Outline: No matter what processing way is adopted in PVC products processing, PVC compound must be perfectly blent at first, only adopting PVC compound with a suitable fusion degree, PVC finished products can obtain the ideal appearance and mechanical property.Comparing with the other general PVC, un-plasticized PVC could be blent only at a higher temperature and shear force. However, PVC is easy to decompose at a higher temperature. For ensure the hard PVC quality of product, the PVC compound should be processed at a temperature as lower as possible, so the acrylic processing aid HL-125 which is developed by us is provided with fusion-promotion function due to the following features:

1. Owing to its melting temperature is lower than that of PVC, it will be melted earlier than PVC resin and penetrate into the granulars of PVC resin. Then promote the plasticization of PVC resin

2. Easily blending with PVC particles, raising inside frication and increasing electric current and torque of extruder in processing, then ensuring PVC plasticization at lower temperature

3. Because of enough high-molecular weight of our processing aid HL-125, it will increase the melting viscosity (or strength) of PVC melting body, then ensure the PVC compound to be plasticized under the high electric current, torque and pressure conditions Technical specifications:

1) Appearance: White powder

2) Sieve residue (0.45mm) (%): ≤1.03) Volatile contents (%): ≤1.34) Bulk density (g/cm3): 0.35-0.425) Intrinsic viscosity (η): 2.3-2.7

Advantage characters:

1) Improves gelation of PVC

2) Reduces blending time, increases productivity and decreases processing temperature

3) Changes the fluidity of the melting body and improving production rate

4) Better dispersion of additives into PVC, more homogenous melt of PVC

5) Superior glossy property in surface

6) Excellect stripping property

Main use: It is mainly used and added in rigid PVC products such as PVC profile, PVC pipe, PVC sheet, PVC fitting, PVC board and other transparent PVC products.
