Product Description
Product Details
Introduction
1,3-Diphenylguanidine (DPG) is a medium-speed accelerator for rubber. It can be used as an activator for thiazole-type thiuram and sulfenamide-type accelerators. When used in combination with accelerators DM and TMTD in continuous vulcanisation. It possesses anti-ageing properties and is suitable for both natural and synthetic rubbers, though it is not suitable for latex. It is primarily used in the manufacture of rubber industrial products such as tyres, rubber sheets, and rubber shoes.
Application
Diphenylguanidine DPG is used as a co-accelerator in most sulphur-vulcanised elastomers, natural rubber and styrene-butadiene rubber ingredients, together with thiazole and sulfonamide accelerators.
Accelerator DPG is mainly used as a medium-speed accelerator for natural rubber and synthetic rubber. It is often used as an activator for thiazole, thiuram and sulfonamide accelerators. When using thiazole accelerators as the second accelerator, the ageing resistance of the vulcanised rubber is reduced, and an appropriate antioxidant must be added.
Diphenylguanidine DPG is used as a gelling agent in the foaming process of natural rubber and styrene-butadiene rubber latex.
Diphenylguanidine DPG causes discolouration, so it is not suitable for white and light-coloured rubber products.
Diphenylguanidine DPG acts as a plasticizer and shrinkage agent in chloroprene rubber.
