classification of rubber accelerator zdec
this category of accelerators includes widely used commercial accelerators such as mbt, mbts, and zmbt (nambt, the sodium salt of mbt, is also used in some latex goods manufacturing). thiazoles are primary accelerators with a medium-fast curing rate and moderate processing safety.

on the various roles of 1,3-diphenyl guanidine in silica/silane
more chemically bound rubber does form when dpg is present, so the reaction sites on the silica surface are more shielded by dpg molecules but not blocked for the access of silane. additionally, according to the bound rubber model proposed by choi and ko [ 26 ], silanization should first occur before dpg adsorption in order to form chemically bound rubber.
1,3-diphenylguanidine, benzothiazole, benzotriazole, and their.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). bth and its derivatives (bths) are also used as corrosion inhibitors, herbicides, slimicides, algicides, fungicides, and ultraviolet (uv) light stabilizers ( liao et al., 2018 ).

- 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?
- Is DTG used in rubber products in India and Pakistan?
- A greater proportion of DTG implies that this compound is also an additive used in rubber products in India and Pakistan. In dust samples collected from the United States, the distribution profiles of DPG, DTG, and TPG corresponded to their consumption volume (Table 1). Figure 2.
- Which additives are found in rubberized playground soils?
- Elevated levels of rubber additives were found in rubberized playground soils. 1,3-Diphenylguanidine (DPG), benzothiazole (BTH), benzotriazole (BTR), and their derivatives are high-production-volume chemicals widely used in tires, corrosion inhibitors and plastic products.
- Why is DPG used in silica-reinforced rubber compounds?
- Further, while reacting with the silanol groups DPG reduces the polarity of silica by being adsorbed onto the silica surface [, , ]; and finally, DPG is also capable of accelerating the silanization reaction [2,4,7,8]. DPG therefore has turned into a multi-purpose compounding ingredient in silica-reinforced rubber compounds.
- What is accelerator DPG?
- Accelerator DPG is useful as an accelerator/activator for natural rubber, SBR and NBR. It activates accelerators such as MBT, MBTS and sulfenamides. It is a strong secondary for CBTS, BBTS, OBTS, MBT and MBTS. DPG requires the use of zinc oxide and fatty acids. DPG provides satisfactory processing safety and storage stability to rubber compounds.
- What are the characteristics of DPG rubber?
- 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.
