  The principles of rubber formulation design can be summarized as follows:

  1. Ensure that the vulcanizate has the specified technical performance and make the product of high quality;

  2. Good processing technology performance in rubber and product manufacturing process, so that the product reaches high yield;

  3. Low cost and cheap price;

  4. The raw rubber, polymers and various raw materials used are easily available;

  5. High labor productivity and low energy consumption during processing and manufacturing;

  6. Meet environmental protection and health requirements;

  It is impossible for any one rubber formula to achieve all-optimal performance in all performance indicators. In many cases, the formulation design should follow

  Design Principles:

  ① Reduce the cost of rubber without reducing quality;

  ② Improve product quality without increasing rubber cost. To make the performance, cost and processing technology of rubber products

  To achieve the best comprehensive balance of three aspects. With the least material consumption, the shortest time and the minimum workload, through scientific formula

  Design method, grasp the inherent law of raw material coordination, and design practical formula.

  Classification of rubber formula:

  1. Basic formula (also known as standard formula)

  2. Performance formula (technical formula)

  3. Practical formula (production formula)

  A complete rubber formula should include the following components: 1. The main material (such as natural rubber, synthetic rubber, rubber and resin blending, etc.) 2. Vulcanization system (vulcanizing agent, vulcanization accelerator, active agent, etc.) 3. Protection system (Various anti-aging agents, stabilizers) 4. Reinforcing and filling systems 5. Plasticizing systems (such as various softeners, plasticizers, operating aids, etc.) 6. Special performance systems (such as anti-scorching agents, plastification Agents, dispersants, solubilizers, hardeners, modifiers, foaming agents, colorants, deodorants, release agents, tackifiers, defoamers, release agents, extenders, etc. In addition to the table of raw material usage and ratio, it also contains more detailed content. Such as the name and code of the rubber compound, the purpose of the rubber compound, the rubber content, the density of the rubber compound, the volume cost or the quality cost, the technical properties of the rubber compound, and the physical properties of the vulcanizate.
