Things You'll Need
- 2 samples PTT polymer carpet
- 2 samples PET polymer carpet
Instructions
Give your polyethylene trimethylene terephthalate (PTT) and polyethylene terephthalate (PET) carpet samples a wear test. According to Beaulieu of America, the molecular structure of the PTT polymer is stronger than that of the PET polymer. The carpet sample that shows more wear after a mechanical test may be identified as the PET carpet sample.
Read what each carpet manufacturer has listed as the carpet's flame resistance rating. Ratings are based on a carpet's laboratory tested and confirmed melting point. The lower the melting point, the higher the flammability of the carpet. The carpet sample with the highest resistance to flame may be identified as the polyethylene terephthalate polymer carpet.
Perform a chlorine bleach test on your second set of polyethylene trimethylene terephthalate (PTT) and polyethylene terephthalate (PET) polymer carpets. According to Beaulieu of America, PTT polymer carpets are highly resistant to chlorine bleaching. Based on this information, your more highly stained sample may be confirmed as PET polymer carpet.
Go on a shopping trip to compare the costs of polyethylene trimethylene terephthalate (PTT) polymer carpets and polyethylene terephthalate (PET) polymer carpets. PET polymer carpets will be cheaper as they are less costly to produce than PTT polymer carpets.
