Speaking of rubber extruders, I believe everyone is not unfamiliar. To be honest, rubber extruders are a basic equipment of the rubber industry and one of the key equipments that affect product quality. Important role.
The development of foreign rubber extruders has experienced plunger-type extruder, screw-type hot-feed extruder, ordinary cold-feed extruder, main and auxiliary thread cold-feed extruder, cold-feed exhaust extrusion Machine, pin cold feed extruder, compound extruder and other stages. The rubber extruder is a rubber machine used to extrude treads, inner tubes, hoses and various rubber profiles. It is also used to cover cable and wire products. Common is the screw extruder. When it is working, the rubber compound is stirred, mixed, plasticized and compacted in the barrel by the rotation of the extrusion screw, then moved toward the head, and finally extruded from the mouth. Shaped products. For mechanical products, we have to use them in accordance... less

Ordinary film labels are generally PE, BOPP film stickers (with glue on the back), which can be flexo, embossed, screen printed, offset printed. The surface is protected by waterproof varnish; it can be pasted with a labeling machine,in mould labels: The material and printing are the same as above, but there is no glue. It is placed on the mold wall when the bottle is blown. After the bottle is blown, the label is directly embedded into the surface of the bottle and integrated. At present, the special technology and processing of such labels include foaming inks, which can touch the three-dimensional effect of the text, cold or hot stamping, and the hot stamping part has a metallic texture. That's it. less

It plays a very important role in the field of silicone products and LED lights. It is mainly composed of power motor, speed reducer, speed controller, feed port, extrusion screw, extruder head, etc. It is widely used in silicone tube strips, silicone seal ring sealing strips, LED sleeves, flexible light strips and so on.
2. The rubber extruder is a basic equipment of the rubber industry and one of the key equipments that affect product quality. It plays a very important role in the production of tires and rubber products. Widely used in car tires, car water strips, rubber seal ring strips, door and window wind strips and so on.
In the daily production, the main function of the rubber extruder head is to guide the extruded rubber to the mouth. At the same time, the diversion is removed from the irregular and unstable flowing rubber material of the screw groove of the extruder, and the... less

EPDM rubber is a terpolymer produced by epdm extruders using ethylene, propylene and non-conjugated diene as raw materials. Commercial production began in 1963. Annual consumption worldwide is 800,000 tons. The main feature of EPDM is its superior resistance to oxidation, ozone and erosion. Since EPDM rubber belongs to the polyolefin family, it has excellent vulcanization properties. Among all rubbers, EPDM has the lowest specific gravity. It can absorb a large amount of fillers and oils without affecting the characteristics. Therefore, a low-cost rubber compound can be produced.
Molecular structure and properties
Tripropylene is a terpolymer of ethylene, propylene, and a non-conjugated diene. Diene has a special structure, and only one of the two bonds can be copolymerized. The unsaturated double bond is mainly used as a crosslink. The other unsaturated one will not become the polymer backbone, but only the side chains. The main polymer chains of EPDM are fully... less
