factory environment cleanliness and weighing accuracy.
Accelerators in rubber
The strategic use of accelerators in rubber determines the final physical properties of the tire or industrial hose. This specific chemical acts as an exceptional secondary or primary agent, particularly excelling in EPDM profiles and molded parts.
Frequently Asked Questions FAQ
Q:What is the rubber accelerator ZDTP?
A:It is a specialized chemical agent (Zinc dithiophosphate) added to elastomer formulations to speed up the sulfur vulcanization process. It is uniquely valued because it does not release carcinogenic nitrosamines, making it a safe choice for manufacturing EPDM weather strips, hoses, and general molded goods.
Q:What is a rubber accelerator?
A:A rubber accelerator is a chemical additive used in the rubber compounding industry. Its primary function is to increase the speed of the vulcanization (curing) reaction, allowing the rubber to transition from a soft, sticky state into a durable, elastic material quickly and efficiently at lower temperatures.
