1. WHAT IS POLARTECH 7600?
POLARTECH 7600 (PT 7600) is a emulsifier and corrosion package for soluble oil manufactured by ITALMATCH CHEMICAL. When using Polartech 7600 with a suitable amount of base oil and biocide, it will provide a very cost effective soluble oil with outstanding hardwater tolerance and corrosion protection for Ferrous and non-ferrous alloys.
2. WHAT ARE PT 7600 ADVANTAGES?
In contrast to other commercial packages on the market, PT 7600 has some good charecteristics as below:
- PIBSA technology along with SPS and other non-inonic emulsifiers provides a long-term emulsion stability through electrostatic and steric repulsions. Normally, other packages as far as I know will give you a quick blooming, but it cannot give you a longlasting kinetic stability of emulsion.
- PIBSA and other non-ionic emulsifiers assit the finished soluble oil made by PT 7600 to have a good hardwater resistance up to 1000 ppm.
- In my own experience, I found that PT 7600 is easy to be used with 70N/150N and it even can be used to make a semi-synthetic MWF (high-, medium- and low-oil content) with a slight adjustment in formula.
3. ARE COLOR AND BLOOMING RATE REALLY IMPORTANT FOR MWF?
To be honest, cutting machine needs good soluble oil, which cannot be reflected by color, blooming rate, and other quite basic physical properties (i.e., density, viscosity). The difference between good and bad oil is its performance during processing. Unlike engine oil, it takes long-time to unveil the quality for consumers, MWF industry is quite easy to know the performance of MWF at the workshop just few hours or days of operation. Therefore, the quality in the MWF industry is the key factor to evaluate whether a MWF is good to be used or not.
Blooming rate is partly affected by emulsifier structure. The bigger the MW of the emulsifiers, the longer the time it needs to be hydrated. PIBSA is a polymeric emulsifier with high MW than other normal SPS, anionic and non-ionic emulsifiers, it needs time for water to penetrate the carbon chain in the coils to make them easily to move. It means the coil polymer conformation will be bigger and bigger due to hydration, and the interaction between the polymer chain become looser, making them completely hydrating (dissolution).
Soap content is also another factor to inffluence the emulsifying rate of the package. However, this property is not really important than others (e.g., corrosion protection, metal compatibility, hard water tolerance, pH stability)
4. WHY CHOOSING PT 7600?
ITALMATCH develops this product to meet global restriction by those raw materials with stable chemical compositions. It means the products and perfomance will be the same batch-to-batch, so you can concentrate on market development.
PT 7600 is compatible for many metals (i.e., Fe, Al, and Cu). It does not make severe corrosion on metal surface and protect them against oxidation agents.
Although the package is designed for soluble oil, we can assist customers to upgrade the package to make a low-oil semi-synthetic metal working fluids. Especially, to design the soluble concentrate with low break point (e.g., 2-2.5%), our team can help customers adjust the formula to meet their satisfaction.
PIBSA technique provides long-lasting emulsion stability to avoid oil separation resulting to loss of emulsion lubricity.
With higher treat rate, this excellent package can also help the pH stability in long time, so the emulsion can enhance the corrosion protection properties beside prevent bacteria from growing.
In summary, Polartech 7600 is the outstanding package with multi-functional application. In addition, ITALMATCH really focuses on MWF, and they can give you technical support as soon as you need helps. Thus, I strongly believe that Polartech 7600 can make you delighted and reduce risks when selling your finished soluble oil into end-users.
