The effect of vulcanization on the structure and properties of rubber
The effect of vulcanization on structure and properties: In the production process of rubber products, vulcanization is the last processing step. In this process, the rubber undergoes a series of complex chemical reactions, changing from a linear structure to a body-shaped structure, losing...Read more -
How to maintain the flat vulcanizer
Preparations 1. Check the amount of hydraulic oil before use. The height of hydraulic oil is 2/3 of the height of the lower machine base. When the amount of oil is insufficient, it should be added in time. The oil must be finely filtered before injection. Add pure 20# hydraulic oil into the oil f...Read more -

What are the characteristics of EPDM rubber?
1. Low density and high filling Ethylene-propylene rubber is a rubber with a lower density, with a density of 0.87. In addition, it can be filled with a large amount of oil and EPDM. Adding fillers can reduce the cost of rubber products and make up for the high price of ethylene propylene rubber ...Read more -
The difference between natural rubber and compound rubber
Natural rubber is a natural polymer compound with polyisoprene as the main component. Its molecular formula is (C5H8)n. 91% to 94% of its components are rubber hydrocarbons (polyisoprene), and the rest are protein, Non-rubber substances such as fatty acids, ash, sugars, etc. Natural rubber is the...Read more -
The composition of rubber and the characteristics and applications of rubber products
Rubber products are based on raw rubber and added with appropriate amount of compounding agents. … 1. Natural or synthetic rubber without compounding agents or without vulcanization is collectively referred to as raw rubber. Natural rubber has good comprehensive properties, but its output c...Read more -
Comparison of EPDM rubber and silicone rubber materials
Both EPDM rubber and silicone rubber can be used for cold shrink tubing and heat shrink tubing. What is the difference between these two materials? 1. In terms of price: EPDM rubber materials are cheaper than silicone rubber materials. 2. In terms of processing: Silicone rubber is better than EPD...Read more -
What should we do if there are bubbles after rubber vulcanization?
After the glue is vulcanized, there are always some bubbles on the surface of the sample, with different sizes. After cutting, there are also a few bubbles in the middle of the sample. Analysis of the causes of bubbles on the surface of rubber products 1. Uneven rubber mixing and irregular operat...Read more -
The role of stearic acid and zinc oxide in rubber formulations
To a certain extent, zinc stearate can partially replace stearic acid and zinc oxide, but stearic acid and zinc oxide in rubber cannot completely react and have their own effects. Zinc oxide and stearic acid form an activation system in the sulfur vulcanization system, and its main functions are...Read more -
Reasons and protection methods of static electricity during rubber mixing
Static electricity is very common when mixing rubber, no matter the season. When the static electricity is serious, it will cause a fire and cause a production accident. Analysis of the causes of static electricity: There is strong friction between the rubber material and the roller, resulting in...Read more -
