U.S. Develops Novel Additives for Processing a Wide Range of Plastic Resins

Phoenix Plastics USA is a professional supplier of specialty additives. Recently, a new variety of additives with the brand Cell-Span was introduced. Compared with other traditional additives, the new additives can improve the processing properties of rubber and plastic resins, and thus can process more plastic products (expanding the application range of products). This unique additive is currently being applied for. patent. According to reports, after the addition of this additive, unexpected improvement effects can be obtained during the processing of plastic products, such as shortening the injection molding cycle time and increasing the processing productivity.

The Cell-Span additive series was successfully developed under the auspices of Webster. He is an expert in plastic and fiber chemical additives. After continuous exploration and research, Cell-Span series additives have gained market recognition.

Low cost advantage is significant

There are 7 varieties of Cell-Span processing aids, all of which are derived from the same basic compound, especially formulated for various plastic products. The scope of application includes polyolefins, PS, PVC, ABS, PC, PET, PBT, and PA. Webster said: "We have explored a new path for the production of existing compounds that are no longer limited to the production of plastic additives. These super (high) molecular weight polymers are formed by hydrogen bonding, and their bonding power exceeds that of ordinary ones. The covalent bond in the compound.

According to Webster, the application of these specialty additives eliminates the need for any processing aids in the processing of plastic products, such as stearates, amides and fatty acid lubricants used in the production of polyolefins, as well as in the production of PVC uses high heat-resistant styrene resin and paraffin wax. The Cell-Span series can also replace some primary and secondary antioxidants and nucleating agents. ”

According to reports, the new additives are highly cost-effective and have been extensively tested to yield the same data. In the case of 20% additives added to plastic resins, many common additives can only reduce processing costs by 1% to 3%. , The application of new additives can reduce the cost by another 0.2% to 1%, and the application prospects are extremely attractive.

Tested in HDPE resin, using Cell-Span 610 grade additives for injection molding, processing 2 pounds of HDPE green plastic barrels, can reduce the molding cycle by 5 seconds, the cost is reduced by 25%, and the single piece cost is reduced from USD 1.52. For $1.45, the cost savings of $2509.44 per month can be saved in addition to the cost of auxiliaries.

The Cell-Span 610L should be added to the unfilled homopolymer PP material. The cycle time for processing the PP coloring part is only 10 seconds, the cycle time is reduced by 36%, and the cost per month can be reduced to 4166.77 US dollars.

The talc-filled homopolypropylene material was added with 610L grade auxiliaries, and the talc filler was 30%. Injection molding was performed using an injection molding machine with a 750-ton clamping force, and the cycle time was reduced from 83 seconds to 52 seconds. In addition, if the amount of talc is 15%, the processing cycle is reduced from the original 76 seconds to 52 seconds, which is 31% lower than the use of common additives.

When processing PP random copolymers, Cell-Span 610 grade additives should be added, the coloring process is shortened by 13 seconds, a reduction of 17%, and a monthly savings of 700 US dollars.

Adding 610L brand auxiliaries to PP with 30% glass fiber reduces the processing cycle time to 80 seconds, a drop of 36%, saving 1,026 US dollars per day and saving 30,805 U.S. dollars per month.

In the process of processing foamed polypropylene, despite the use of a diathermic blowing agent, the surface of the PP material is inevitably recessed. After the 610L brand additive was used, the surface of the product was scratched and the depression disappeared.

In the injection processing of soft PVC products, after the addition of 605 brand additives, the barrel temperature can be reduced from 320 to 330 degrees Fahrenheit to 230 to 250 degrees Fahrenheit, and the cycle time is reduced by 6 seconds.

When extruding hard PVC products, 608 grade additives can be used. Extrusion parameters of the extruder can be changed from 52ams, 18rpm, 305-365 degrees Fahrenheit to 39ams, 26rpm, in the process of squeezing the initial product profile. 205 to 300 degrees Fahrenheit. This means that the extrusion rate increased by 63% from 330 lbs/hr to 538 lbs/hr.

Injection processing PS products should use 610 grade additives, processing cycle can be shortened by 25 seconds, a reduction of 45%, thus saving $ 6,922 per month.

Injection processing ABS products should use 610L brand additives, the cycle can be shortened by 16 seconds, a reduction of 23%, with an injection molding machine with a clamping force of 500 tons as an example, the hot runner temperature is reduced from 490 degrees Fahrenheit to 450 Fahrenheit degree.
