Transparent Cup Production Using PP Enhanced with Milliken’s Clarifier at K 2016

Published on 2016-10-07. Author : SpecialChem

GHENT, Belgium -- Victor Taichung Machinery Works Co. Ltd. will be demonstrating on its booth at K 2016 the clear advantage that processors get when they use INEOS polypropylene made with Milliken & Co.’s Millad® NX™ 8000 clarifier technology.

Clear PP Cup Production at K 2016

The Taiwanese machine maker has planned to process some 1,300 kg of INEOS’ 100-CC60 grade of PP resin on Stand 13 in Hall B38 during the Oct. 19-26 trade show in Düsseldorf, Germany. Victor Taichung says it will produce the clear PP cups in a four-cavity mold running on its new VM-280E injection press, which it is introducing at the fair. The setup also will employ an in-mold labeling automation system supplied by Jet Engine Automation Co. Ltd.

Victor Taichung developed the machine last year specifically for the manufacture of thin-walled objects. The VM-280E features a robust, heavy-duty clamp system and a single-piston injection unit with closed-loop servo valve for short cycle times and high-speed injection.

Milliken partnered with Victor Taichung at the last K fair, in 2013, and also has a long-standing relationship with INEOS -- all of which ties in perfectly to Milliken’s K show theme of “Making Polypropylene Clearer, Better, Faster. Together”.

INEOS, meanwhile, says its 100-CC60 grade offers a unique combination of high stiffness
(flexural modulus = 1800 MPa and tensile modulus = 1950 MPa), very good flowability and moldability (MFR = 60g/10min), and high clarity (Haze = 17% on 1mm plates).

Gaëtane Hallot, the INEOS Senior Technical Service & Product Development Engineer & Material Developer, said:
“Other polypropylene grades on the market offer one or two of these properties but with 100-CC60, we have combined all these top performances in one single material. She sees the ideal applications for 100-CC60 as being highly transparent, thin-wall injection molded packaging trays, buckets and cups or storage boxes, but also sees potential applications for it in all molded parts that require high stiffness, thin walls and high clarity, and that are used at room temperature.”

Gaëtane Hallot explained:
“The first property we were looking at when testing Millad NX 8000 as clarifier for our PP 100-CC60 was the best possible clarity.”

Additionally, INEOS wanted to maximize the benefits for the molder by offering a very homogeneous material with excellent dispersion of all additives, the absence of yellow taint and the possibility to develop the best optical properties when molding parts at low temperatures.

Milliken Clarifier in PP Resin

Using the Milliken clarifier in PP resin offers additional benefits to the user.
  • Millad NX 8000 allows processors to reduce molding temperatures compared to resins made with previous-generation clarifiers. 
  • This in turn helps converters to better meet sustainability goals by reducing energy consumption and shortening cycle times. 
  • The lower molding temperature also shortens the cooling time of the part prior to ejection from the mold, further speeding production and boosting productivity.
