MTR Process (without SSP) Advantages -
• Lower residence time resulting in minimal generation of secondary products & cross linked polymers
• More stable parameters - consistency in product quality
• Lower Crystallinity - Better strength and lower energy requirements during downstream processing
• Lower temperature processing - less thermal degradation , reduced AA regeneration and minimum secondary products
generation
• Spherical shape of pellets - Lower dust generation and lower IV drop during downstream processing
• Lower thermal heat stress - Reduced haze due to less carboxyl end group and low thermal degradation
• Narrow processing window - Due to narrow molecular weight distribution and improved process-ability

Spherical pellets and smooth rounded edges, o Very low fines in resin. © Negligible fines generation in conveying, resulting in
less filter cleaning, better dryer efficiency o Better air flow around the pellets in dryer, hence quick
drying.
Low crystallinity • Quick melting, less temperature in feed zones, resulting
in lower heater load. © Lower residual AA generation.
reformTrials: GP01 Vs SSP Resin
Drying temperature less by 10 deg C
• Drying temperature reduced from 180 deg C to 170 deg C • Drying time reduced from 6 hrs to 5 hrs. • Lower drying energy to a tune of 4% of total conversion
power.
Plasticization temperature • Feed zone temperature down by 20 ~ 30 deg C
Lower heat energy input by heaters to a tune of 1% of conversion power.
Total heat input saving 5% of conversion power.

Total conversion energy of system: o.5KWH/Kg (typical)
Savings in conversion power: 0.025 KWH/Kg
Typical capacity of machine: i6,oooKgs/day
Savings/day: 400KWH
Savings/ annum: 124,000 KWH
Considering 5 cents/ KWH, - Saving: $ 6,200/annum/machine.

GP 01 - Blow molding The inherent color t in t of the polymer from MTR technology increases the heat absorption f rom the infrared heaters
• High heat absorption results in uniform heat distribution across the cross section of the preform resulting in easy stretching.
• The uniform heat content across the cross section of the preform, increase the total heat content of the preform, thus enabling the preform to be stretching into extreme surfaces and intricate corners of the bottle easily; like the petalloid legs of smaller bottles, which is difficult to form.
• The high heat absorption also helps in improving the throughput in high speed blowing machines.
• Maintain lower oven temperature and lower exhaust percentage, which reduces the heat loss to the atmosphere.
• The typical energy saving in blowing, for a 4 m m thick preform is 4 ~ 5% of the heater output, compared to any standard non-fast reheat resin.
