| Description: | Plastic Chemicals Introduction: Makes the Rigid PVC work better is a versatile plastic having an excellent combination of strength, chemical inertness, and fire resistance. It is, however, difficult to fabricate. Its poor hot strength and lack of cohesiveness at processing temperatures prevent it from flowing smoothly through processing machinery. Additionally, calendered and extruded PVC products may exhibit surface imperfections such as air streaks and melt fractures. Indofil K-120ND processing aid is a highly dispersible powder that prevents many problems associated with PVC processing. The excellent disperibility of Indofil K-120ND processing aid results in fewer gels of fish eyes in clear vinyl formulations. Compounds containing one to five percent of the processing aid fuse rapidly, flow smoothly, have excellent hot strength, and are readily formed. Clarity, rheology, heat stability, and crease whitening resistance of PVC modified with Indofil K-120ND processing aid are maintained. Additionally, the process used to manufacture Indofil K-120ND processing aid enhances powder flow and achieves molecular weight consistency.
