트포 대부분은 ABS로 만들어진다고 하는 듯

  • Acrylonitrile butadiene styrene (ABS)
Strong and tough "engineering plastic". Lego bricks and car bumpers are made from ABS. The majority of any given Transformer toy is likely to be made of this. ABS also seems to suffer from a condition called Gold Plastic Syndrome when colored the swirled, metallic goldish-bronze color seen on some figures. However, not all gold plastic suffers from this; it seems to occur mostly in older plastics (pre-RID). This issue appears to be largely fixed in newer toys. The transparent version of the plastic is called MABS (Methacrylate Acrylonitrile Butadiene Styrene)

그리고 망할 놈의 골든 플라스틱 신드롬도 ABS 특징 중 하나였다고 하네.
