There are various types of industrial rubber sheets, and the rubber material used to produce any type of rubber sheet is a multi-component system material formed by combining the main material with various additives, where each component plays a certain role. For example, the vulcanization system (including crosslinking agents (vulcanizing agents), co crosslinking agents (vulcanizing agents and additives), accelerators, and activators) can chemically crosslink linear rubber macromolecules to form a three-dimensional spatial network structure, thereby transforming plastic viscoelastic rubber materials into highly elastic vulcanized rubber; Reinforcing fillers can ensure that the rubber material has the required mechanical properties, improve processing performance, and reduce costs; Softening plasticizers and other processing aids can endow the rubber material with necessary processability, improve cold resistance, and also reduce costs; Antioxidants can improve the aging resistance of vulcanized rubber and provide protection against various types of aging, thereby extending the service life of rubber sheets.

Raw rubber is the basic material for manufacturing rubber sheets, which generally does not contain any additives, but sometimes may also contain certain additives. At present, there are no less than 100 types of rubber (including plastic modified elastomers). If estimated by brand, there are actually over 1000 types, and their classification is roughly as follows. According to the source and method of production, it can be divided into two categories: natural rubber and synthetic rubber. The consumption of natural rubber accounts for about 42%, while the consumption of synthetic rubber accounts for about 58%. According to the first classification method based on application scope and purpose, rubber can be divided into two categories: general-purpose rubber (NR, BR, SBR, NBR, EPR, CR, IIR) and specialty rubber (FPM, Q, PUR, AEM, ACM, CO, T, CM, CSM, etc.).

According to the type and cross-linking form of rubber, industrial rubber sheets are divided into the following categories: one category is based on heat and oil resistance functions: ordinary rubber sheets, heat-resistant rubber sheets, oil resistant rubber sheets, heat-resistant and oil resistant rubber sheets, weather aging resistant rubber sheets, and special chemical medium resistant rubber sheets. The other is divided into general rubber plate, hard rubber plate, semi hard rubber plate, hard rubber plate, microporous rubber plate, sponge rubber, foam rubber plate, etc.

Hard rubber products:

Rubber with a glass transition temperature above room temperature and almost unable to stretch is called hard rubber. It is made by adding a large amount of sulfur to NR or SR and sulfurizing for a long time. The products made from it are called hard rubber products. Hard rubber is a black hard substance at room temperature, with good chemical stability, excellent resistance to chemical corrosion and organic solvents, low water absorption, high tensile strength, and excellent electrical insulation properties. It can be machined. Its disadvantage is that it is brittle and prone to aging under ultraviolet radiation. Commonly used in the production of electrical insulation products, chemical equipment linings, and transition layers for rubber and metal bonding.
