Problems solved by technology

The second disadvantage is that black CCS tend to absorb sunlight and thus be heated
However, the relatively high cost and relatively low modulus and strength properties of these polymers limit their widespread use in CCS applications

Embodiment 1

[0090] Five UHH-resistant mixes (INV1-INV5) and one reference mix were prepared. Their compositions are shown in Table 1. Additionally, each blend contains 0.5% TiO 2 Pigments (Kronos TM 2222, produced by Kronos) and 0.2% of PV Fast Brown HFR TM Brown pigment (manufactured by Clariant). The polymer, additives and pigments were fed into the main hopper of a co-rotating twin-screw extruder operating at 100-400 RPM with a barrel temperature of 180-240 degrees Celsius. The polymer is melted and the additives are dispersed in at least one kneading zone. Filling is provided by a side feeder. Water vapor and gases are exhausted from the atmospheric vent and the resulting product is pelletized in a strand pelletizer.

Embodiment 2

[0110] Five mixtures INV6-INV10 and one reference mixture were prepared. Their compositions are shown in Table 4. Additionally, each blend contains 0.5% TiO 2 Pigments (Kronos TM 2222, produced by Kronos) and 0.2% of PV Fast Brown HFR TM Brown pigment (manufactured by Clariant). The polymer, additives and pigments were fed into the main hopper of a co-rotating twin-screw extruder operating at 100-400 RPM with a barrel temperature of 260-285 degrees Celsius. The polymer is melted and the additives are dispersed in at least one kneading zone. Filling is provided by a side feeder. Water vapor and gases are exhausted from the atmospheric vent and the resulting product is pelletized in a strand pelletizer.
