The Clear Cap Protector is a patented product manufactured from Dupont crystal clear Surlyn® (8942 PT) thermoplastic resin. This result is a transparent protector, enabling a visual corrosion inspection of the thread section without loosening the protector or moving the pipe from the storage area.
Surlyn® (8942 PT) is a plastic ionomer providing transparency and mechanical strength unequalled by other polymer types. The material is i.e. used for golf balls, and it is ideal for OCTG protectors as it is resistant to chemicals and can be machined.
