2.Product Description
2.1Properties:
The materials are of natural color/white color and particle shape, with the basic material of rubber (e.g. EPDM). The hyperoxides are cross-linked mixture of the main vulcanizing system. They can be used in CV (continuous vulcanizing) extrusion product line. The properties are in line with the national standards such as TICW-2009
etc.

2.2 Machining Process
2.2.1 Drying treatment should be carried out before the production use.
2.2.2 The CV (continuous vulcanizing) extrusion product line Can be used for production. It is recommended to use screw rods with length-to-diameter ratios between 15:1 and 24:1.
2.2.3 Before extrusion, clean screw rods to make sure product cleanness. It is suggested to add filter screens with sieve number of 20/40 or 20/60 in front of the die to avoid impurity entering during the extrusion process, and to keep flux pressure in order to obtain good appearance and material compaction.
