Champion Blue Flame Synthetic Blend series engine oils are designed to provide industry-leading performance to meet the needs of the next generation of heavy duty engines. Increased power density, reduced oil volume and extended drain intervals place unique demands on engine oils to control oxidation by-products, sludge and deposits. Due to higher shear stress and lower viscosity minimums for engine oils, only oils with the highest wear protection and viscosity stability can maximize the performance and life of advanced diesel engines.

Oxidation Control- Champion Blue Flame Synthetic Blend series engine oils take oxidation resistance to another level, allowing users to achieve longer drain intervals, reduce maintenance and downtime, and extend engine life. Controlling oxidation, corrosive acids, sludge and varnish precursors allows for extended drains and minimized wear even under the most extreme conditions. Synthetic base oils provide reduced volatility and oil consumption, further reducing the build-up of sludge and varnish. Oxidation lower than OEM limits in over 60,000 mile on-highway and 600 hour off-highway drain intervals.â?¢ Proprietary additives and synthetic base oils have shown up to 80% reduction in Volvo T-13 oxidation.

Wear Control- Champion Blue Flame Synthetic Blend series engine oils keep your engines going longer by reducing engine wear, preventing high temperature corrosion and controlling abrasive soot contamination, even while allowing for improved fuel economy and lower total cost of ownership. Synthetic base oils improve cold-flow properties and reduce start-up wear, leading to extended engine life and performance. Over 75% less pushrod wear, 85% less injector screw wear and 70% better resistance to filter-plugging than CJ-4 oils in proprietary, extra-severe engine testing. Outperformed corrosion bench testing limits by 70% for copper and over 98% for lead and tin.â?¢ Cold-pumping viscosity 72% lower (SAE 15W-40) and 69% lower (SAE 10W-30) than J300 limits, providing excellent lubrication and wear protection at start


Part# 4358N/4 4/1 Gal.
Part# 4358U/2 2/2.5 Gal.
Part# 4358AN 55 Gal.

Also known as ground quartz and silica flour, is produced by grinding high-purity quartz, quartzite, sandstone, or silica sand to finer than 45 micron. Air separation is used as required to remove kaolin, mica, feldspar, or calcite impurities.
we can crush also reach 45 micron with magnetic separation
Uses:
1- glass industry
2- lenses industry
3- television, radio, computer, radar, transmission machine industry
4-pure quartz for photocells
5- semi conductor industry
6-Cleaners
7-Paint
8-cramics: Low-iron ground silica, typically -200 mesh, and calcined silica are used in whiteware formulations to facilitate drying of the body, to control expansion characteristics and compatibility between the body and glaze to prevent crazing, and to provide whiteness and acid resistance.
10-Coatings Ground quartz and novaculite are used as extender pigments because of their low binder demand, which allows high loadings.
11-Rubber Finer (<0.025 micrometer) precipitated silica is the only fully reinforcing alternative to carbon black for general rubber compounding. Most of the precipitated silicas used in rubber are reinforcing grades rather than the coarser extending grades. Precipitated silica is used in compounds designed to be translucent or colored, and in general compounding to promote abrasion resistance, cut growth resistance, tear strength, elastomer-to-textile adhesion, and resistance to heat aging.
12- Plastics: are used as thixotropes in unsaturated polyester resins and gel coats and in epoxy resins. Fumed and precipitated silicas are used as thixotropes in PVC plastisols. used as ant blocking and antislip agents by temporarily absorbing plasticizers that can cause tack and by providing an imperceptible surface roughness. They are used as matting or flatting agents and as plate-out agents in highly plasticized compounds.
