Materials Special Issue : Recent Advances in Rubber
This could be improved to 6.5 MPa by using 2.8 phr of 1,3-DiPhenylGuanidine (DPG) in the revulcanization formulation. After addition of a silanization step during revulcanization by adding 3.2 phr bis[3-(TriEthoxySilyl)Propyl] Tetrasulfide (TESPT), a silane, to the formulation, the tensile strength of the revulcanizate was further improved to 8

- What is DPG (diphenyl guanidine)?
- DPG (Diphenyl Guanidine) is a widely used rubber accelerator that plays a vital role in the production of rubber products. This article aims to provide an overview of DPG, its characteristics, its applications in rubber product manufacturing, potential product combinations, and important considerations for commercial procurement. 1. What is DPG?
- What are the characteristics of DPG rubber?
- 2. Characteristics of DPG: - Acceleration: DPG functions as a medium-fast primary accelerator, meaning it promotes the vulcanization process in rubber production. - Moderate reactivity: It offers a balanced level of reactivity, making it suitable for a wide range of rubber types, including natural rubber (NR), synthetic rubber, and blends.
- What is DPG used for?
- DPG finds extensive use in the production of various rubber products, including: - Tires: It is commonly used in tire manufacturing to accelerate vulcanization, ensuring optimal performance, durability, and tread wear resistance.
- Is 1,3-diphenylguanidine a vulcanization accelerator?
- As a widely used secondary vulcanization accelerator in the rubber industry, 1,3-diphenylguanidine (DPG) poses risks to human health and the environment. To compare and comprehend the disinfection process of DPG, this work investigates the reaction kinetics, toxicity, and transformation products (TP …
- What is DPG & BTH used for?
- 1,3-Diphenylguanidine (DPG), benzothiazole (BTH), benzotriazole (BTR), and their derivatives are used in a wide range of industrial processes. DPG and BTH are typically used in the vulcanization of rubber and other polymers, including tires, plastics, and leather products (ECHA, 2020; ECHA, 2021; Li and Kannan, 2023b; Zhao et al., 2023).
- What are the advantages of DPG?
- Moderate reactivity: It offers a balanced level of reactivity, making it suitable for a wide range of rubber types, including natural rubber (NR), synthetic rubber, and blends. - Good scorch safety: DPG provides good scorch safety, preventing premature curing during processing and allowing for extended processing time.
