YLSCH-RBB®accelerator DPG-80 is diphenylguanidine (DPG) in the form of pre-dispersed masterbatch particles. It is a commonly used vulcanization accelerator in the rubber industry. This product works by pre-dispersing diphenylguanidine in a carrier material, usually EPDM (ethylene-propylene-diene monomer rubber) or other synthetic rubber, to improve its ease of use and efficiency. The following is a detailed introduction to the accelerator DPG-80:

Basic information about YLSCH-RBB®accelerator DPG-80

1. Chemical composition:

• Main ingredients: diphenylguanidine (DPG)
• Chemical formula: C13H13N3
• Content: usually 80%, the rest is carrier material (such as EPDM)

2. Physical properties:

• Form: Granule
• Color: light yellow to light gray
• Density: about 1.1-1.2 g/cm³

Main functions and functions

1. Vulcanization accelerator:

• Accelerate the vulcanization speed: DPG-80 can significantly accelerate the vulcanization reaction speed of rubber, allowing the rubber to reach the expected degree of vulcanization in a shorter period of time.
• Improve vulcanization efficiency: By promoting the vulcanization reaction, DPG-80 can improve vulcanization efficiency, reduce production cycle, and improve production efficiency.

2. Activator:

• Synergy with other accelerators: DPG-80 is often used in conjunction with thiazole accelerators (such as MBT, MBTS), which can enhance the activity of these accelerators and improve the overall vulcanization effect.
• Improved vulcanization system: In the vulcanization system, DPG-80 can increase the vulcanization cross-linking density, thereby improving the physical and mechanical properties of rubber, such as strength, hardness and wear resistance.

Advantage

1. Easy to disperse:

• Because it is in the form of pre-dispersed masterbatch particles, DPG-80 is easy to disperse evenly during the mixing process, reducing agglomeration and improving the processing performance of the rubber.

2. Reduce dust:

• The pre-dispersed form reduces the generation of dust, reduces the health risks of operating workers, and improves the cleanliness of the workshop environment.

3. Accurate measurement:

• The form of pre-dispersed masterbatch particles makes the measurement more accurate and reduces product performance fluctuations caused by weighing errors.

4. Storage stability:

• The pre-dispersed form improves storage stability and reduces moisture absorption and caking.

Application areas

1. Tires:

• Used in tire production, especially in the production of radial tires and bias tires, to improve vulcanization speed and rubber properties.

2. Industrial rubber products:

• It is widely used in the production of various industrial rubber products, such as conveyor belts, seals, shock absorbers, etc.

3. Shoe materials:

• Used in the production of rubber parts such as soles and heels to improve wear resistance and elasticity.

Instructions

1. Add method:

• DPG-80 can be added directly to the rubber mixture during the mixing process, usually in the early stages of mixing to ensure it is fully dispersed.

2. Dosage:

• The specific dosage depends on the formula and process requirements, usually between 1-3 parts (relative to 100 parts of rubber).

Environmental protection and safety

1. Environmental advantages:

• The pre-dispersed form reduces dust and volatile organic compound (VOC) emissions and is more environmentally friendly.

2. Safety measures:

• Dust exposure during operations is reduced, reducing worker health risks and improving the safety of the workshop environment.

Summarize

The accelerator DPG-80, as an efficient, environmentally friendly and safe form of pre-dispersed masterbatch, has important application value in the rubber industry. By improving the vulcanization reaction and improving processing performance, DPG-80 not only improves the quality and performance of rubber products, but also significantly improves the environmental protection and safety of the production process. Widely used in tires, industrial rubber products and shoe materials, DPG-80 will continue to play an important role in the rubber industry.
