This study examined the effect of recycled carbon-based material (rCBM), obtained by chemical degradation of end-of-life tires, on the mixture of tire tread (rubber composite) by comparing it with commercial carbon black (CB-N550). The new chemical degradation method was defined and the new rCBM was obtained. This newly method is more

US4451610A Preparation of curable solid polyester resin
A method of preparing curable solid polyester resin pellets and powders comprising (a) preparing a liquid mixture consisting essentially of an unsaturated polyester resin, at least one monomeric unsaturated polymerizable material containing a terminal ethylene group, and an alkaline earth metal oxide or hydroxide in an amount effective to provide a desired increase in
DPTT is an effective primary or secondary accelerator or sulfur donor for use in IIR, CSM, EPDM, NR, IR, SBR and CR. DPTT improves heat resistance and aging properties of vulcanizates. It is particularly suitable for light-colored stocks. MBT. Fast, non-staining accelerator for both dry rubber and latex applications.
- What is a rubber accelerator?
- Rubber accelerators are chemical substances that are used to speed up the vulcanization process of rubber, which is crucial for enhancing the material's strength, durability, and elasticity.
- Are accelerators suitable for synthetic rubber?
- For example, accelerators for natural rubber may not be suitable for synthetic rubbers. - **Processing Conditions**: The temperature, pressure, and mixing conditions during the vulcanization process can influence the choice of accelerators.
- Why is mastering rubber accelerators important?
- Mastering rubber accelerators is essential for global chemical buyers to ensure the quality and efficiency of rubber production. By understanding the different types of accelerators, their functions, and the factors influencing their selection, buyers can make informed decisions that optimize their rubber manufacturing processes.
- What are the different types of rubber accelerators?
- There are several types of rubber accelerators, each with unique properties and applications. The most common types include: - **Promoters**: These accelerators enhance the rate of vulcanization by increasing the effectiveness of sulfur. Examples include benzothiazoles and thiurams.
