| Note: 1. Curing condition: curing at 170 degrees Celsius for 5 minutes, the proportion of the DHBP was 1.2%; platinum vulcanizing agent can also be used, and by compression molding to make the test sheet. 2. 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.
Safety and Storage
* The normal temperature shelf life of silica gel is six months. It is recommended to use it within three months. If it is beyond three months, the mixing time of the product will be extended.
*Store in a dry and cool place, away from direct sunlight.
* Place out of reach of children.
Packing
* Packed in 20kg cartons lined with plastic bags. Please store in a cool place.
