WHAT IS PP?

What is PP?

Jan262016مدیر

Polypropylene (PP) is a linear hydrocarbon polymer, expressed as CnH2n. PP, like polyethylene and polybutene (PB), is a polyolefin or saturated polymer.

Professor Giulio Natta produced the first polypropylene resin in 1954. Natta utilised catalysts developed for the polyethylene industry and applied the technology to propylene gas. Commercial production began in 1957 and polypropylene usage has displayed strong growth from this date. The versatility of the polymer (the ability to adapt to a wide range of fabrication methods and applications) has sustained growth rates enabling PP to challenge the market share of a host of alternative materials in plethora of applications.

Production of polypropylene takes place by slurry, solution or gas phase process, in which the propylene monomer is subjected to heat and pressure in the presence of a catalyst system. Polymerisation is achieved at relatively low temperature and pressure and the product yielded is translucent, but readily coloured. Differences in catalyst and production conditions can be used to alter the properties of the plastic. (more…)

SPHERIPOL PROCESS

Spheripol PP

Jan262016مدیر

pp00002Jam polypropylene is licensee of Basell`s Spheripol process that produces a wide range of premium quality polypropylene products.

Today’s Spheripol process is the result of 40 years of continual improvement. However, to truly appreciate the unique capabilities of this technology, it is helpful to understand the evolution of the PP industry and the breakthroughs that led to discovery of the Spheripol process.

In the 1960s, PP processes employed first-generation low-yield catalysts (<1000 kg PP/kg catalyst) in mechanically stirred reactors filled with an inert hydrocarbon diluents. Polymer produced with these catalysts had unacceptably high residual metals and contained 10 percent atactic PP, which required separation. Removal of catalyst residues and atactic PP involved treatment of the polymer with alcohol, multiple organic and/or water washings, multistage drying, and elaborate solvent, amorphous, and catalyst separation systems. These processes were costly and difficult to operate; they also required extensive water treatment facilities and catalyst residue disposal systems. (more…)

TROUBLESHOOTING GUIDE

Troubleshooting is the art and science of remedying defects after the process has demonstrated the ability to produce acceptable production parts. Most defects respond to one of a variety of process and/or material changes. The goal is to correctly identify which problem is actually causing the defect and to know when a particular solution will work. When making adjustments consider the following recipe:

• Create a mental image of what should be happening,
• Look for obvious differences,
• Make only one change at a time, and
• Allow the process to stabilize after any change is made.

Studies have determined that about 60% of defects result from machines and equipment, 20% from molds and dies, 10% from material, and 10% from operator error. Software programs, either already installed on the machine’s processor controller or available as a software package, can provide some help.
With all types of equipment, materials, and products, troubleshooting guides are set up (usually required) to take fast, corrective action when products do not meet their performance requirements. This problem-solving approach fits into the overall fabricating-design interface.
To understand potential problems and solutions (and eliminate myths), it is important to consider the relationships of machine and equipment capabilities, plastics processing variables, and product performances. A distinction has to be made between machine conditions and processing variables. Machine conditions could include operating temperatures, back pressures, screw rotation speed, die temperature, etc. Processing variables are more specific, such as melt conditions in the plasticator and die, melt flow rate versus temperature, etc.
When setting up troubleshooting guides, as well as reviewing any problems or even open discussions on the subject of fabricating, it is important that the terms used to identify a problem be understandable, clear, and properly defined.
Different terms are used throughout the industry to identify defects in plastic materials, fabricating equipment, and products. They include adhesive stringing, air bubble, applesauce, arrowhead, black speck, bleed, blister, blockage, bloom, blowhole, blush, burn line, chalking, coating defect, cosmetic defect, compressive buckling, crazing, degradation, electrostatic charge, fin, fines, fish-eye, flash, fracture, flaw mark, freeze-off, frosting, gas pocket, gel, globule, hairline, migration, orange peel, paint framing, pimple, pin hole, pit, plastic pocket, plate-out, pocket, pock mark, puckering, run, sag, scale, segregation, shark skin, sink mark, speck, splay mark, stain, starved area, streak, stress whitening, striation, surface finish, trim, void, weld line, yellowing, and so on.
