Second,Product introduction:

    YTPATM - 801 polyester type of chain extender is our company adopts special production process and chemical technology, through epoxy functional groups, and has the degradation of polymer end group produces chemical reaction, to restore its original molecular weight and viscosity, and increase the melt viscosity, lower melt index, low quality of recycled plastics for improvement or improve the processing performance of recycled plastics. This product belongs to the chain extension agent, containing highly active reactive groups are composed of functional monomer polymerization with organic functional groups are widely used in polyester, polycarbonate, nylon polymer, such as recycling.

    Chain extender YTPATM - 801 is through the adjustment and control characteristics of the polyester plastic viscosity to restore and improve mechanical properties, thermal properties, processing properties and optical balance. It is mainly used for PET, PBT, PC, PA, such as polymer processing and recycling.

    Hydrolysis and high shear heat is produced, the degradation of the result is that the material performance is bad, there is a requirement for use in a variety of occasions cannot be recycled. YTPATM - 801 molecular reactive group and thermoplastic engineering plastic reactive groups link reaction, the synthesis, processing, repeated processing and recycling back coupling in the process of degradation of molecular chains, improve heavy molecular weight, so as to improve the performance of, or part of the recovery materials recovery, making the performance of the recycled plastic raw performance close to the original.

    When using simple machining equipment added YTPATM - 801, the characteristics of low viscosity IV polycondensation resin, IV will increase by about 20%, and produces the following results：

    Taken the increase of molecular weight and increase the melt viscosity;

    Can be taken to maximize the molecular weight and structure of branched chain;

    Taken the increase of hydrolysis stability;

    Taken the improvement, granulation, recycled materials processing stability;

    U improve melt strength, improve the productivity of film blowing;

    Taken to improve the compatibility between material system;

    Taken the polymer polymerization time.

Three, for the amount of advice:

    0.3 to 1% for polyester materials modification and recovery processing.

four,Packing:

    10 kg or 20 kg, barrel packaging
