Domestic PP pelletizers hit record high

Drying equipment

Chinese dried Reuters by strengthening management, improving production techniques and stable level devices, as of November 23, Zhongyuan Petrochemical Company made large-scale Polypropylene extrusion granulator group smooth high-load continuous operation 75 days, creating a large domestic polypropylene A new record for the operating cycle of the extrusion granulator.

The 100,000-ton/year polypropylene plant is a supporting facility for China Petrochemical Coal Chemical Demonstration Project - Zhongyuan Petrochemical's 600,000-ton/year methanol-to-olefins (MTO). The extrusion granulation unit is a domestically-developed large-scale domestically-developed equipment. , The process is very demanding.

Thermoplastic Elastomer

Styrene-isoprene block copolymers (SIS) are large volume, low priced commercial Thermoplastic Elastomer which are produced by living ionic copolymerization by sequentially introducing styrene, 2-methyl-1,3-butadiene (isoprene), and styrene into the reactor. Tpe Thermoplastic Elastomer content typically varies between 15 and 40 percent. When cooled below the melting point, SIS`s with a low styrene content phase-separate into nano-sized polystyrene spheres imbedded in an isoprene matrix whereas an increase of the styrene content leads to cylindrical and then to lamellar structures. Thermoplastic Polyamide Elastomers styrene domains function as physical crosslinks which provide mechanical strength and improve the abrasion resistance, while the isoprene rubber matrix provides flexibility and toughness. The mechanical properties of SIS elastomers with a low styrene content are similar to those of vulcanized rubbers.

As a kind of Rubber And Plastic,unlike Pvc Resin ,Eva Resin or Pvc Paste Resin,Sis Rubber are often blended with tackifier resins, oils and fillers, Thermoplastic Silicone Elastomer allows for a versatile modification of product properties or they are added to other thermoplastic polymers to enhance their performance.

Thermoplastic Elastomer Sisare widely used in hotmelt adhesives, sealants, gasket materials, rubber bands, toy products, shoe soles and in bitumen products for road paving and roofing applications.
