JS36 twin screw test extrusion line

EVA is an elastomeric polymer that produces materials which are "rubber-like" in softness and flexibility. The material has good clarity and gloss, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to UV radiation. EVA has a distinctive vinegar-like odor and is competitive with rubber and vinyl polymer products in many electrical applications.

EVA is also used in biomedical engineering applications as a drug-delivery device. The polymer is dissolved in an organic solvent (such as dichloromethane). Powdered drug and filler (typically an inert sugar) are added to the liquid solution and rapidly mixed to obtain a homogeneous mixture. The drug-filler-polymer mixture is then cast into a mold at −80 °C and freeze-dried until solid. These devices are used in drug delivery research to slowly release a compound. The polymer does not biodegrade within the body, but is quite inert and causes little or no reaction following implantation.

The mass material  by elevator, conical screw feeding machine, extruder,  cutting, cooling, screening and terminal silo，produce  processing full automation .After the material were refined , trough feeding it is forced to enter the single screw extruder . The core of the screw is connect with water, and the screw is completely dispersed without excessive friction heat.Excellent dispersion effect, the current of main machine is small, energy saving and environmental protection.The precise temperature control of the rubber granulator ensures the technology of low temperature granulation and the special isolation agent recovery system, which can effectively solve the dust problem in production.
