Different vulcanizing agents, different testing conditions, data will be different; 3. The above physical property data are for reference only. If you need the inspection report of the goods, please ask the sales office for it. | |||||
Usage and operation
1. Open the mill for about 3-5 minutes to make the rubber roll and mix evenly.
2.Then add the color paste to make it even (if necessary), and then add the curing agent. Roll 10 to 15 rolls to make the curing agent evenly dispersed in the rubber, and the rubber surface becomes smooth.
3.After the rubber is rolled down, it forms a sheet. Each piece is separated by a membrane.
