Problems solved by technology

[0003] In recent years, the PVC pipe fittings industry has developed rapidly, but due to the poor thermal stability and heat resistance of PVC, the plasticizing effect is unstable and easy to volatilize and migrate; when preparing hard products, the apparent viscosity of the melt is high, the processing fluidity is poor, and the hard products are Brittle, poor impact resistance, which greatly limits its use
