PPA (Fluoropolymer Processing Additive)
Working principle of PPA (Fluoropolymer Processing Additive):

 

Uses: Suitable for various resin extrusion processes, eliminating and improving melt fracture, and improving the extrusionprocessability of low-melt index resins. Application areas: LLDPE, LDPE, HDPE, PP, PS, PET.Specifically in the extrusion process, Fluoropolymer Processing Additive can be dispersed in the melt of thermoplastic resin with aparticle size of 0.5~2um. After the melt is mixed in the extruder, under the action of surface tension, Fluoropolymer ProcessingAdditive will move to the melt. The outer layer of the melt moves; and tends to adhere to the metal surface, forming a dynamiclubricating layer between the cavity inside the extruder, the surface of the die and the polymer body to reduce the friction betweenthe melt and the wall during movement , thereby reducing the shear rate and viscous drag of the melt in the mold. The lubricatinglayer on the metal surface is a dynamic trend, which is constantly taken away and replenished. The minimum addition amount is toensure a continuous lubricating layer on the metal surface of the extruder head.The lubricating layer formed by Fluoropolymer Processing Additive is coated on the uneven metal surface to establish a dynamicTeflon coating. When the process reaches dynamic equilibrium, the extrusion pressure, torque of the extruder, and the apparentviscosity of the melt will decrease .

Use ProcessImprove the dispersion of fluoropolymer processing additives,3-5% masterbatch is recommended to be first made by twin screwextruder and then added to extrusion resins according to target additive amount. In first-time use, there will be 20-40 min onsettime according to equipment, raw material and shearing speed. For equipment that long-term continuously uses fluoropolymerprocessing additives, there's no onset time.Matters needing attention1. After each granulation, quickly isolate the air and seal it up to prevent moisture absorption. Do not expose powder or mastermaterial to air for a long time2. In case of abnormal phenomena such as surface discoloration and water accumulation due to moisture absorption, stop usingthe product immediately and consult the manufacturerBelow is produced in accordance with standard manufacturing processes for the product in effect at the time of manufacture and iscertified to meet the specifications displayed below.Shelf Life:24 MONTHS FROM DATE OF MFG Storage Condition for this Product:GENERAL WAREHOUSE STORAGE(IN ORIGINAL, UNOPENED CONTAINER)

 

Fluoropolymer Processing Additive Application Process

1. Fluoropolymer Processing Additive product performance is to eliminate and improve melt fracture, improve the processingperformance of polyolefin resins, the addition amount is extremely low 300~1000ppm.2. The dispersibility of Fluoropolymer Processing Additive in polyolefin resins determines the use effect. Because the amount ofFluoropolymer Processing Additive added is very small, powder Fluoropolymer Processing Additive products need to be made intomasterbatches.3. Conducive to dispersibility, the concentration of master batch preparation: control below 5%, add 2‰ of antioxidant, it isrecommended to make 3% master batch, and the addition amount is 1~3%.4. Stirring process requirements: use a common mixer to avoid high temperature agglomeration during mixing.

 

5. Suggested pelletizer temperature:

temperature value	temperature range
<196ºC	80ºC 160 ºC 165ºC 175 ºC 185 ºC

 

6. When it is used for the first time, it is necessary to thoroughly clean the equipment. When starting the machine, run it with a highconcentration masterbatch for about 20 minutes, and then reduce it to a normal concentration of 3% for production. The onset timeis 20-60 minutes depending on equipment, base material and shear rate.7. There is no effective time for long-term continuous use of Fluoropolymer Processing Additive products.
8.Recommended dosage: 300~1000PPM

 

Fluoropolymer Processing Additive Solutions to Eliminate and Improve Melt Fracture


The main function of Fluoropolymer Processing Additive is to eliminate and improve the melt fracture of polyolefin materials andimprove the processing performance of the resin without changing the properties of the resin itself.Fluoropolymer Processing Additive utilizes the ability to eliminate and improve the melt fracture of polyolefin materials to solve theshark skin phenomenon that occurs in extrusion processes such as film making, extrusion, and wire drawing.The reason for the phenomenon of shark skin is that the resin melt produces shark skin when extruded at high temperature andhigh speed. The frictional force of the die wall acts on the outer layer of the melt at the outlet, and the outer layer of the melt issubjected to tension, and the fluid elastically retracts. , In the state of high-speed extrusion, it will cause melt rupture and produceshark skin phenomenon.solution:Lower tension (pressure), lower throughputlower molecular weightChange resin compositionIncrease processing temperatureChange die sizeAdd 0.3~1‰ Fluoropolymer Processing Additive

Fluoropolymer Processing Additive solution for gelation during film production

 

Reasons for gel formation during film making:1) Unmixed/unmelted gel: equipment defects (screw structure, die size) make the material mixed unevenly, which will lead to gelformation.2) Cross-linked gel: The "dead corner" of the equipment is the degradation point, which is easy to generate gel; improperoperating temperature also leads to the generation of cross-linked gel. The carbon radical center crosslinks PE into high molecularweight PE.3) Oxidative gel: fiber or other resin contamination; inorganic additive agglomeration; gel in the polymer; the process of oxidativegel production is that the oxide sticks to the die wall, as a point for other oxidation of the polymer, High concentrations of oxidesare produced, resulting in cross-linking.solution:Continuously add Fluoropolymer Processing Additive 800~1000ppm, use Fluoropolymer Processing Additive lubricating layer tocoat the die wall, establish a dynamic lubricating layer, in a dynamic balance, to avoid the accumulation of material on the die wall;Fluoropolymer Processing Additive with good thermal stability will not cross-link Low molecular components can eliminate andreduce die gel phenomenon, improve production efficiency and reduce waste rate.Fluoropolymer Processing Additive utilizes the ability to eliminate and improve the melt fracture of polyolefin materials to solve thephenomenon of die precipitates in extrusion processes such as film making, extrusion, and wire drawing.During the extrusion process, the extrudate will gradually deposit at the exit of the die, forming a die deposit, or die precipitate; itseriously affects the quality of the product, mainly manifested in the decline of the mechanical and optical properties of theproduct, and the deterioration of the product. Poor surface finish.Reasons for the phenomenon of die precipitates Reasons for using equipment 1) The change of screw pressure during the working process;2) Influence of melt melting temperature;3) The speed of the equipment changes;4) The cleanliness of the die;5) Processing size of die: inlet size, length, outlet angle, shrinkage change, melt flow rate, die expansion ratio;Raw material reasons1) Raw materials contain low molecular weight substances;2) packing;3) The dispersibility of the material: the raw material is not uniformly dispersed; the viscosity of the components is different, andthe dispersion is not uniform;4) Humidity and volatile matter; Solution and improvement plan: add 0.5~1‰ Fluoropolymer Processing Additive
