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.
effect of 1,3-diphenyl-guanidine (dpg) mixing step.- semantic scholar,1,3-diphenylguanidine (dpg) is commonly used as a secondary accelerator which not only acts as booster of cure but also activating silanization reaction. the aim of this study is to increase the interaction between silica and rubber by using dpg. in this study, mixing was proceeded in two steps. the t-1 compound is mixed dpg with silica and silane coupling agent in the kneader at high.
- 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 is DPG in chemistry?
- DPG is an organic compound belonging to the guanidine class of accelerators. It is a white to pale yellow powder with a faint odor. Chemically, it consists of diphenyl guanidine molecules. DPG is known for its solubility in rubber and compatibility with various types of rubber. 2. Characteristics of DPG:
- 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.
- What is DPG & sulfur used for?
- DPG and sulfur: This combination is widely used in tire manufacturing and other rubber applications, providing excellent vulcanization properties, aging resistance, and overall performance.
- What is DPG used for?
- DPG requires the use of zinc oxide and fatty acids. DPG provides satisfactory processing safety and storage stability to rubber compounds. In light colored goods, it causes a brown discoloration and is not recommended for use in compounds that have contact with food (imparts bitter taste). For best aging results, an antioxidant is required.
- Is DPG poisonous?
- DPG is grayish-white powder/granule. No taste, no poison. Density is 1.08-1.19.Soluble in acetone ethyl acetate, benzene, alcohol, slightly soluble in CCI4; Insoluble in water and gasoline. Used as a secondary accelerator with thiazoles and sulphenamides in NR and SBR compounds.
