| Note: 1. Vulcanization conditions: 170 ℃,5min, double 25 vulcanizing agent, adding 1.2%, platinum vulcanizing agent can also be used. Molding to make test pieces; 2. Different vulcanizing agents and different testing and production conditions will result in different data. 3, the above listed physical data for reference only, if you need the inspection report of the goods, please ask the sales office. | ||||
5. Usage and operation
1. Open the mill for about 3-5 minutes to make the rubber roll and mix evenly.
2. Add the color paste to make it uniform (if necessary), add the vulcanizing agent, and hit ten to fifteen rolls to make the vulcanizing agent evenly dispersed in the glue, and the glue surface becomes smooth.
3. After the rubber material is rolled, it will be formed into a sheet. The two pieces are separated by adhesive tape.
4. The production vulcanization temperature is 170 ℃-350 ℃, and the specific setting is determined according to the equipment, extrusion speed and cable specifications.
6. Safety and storage
* Store at room temperature for six months from the date of production.
* Store in a dry and cool place, avoid direct sunlight.
* Before use, please read the product's instructions and product safety data sheet carefully.
7. Packing
* 20KG carton, lined with plastic bags.
