Black rubber sheet is a sheet-like product with a certain thickness and area, mainly made of rubber and processed through specific techniques. It is widely used in various fields such as industry, transportation, and construction. So, what material is black rubber sheet made of?

The main material of black rubber sheet is rubber.

Rubber is a highly elastic polymer material with good elasticity, wear resistance, corrosion resistance, and insulation properties. Depending on specific usage requirements, other components and additives such as fillers, vulcanizing agents, anti-aging agents, reinforcing agents, and accelerators may be added to the rubber sheet. These additives can improve the performance of the rubber sheet, making it more suitable for specific application scenarios.

Specifically, the production process of rubber sheets includes the following key steps:

1. Mixing

During the mixing process, various compounding agents such as carbon black, vulcanizing agents, and anti-aging agents are uniformly mixed into the rubber. This step ensures the performance indicators of the rubber sheet, such as hardness and wear resistance.

2. Calendering or Extrusion

The mixed rubber compound is then calendered or extruded to form a blank of a certain shape. This step can be accomplished using a calender or an extruder. Through this process, the rubber sheet begins to take on its basic form.

3. Vulcanization

The semi-finished product needs to undergo vulcanization to become a highly elastic final product. The vulcanization process is usually carried out using a flat vulcanizer or a drum vulcanizer. Vulcanization causes the rubber molecules to form a three-dimensional network structure, greatly enhancing its elasticity and durability.

Black rubber sheets have high physical and mechanical properties and can operate in environments with low pressure and a temperature range of 20°C to 140°C. This type of sheet is widely used in industrial enterprises, transportation departments, and building floors, often for making sealing gaskets, rubber pads, door and window seals, and laying workbenches and floors.

According to their uses, rubber sheets can be divided into industrial rubber sheets and rubber flooring.

Industrial rubber sheets are mainly used for sealing and buffering in industrial equipment, while rubber flooring is widely used for laying building interior floors due to its wear resistance and corrosion resistance.
