Needs in according to the basic formula design, the use of performance and process conditions, through the test, optimization and evaluation, reasonably choosing raw materials, to determine the relationship between dosage, the ratio of of all kinds of materials, and according to different purposes, there will be the use of different types of.

Rubber formula:
1, custom silicone products manufacturer to introduce basic recipe is also called the standard recipe, commonly used in raw rubber and compound identification. At the beginning time when using a raw rubber and compound, using basic formula test its basic processing performance and physical performance. Basic formula design principle is to use the traditional coordination with the quantity, so that were compared with the previous similar material. Formula should be simplified as much as possible, including only can reflect the basic process of the performance and basic physical properties of vulcanizates of basic components, consisting of the basic components of rubber, can reflect the basic process of the performance (e.g., Mooney viscosity, Mooney scorch, etc.), but also reflects the basic physical properties of vulcanized rubber.

2, in order to make rubber products meet certain performance requirements for the formula design, its purpose is to meet the performance requirements for product and process requirements, certain features increases, etc. Formula should be on the basis of the basic formula, performance fully consider the collocation of all kinds of performance, to meet the demand of the products using conditions shall prevail. Usually formula design personnel in the laboratory for product research and development of experimental formula is performance formula, performance formula is a formula formula designers use the most.

3, custom silicone products manufacturer is introduced due to the performance formula developed under laboratory conditions, tend to appear in the production of some technological problems, such as mixing dispersion chelating agent is bad, the rubber scorch yue inches shorter, big mouth expansion when it is squeezed, calendering sticky roller, etc. Therefore, from the performance of the laboratory developed unitary board, must go through the scene production equipment and production process conditions of the inspection, this is called expansion test, no problem only by expanding test of rubber formula, can be formally put into production.
